| + | >2) In order to fully use the demo, you will need to connect a serial terminal to your Cmod A7. Plug your board into your computer with a Micro USB cable and make sure the board has power. Then open a serial terminal (such as TeraTerm) on your computer. In the terminal application setup the serial port to connect to the appropriate port for your board, with a baud rate of 9600. Then return to the Github Projects Tutorial to finish programming and running the demo. | ||
