Hi.
I´m using the MAX232 to send information to PC.
I have already had hardware implemented on my protoboard, and I just used it to communicate. I know that I could use the USB of 18F4550.
Like you see on my code, there is a directive to using the serial.
#use rs232(baud=9600,xmit=PIN_C6,rcv=PIN_C7,stop=1,parity=N, bits = 
What I would like is communicate the MF522 using SPI. But nothing happen.
Thanks for now.
