I am trying to communicate with a PC through the EDGB virtual serial port (for the purpose of redirecting printf via UART to the PC).
I'm working on keil uVision 5 and debugging with j-link EDU.
in other devices some of the UART was directly connected to the usb port of the board but I think that in ATSAMV71Q21 no.
I have connected the board through the USB DEBUG and I am able to establish the connection with PuTTy and Tera Term (the status LED lights up)
I see in the device documentation the USART1 should be used for this purpose:
I have configured the USAR1 to operate in normal mode, asynchronous mode, 8 data bits, with 1 stop bit and at 9600 baud. I have enabled transmission and configured the corresponding pins (PB04 and PA21) for peripheral functionality and no I/O function.
When I write in the transmission log of USART1 I can't see the transmission in the PC terminal:
can anybody help me?
Thanks in advance
