Example Code

This example uses Adafruit’s busio package to create a UART object. It will read 3 characters from the FTDI cable which CoolTerm (Windows) or other terminal emulator is connected to. The script then sends ‘hello world’ to the FTDI cable which will display in the terminal.

# convert bytearray to string
data_string = ''.join([chr(b) for b in data])
print(data_string, end="")
uart.write('hello world')
