I have successfully used some of the print_dbg() functions in SOFTWARE_FRAMEWORK/UTILS/DEBUG/print_funcs.c
Now I wonder if there are similar functions for receiving characters, strings, hex etc. from an USART. I have found the usart_read_char() function in usart.c. Are there existing wrappers, or will I have to make my own?
The call hierarchy of usart_read_char() indicates the answer may be yes...
Also, where do I find the definition for "AVR32_USART1_RXD_0_2_PIN"? I had to play a little bit of hit and miss with the numers before I was able to connect to the usart on its actual pins.
