Maxim Integrated / Mbed 2 deprecated MAX32630HSP3_IMU_HelloWorld

Simple demo of BMI160 Library (Accelerometer, Gyroscope)

Dependencies:   BMI160 max32630hsp2 mbed

Run the Code

  • Import it into the mbed online compiler.
  • Compile the program.
  • It will automatically download the .bin file.
  • Drag-drop or copy-paste the .bin file to the programmer drive. (PICO DAPLINK).
  • Open a serial terminal (Putty, Tera Term, etc.)
  • Find the COM port that the device is connected to and set that COM port in the terminal. Adjust the baudrate to 9600.
  • Press the reset button on the microcontroller board.
  • You should now see the accelerometer, gyroscope and temperature values on the terminal with 0.5-second intervals.

Compiling it with IAR

The program can be compiled by IAR Embedded Workbench 7.5 ( IAR compiler 7.80.2) or older versions.
