When I using the UART port, if I float the port after init the UART it will restart the code, is it need a external pull-up resistor? How about the value?
A quick one, where do I find a list of the err_codes? I have had a look in the documentation and I was expecting to find a table of them, but I couldn't locate one.
Thanks...
