ADC Library : ADS1256 DAC Library : DAC8532
-
Connect a USB cable between the USB port on the board and the host computer.
-
Run the following command to build the example project and program the microcontroller flash memory:
- Mbed CLI 2
$ mbed-tools compile -m <TARGET> -t <TOOLCHAIN> --flash
- Mbed CLI 1
$ mbed compile -m <TARGET> -t <TOOLCHAIN> --flash
Your PC may take a few minutes to compile your code.
Alternatively, you can manually copy the binary to the board, which you mount on the host computer over USB.
