Maxim Integrated / Mbed OS HSP3_USB_serial

USB serial demo passes data from virtual serial port to debug serial port

Dependencies:   USBDevice 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. Now you should see another COM port on the device manager
  • You should now see the temperature values on the terminal with 0.5-second intervals.
