Hello everyone, Hope you are well.

I have a question about programmation on chipKit 32 I must use UART at low level for my project (CNC driver based on GRBL) To do real time communication I need to intercept uart interrupt on Serial0 (the one used with usb I think). I can't figure which vector I need to configure. What's the difference between UART_1 and UART_1A ? Is there more configuration to do when using Serial0 at low level ?

Thanks in advance.

Intercepting serial reception for a UART interface is as simple as attaching an interrupt routine to the serial object.
