need two serial port in one pic microcontroller .....

microcontroller 2 serial port

im using 20MHZ XTL is taht ok ??

For an 18F with PLL a 10MHz would be better if it's speed you're after. That will run the PIC at 40MHz its maximum speed.

Re: pic dual usart

Do you need hardware UART or You could do with one hardware and one software driven port?
I have successfully used two GPIOs for UART purposes with software driver and it is working nice. :wink:

please suggest me how can we make a software diriven port?

I want three serial port in my system, at different baud rate for this
I am using PIC18f452 with 16c654 (quad uart ic)
i m having problem in initializing 16c654 . (bcz of too many register settings)
can any one help me or share some code to initialize ths ic
