software uart pic

Hi,
Im not very good at C, but need to bit bash 0x55 at baud 19200 out of RC5 on my PIC 16F876, My USART is already being used so i can not use that.
Does any one know where i can get a sample C file to do this task for me.
I am not sure of the code required.
Thanks

I don't know of C code, but you can do it in assembler.
Take a look at AN555 from Microchip

Just change the processor type.

Hi!

The most famous and simple C Compiler for PIC microcontroller are CCS.
This c compiler offers some libraries and functions (ANSI and NOT ANSI) for access some microcontroller peripherals. In Your case, You need a simple serial, then You can use #rs232 pre-processor directive and put bytes inside/outside of "world".

For more information about this compiler, visit the site:
