This code is for the STM32 or Pro Micro acting as a payload to the CubeSatSim.
Full instructions are in the Wiki: https://github.com/alanbjohnston/CubeSatSim/wiki/8.-STEM-Payload-Board

Code includes (in rough order of testing):

Blink_STM32_PC13.ino and Blink_Pro_Micro.ino The usual Arduino "Hello World" application that blinks the LED for each board.
This code is for the Sparkfun Pro Micro or STM32 acting as a payload to the CubeSatSim in the STEM Payload board. Using the Pro Micro is stongly recommended, as driver and board installation for the STM32 can be problematic, and fake STM32 boards may not work.

i2c_scanner.ino A handy utility for scanning the I2C bus that displays the results in the Serial Monitor at 9600 baud. If the sensors are installed and the jumpers set to the correct position, the two sensors should be displayed.
Code includes (in rough order of testing):

STEM_Payload_Test_STM32.ino and STEM_Payload_Test_Pro_Micro.ino Blinks the Blue and Green LEDs on the STEM Payload Board and also reads the Temperature and Voltage sensors.
Blink The usual Arduino "Hello World" application that blinks the LED for each board.

bme280test.ino Displays the results of reading the BME280 sensor: Temperature, Pressure, Altitude, and Humidity and displays on Serial Monitor 9600 baud. Requires the following libraries: Adadruit Unified Sensor (specify version 1.0.3), Adafruit_BME280 (specify version 1.1.0)
i2c_scanner A handy utility for scanning the I2C bus that displays the results in the Serial Monitor at 9600 baud. If the sensors are installed, the two sensors should be displayed.

GetAllData.ino Displays the results of reading the MPU6050 sensor: Temperature, X, Y, and Z Axes: Acceleration, Gyor (Rotation Rate), and Angle. Requires the following libraries: MPU6050_tockn.
STEM_Payload_Test Blinks the Blue and Green LEDs on the STEM Payload Board and also reads the Temperature and Voltage sensors.

PayloadOK_STM32_PC13.ino and PayloadOK_Pro_Micro.ino This code answers the query from the Raspberry Pi CubeSatSim software over the UART so that the STEM Payload is marked "OK" in the FoxTelem CubeSatSim-FSK Health tab.
bme280test Displays the results of reading the BME280 sensor: Temperature, Pressure, Altitude, and Humidity and displays on Serial Monitor 9600 baud. Requires the following libraries: Adadruit Unified Sensor (specify version 1.0.3), Adafruit_BME280 (specify version 1.1.0)

Payload_BME280_MPU6050_Pro_Micro.ino and Payload_BME280_MPU6050_STM32.ino This code answers the query from the Raspberry Pi CubeSatSim software over the UART so that the STEM Payload is marked "OK" in the FoxTelem CubeSatSim-FSK Health tab and also replies withe BME280 and MPU6050 sensor data. In FoxTelem, this is displayed as the X, Y, and Z Gyro (dps) and in AFSK mode, it is appended to the telemetry string.
GetAllData Displays the results of reading the MPU6050 sensor: Temperature, X, Y, and Z Axes: Acceleration, Gyor (Rotation Rate), and Angle. Requires the following libraries: MPU6050_tockn.

The STM32 can be programmed using the Arduino IDE with the Generic STM32F103C series board and STM32duino bootloader, Maple Mini port.
Payload_BME280_MPU6050_XS This code answers the query from the Raspberry Pi CubeSatSim software over the UART so that the STEM Payload is marked "OK" in the FoxTelem CubeSatSim-FSK or CubeSatSim-BPSK Health tab and also replies with BME280 and MPU6050 sensor data. In FoxTelem, this is displayed as the X, Y, and Z Gyro (dps) and in AFSK mode, it is appended to the telemetry string.

The Sparkfun Pro Micro can also be programed using the Arduino IDE with the Sparkfun Pro Micro board and AVRISP mkII Programmer.
