pic24f pps
Hi!
Ofcourse it is possible to use these pins for USART. Which pin u want to connect to RX and which on to TX. Reading the datasheet carefully will help u how to do it. I have done that for dsPIC33FJ12MC202. e.g in this processor for the RX pin you have to play with bit0-4 of RPINR18 register. If u want the RX pin to connect with RP15 then the value in the reigster should be RPINR18 = 0x000F and if u want to connect RX pin to RP14 then the value should be RPINR18 = 0x000E;
Becareful to write the proper unlocking sequence to a certain pair of registers mentioned in the data sheet. This is a safety to prevent accidental writes to the configuration registers.
I hope this answers ur question.
If u still don't understand then feel free to ask. Just give me ur controller and desired configuration and i will try to write it for u.
Regards.
