# 1 Introduction
The BMV080 sensor driver is the interface between the sensor hardware and the user application running on the host system. The complete sensor driver is provided by Bosch Sensortec to run on the host microcontroller / processor.
The sensor driver offers high-level and feature-oriented Application Programming Interfaces (APIs), hiding the peripheral complexity to the user application developers. It includes a complete set of ready-to-use APIs in order to simplify the development of a user application. These functions can be easily used to develop an user application for a determined use case.

The BMV080 Software Development Kit (SDK) includes the BMV080 sensor driver along with examples for some supported hardware platforms to demonstrate the usage of the BMV080 API and to ease the software integration effort within the user application.

Please refer to the following documents to gather further information about BMV080 specifications.

# 3 Platform Support
## 3.1 Common Example Output Structure
The BMV080 SDK has a unified structure for its example output, which simplifies development activities. Assuming the serial port settings are configured to be compatible with the host platform, the serial console output of the application will appear the same across all platforms supported by the BMV080 SDK. However, it is important to note that certain initial boot messages may be printed from different platforms, which are not included in the example provided below.

- CMake Installation
- SYS GCC Installation

Install CMake for Windows via installer
  - [ Download Page - CMake for Windows x64](https://github.com/Kitware/CMake/releases/download/v3.28.1/cmake-3.28.1-windows-x86_64.msi/)

Install SYS GCC for Windows via installer
- 32 bit Platforms

### 3.2.2 Custom Serial Communication Target
Example source code for communicating with the BMV080 sensor over SPI or I2C protocols using vendor specific frameworks (e.g. STM32 HAL, ESP-IDF, etc.) have been provided along with this SDK. Users can modify this file to fit their needs, e.g. SPI clock speed, SPI channel configuration, I2C Clock Speed, I2C Address. More information about the SPI/I2C communication interface, can be found in the datasheet under section __4.4.2 Communication interface__.

In order to implement a custom serial communication target, functions need to be implemented of type `bmv080_callback_read_t`, `bmv080_callback_write_t` and `bmv080_callback_delay_t` as defined in `bmv080_defs.h`. The pointers to these functions are passed to the `bmv080_open` API to perform target specific sensor read, sensor write and system delay actions. Examples with respect to how this is best done can be found in file `combridge.c`.

### 3.2.3 Using External Interrupt vs Polling
In the following diagrams, you can see the activity diagram for continuous measurement. The light yellow parts are calls to the BMV080 API, and the light blue parts need to be implemented by the application. The sensor readings are obtained by calling the `bmv080_serve_interrupt` routine.  Once a second, the BMV080 will provide new measurement data by calling the function that is provided by the `bmv080_data_ready_callback*` function pointer. The `bmv080_serve_interrupt` routine can either be polled by calling it at least once a second, or the IRQ output from the BMV080 sensor can be used to trigger an external interrupt. Whenever the sensor has data that needs to be processed, it will pull the IRQ line low until the data is fetched. Therefore, the IRQ line should either be served by a level-triggered interrupt, or if an edge-triggered interrupt is used, the state of the IRQ line needs to be checked in the interrupt service routine, as shown in the diagram below.
The external interrupt should only be enabled after the successful initialization of the BMV080 by calling the `bmv080_open` API function. Similarly, the external interrupt should be disabled before calling the `bmv080_close` API function.
If the `USE_EXTERNAL_INTERRUPT` symbol is defined (see platformio.ini build_flags) the SDK will use the external Interrupt line instead of polling to call `bmv080_serve_interrupt`.

| Platform  | API Example Polling | API Example External Interrupt  |
| --------- | --- | --- |
| M4F       | ✔️ | ✔️ |
| M4        | ✔️ | ✔️ |
| M33F      | ✔️ | ✔️ |
| M33       | N/A | N/A|
| M0+       | ✔️ | ✔️ |
| ESP32     | ✔️ | ✔️ |
| ESP32 S2  | ✔️ | ✔️ |
| ESP32 S3  | ✔️ | ✔️ |
| Raspberry Pi  | ✔️ | N/A|


#### 3.2.3.1 Systems without a Real-Time OS (Bare Metal)
For bare metal systems, the BMV080 sensor data can be processed directly within the Interrupt Service Routine (ISR). If `bmv080_serve_interrupt` is directly called from the ISR, the following points need to be considered:
* Set the interrupt priority of the ISR to a low level to prevent blocking other interrupts.
* Adjust the stack size for ISR routines to accommodate the requirements of the BMV080 API.

<table>
  <tr>
    <td> <img src="./api_examples/_common/doc/sdk_continuous_measurement.svg"  alt="1"  ></td>
    </td>
    <td> <img src="./api_examples/_common/doc/sdk_isr.svg"  alt="1"  ></td>
    </td>
  </tr>
</table>

#### 3.2.3.1 Systems with a Real-Time OS
For systems operating on a real-time OS, data from the BMV080 sensor should not be processed directly within the interrupt service routine (ISR). Instead, it should be handled in a separate task. The diagrams below illustrate the basic flow of activities.

<table>
  <tr>
    <td> <img src="./api_examples/_common/doc/sdk_continuous_measurement.svg"  alt="1"  ></td>
    </td>

### 3.2.4 Running ARM Cortex-M4 and Cortex-M4F Example
The BMV080 API example application for ARM Cortex-M4 and Cortex-M4F runs on the Adafruit STM32F405 evaluation board. More information can be found here: [3.2 Platform Support for Embedded Targets](#32-platform-support-for-embedded-targets)

#### 3.2.5.2 Upload and Execute Application
In order to execute the example application on Arduino Portenta C33 board together with the BMV080 EvalKit sensor breakout board, the compiled firmware file from the previous step needs to be uploaded.

Since the Arduino board is not Feather format compatible, the 2 boards need to be wired as shown below:
![Wiring Portenta C33 and BMV080 breakout board](api_examples/arm_cortex_m33f/wiring_diagram_m33f.png)
The partial Portenta schematic in this diagram is taken from [Arduino's website](https://docs.arduino.cc/resources/pinouts/ABX00074-full-pinout.pdf), licensed under [CC BY-SA 4.0](https://creativecommons.org/licenses/by-sa/4.0/).

A [SEGGER J-LINK](https://docs.platformio.org/en/stable/plus/debug-tools/jlink.html#serial-wire-mode-interface-swd) device can be used for the upload process. Additionally, the [Portenta breakout board](https://store-usa.arduino.cc/products/arduino-portenta-breakout) which offers a JTAG connector is needed.

Upload the firmware to the microcontroller using PlatformIO by executing the following batch script 
```
upload_arm_cortex_m33f.cmd [spi | i2c]
```
The script takes the following arguments:
* Host communication interface selection between SPI or I2C. This is an optional argument, with the default being SPI.

An example console output can be seen below.

#### 3.2.6.2 Upload and Execute Application
In order to execute the example application on Feather RP2040 board together with the BMV080 EvalKit sensor breakout board, the compiled firmware file from the previous step needs to be uploaded.

A [SEGGER J-LINK](https://docs.platformio.org/en/stable/plus/debug-tools/jlink.html#serial-wire-mode-interface-swd) device can be used for the upload process.

Upload the firmware to the microcontroller using PlatformIO by executing the following batch script 
```
upload_arm_cortex_m0plus.cmd [spi | i2c]
```
The script takes the following arguments:
* Host communication interface selection between SPI or I2C. This is an optional argument, with the default being SPI.

An example console output can be seen below.
```
C:\BMV080-SDK-vX.Y.Z\api_examples\arm_cortex_m0plus>upload_arm_cortex_m0plus.cmd spi
Usage: upload_arm_cortex_m0plus.cmd [spi|i2c]
Arguments: [spi|i2c] (optional, default: spi)
  spi - use spi as the host communication interface
  i2c - use i2c as the host communication interface
  e.g. to use spi as the host communication interface: upload_arm_cortex_m0plus.cmd spi (default: spi)
  e.g. to use i2c as the host communication interface: upload_arm_cortex_m0plus.cmd i2c

Upon a successful upload, the application firmware will be executed on the microcontroller.

In case there is no J-Link hardware available, the ROM bootloader of the RP2040 can be used. The RP2040 needs to put into Bootloader mode by keeping the Boot button pressed during reset. The RP2040 will show up as a mass storage device, the new program image can be copied to the drive connected to this mass storage device. The neccessary files can be found in build\arm_none_eabi_gcc\release_spi\bmv080_example.uf2 and build\arm_none_eabi_gcc\release_i2c\bmv080_example.uf2.

A USB (CDC) connection can be used to establish a virtual serial port for communication between the host computer and development board.
The following serial port settings need to be used:
- Baud rate: 115200
- Data bits: 8
- Parity: None
- Stop bits: 1

After configuring the serial port settings, the application's output can be seen in the serial console. The successful output message will look as stated in the chapter  [3.1 Common Output Structure](#31-common-output-structure).

#### 3.2.7.2 Upload and Execute Application
In order to execute the example application on the ESP32 board together with the BMV080 EvalKit Sensor breakout board, the compiled firmware file from the previous step needs to be uploaded.
Upload the firmware to the microcontroller using PlatformIO by executing the following batch script.

```
upload_xtensa_esp32.cmd comport {esp32 | esp32s2 | esp32s3} [spi | i2c]
```
The script takes the following arguments:
* COM port that is associated with the board to be programmed. This is a mandatory argument.
* ESP32 variant selection between ESP32, ESP32-S2 or ESP32-S3. This is a mandatory argument.
* Host communication interface selection between SPI or I2C. This is an optional argument, with the default being SPI.

When using the ESP32-S2 board, the bootloader needs to be entered manually before the upload action can be executed.
This can be done by pressing and releasing the _reset_ button while pressing and holding the the _boot_ button.

After upload, the SoC remains in the bootloader and a hard reset needs to be performed manually by pressing and releasing the _reset_ button. Please note that the COM port number differs when the SoC is in the bootloader.

An example console output can be seen below.

#### 3.2.8.2 Upload and Execute Application
In order to execute the example application on the Raspberry Pi single board computer together with the BMV080 EvalKit Sensor breakout board, the compiled binaries and start script file from the previous step needs to be uploaded to Raspberry Pi.

To run the example application on the Raspberry Pi using the start script, follow these steps:
* Copy all the binary files from ```api_examples\raspberry_pi\bin``` and the start script (```run_bmv080_example.sh```) into one folder on the Raspberry Pi.
* Connect to your Raspberry Pi using SSH or open a terminal window on the Raspberry Pi itself.
* Navigate to the location where you copied the contents of ```api_examples\raspberry_pi\bin``` and the start script (```run_bmv080_example.sh```).
* Make sure the start script has executable permissions. If not, you can give it executable permissions using the following command:
```
chmod +x run_bmv080_example.sh
```
* Run the example application using the start script:
```
bash run_bmv080_example.sh [spi | i2c]
```
The script takes the following arguments:
* Host communication interface selection  
  *  Optional argument. One of the following can be specified
     * SPI (Default)
     * I2C
  
Once the script is executed, it automatically configures the necessary environment variable on the host system. Subsequently, it verifies the availability of the SPI or I2C driver and proceeds with the execution of the bmv080_example application. The measurement output is displayed on the Raspberry Pi, as stated in the chapter [3.1 Common Output Structure](#31-common-output-structure).

For I2C, the recommended baudrate is 400kHz. Please check the settings on your Raspberry Pi and change them if necessary.

To properly connect the BMV080 EvalKit HW Breakout Board and Raspberry Pi 4 Model B board using SPI or I2C pins, please follow the wiring instructions below:
* Make sure your Raspberry Pi is powered off and  disconnected from any power source.
* Locate the GPIO header on the Raspberry Pi board. It is a 40-pin header located near the edge of the board.
* Connect the BMV080 EvalKit breakout board to the Raspberry Pi as shown below
* Once the connections are made, verify them to ensure they are secure and properly aligned.
* Power on your Raspberry Pi.
  
![Wiring RaspberryPi 4 and BMV080 breakout board](api_examples/raspberry_pi/wiring_diagram_raspberry_pi_4b.png)

The same wiring can be used for all Raspberry Pi models equipped with the 40 pin GPIO header.

- Installation procedure:

  - Install the FTDI D2XX drivers (see previous paragraph).

### 3.3.2 Custom Serial Communication Target
The SDK provides ready-to-use examples that can be used with the BMV080 EvalKit. The EvalKit uses the FTDI Chip FT4222 USB 2.0 to connect a host PC to the BMV080 via SPI protocol. The FT4222 facilitates the USB to serial conversion, enabling communication between the BMV080 and the host system. More information about the SPI communication interface, can be found in the datasheet under section __4.4.2 Communication interface__.

The middleware library libFT4222H.dll is provided as deployed by Future Technology Devices International Ltd. (FTDI) while the combridge.dll is used to adjust the serial communication interface to meet the requirements of the bmv080.dll API.

In order to implement a custom serial communication target, functions need to be implemented of type `bmv080_callback_read_t`, `bmv080_callback_write_t` and `bmv080_callback_delay_t` as defined in `bmv080_defs.h`. The pointers to these functions are passed to the `bmv080_open` API to perform target specific sensor read, sensor write and system delay actions.

### 3.3.3 Running x64 & x86 Example

# 4 Errata
## 4.1 Incorrect PlatformIO Upload Status Message
PlatformIO may display a "SUCCESS" message at the end of an evaluation, even if the connection with J-Link has failed previously. The following error messages may appear:
- "J-Link connection not established yet but required for command."
- "Connecting to J-Link via USB...FAILED: Cannot connect to J-Link."
  
To solve the problem, you can simply disconnect and reconnect.

## 4.2 ESP32-S3 Feather Board Workaround to Support 400 kHz I2C Communication
The fuel gauge chip LC709203F, which is integrated on the Adafruit ESP32-S3 feather board, needs to be put into operational state to allow communication on the I2C bus shared with the BMV080. This can be achieved by sending the device address of the LC709203F after initializing the bus and before establishing communication with the BMV080. Further information can be found in the datasheet of the LC709203F. Example code can be found below.

```
uint8_t device_address = 0x16;

i2c_cmd_handle_t cmd = i2c_cmd_link_create();
i2c_master_start(cmd);
i2c_master_write_byte(cmd, device_address, I2C_ACK_CHECK_EN);
i2c_master_stop(cmd);

int i2c_num = I2C_MODULE;
i2c_master_cmd_begin(i2c_num, cmd, I2C_TIMEOUT_MS / portTICK_PERIOD_MS);
i2c_cmd_link_delete(cmd);
```

## 4.3 ESP32-S3 Feather Board does not Support 1 MHz I2C Communication
There is a hardware level limitation in the Adafruit ESP32-S3 feather board in which the I2C communication is allowed up to only 400 kHz (See Errata section 4.2). There is instability in I2C communication at a frequency of 1 MHz due to the fuel gauge chip LC709203F. Further information can be found online, e.g. [here](https://github.com/espressif/esp-idf/issues/8741).

## 4.4 ESP32-S2 Feather Board does not Support 1 MHz I2C Communication
There is instability in I2C communication at a frequency of 1 MHz on the Adafruit ESP32-S2 feather board.

## 4.5 Limitations in ArduinoCore-renesas I2C Implementation for Portenta C33 Board
Due to limitations in the framework used for the SDK (framework-arduinorenesas-portenta) I2C communication is unstable on the Portenta-C33 Board.

## 4.6 Limitations in ArduinoCore-renesas SPI Mode 3 Implementation for Portenta C33 Board
Due to limitations in the framework used for the SDK (framework-arduinorenesas-portenta) SPI communication in mode 3 does not work on the Portenta-C33 Board.

## 4.7 Initial Measurement Delay
Upon invoking the `bmv080_start_continuous_measurement()` function, please note that the first measurement will not be immediately available. There is a delay of 2 seconds before this initial measurement can be accessed. However, all subsequent measurements will be readily available every second thereafter.
If an external interrupt is used to trigger the measurements, the initial delay extends to 3 seconds.

## 4.8 ArduinoCore-Renesas on Portenta C33 Board cannot use external interrupt
The ArduinoCore-Renesas framework for the M33 processor assigns the same priority level to external interrupt lines and the USB peripheral. When using the ArduinoCore-Renesas framework with this M33 example application, avoid calling `bmv080_serve_interrupt()` directly from the interrupt service routine (ISR). Failing to do so may result in the USB peripheral not functioning as expected.

## 4.9 Compilation and upload issue for ESP32 variants
For SDK versions 8.0.0 or newer, encountering a CMake compiler mismatch error or an upload failure necessitates a fresh PlatformIO installation. This is due to conflicts with previously installed PlatformIO packages. To rectify this, remove the directory `C:\Users\<current_user>\.platformio` before initiating the build process for ESP32 variants. This ensures PlatformIO reinstalls the necessary tools and dependencies correctly.

## 4.10 Misleading PlatformIO upload status message for ESP32-S2
During the firmware upload process to ESP32-S2 via the `upload_xtensa_esp32.cmd` script, PlatformIO incorrectly displays a "Failure" status message despite the upload completing successfully. It is necessary to manually exit boot mode on the ESP32-S2 Feather board by pressing the _reset_ button.
