Maxim Integrated / Mbed OS MAX32630HSP3_IMU_Hello_World

This program demonstrates the use of MAX32630HSP3 board with the MAX30205 sensor which provides accurate clinical body temperature with an accuracy of 0.1°C (37°C to 39°C).

Dependencies:   MAX30205 max32630hsp3

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 temperature values on the terminal with 0.5-second intervals.
