| Software Serial Similar to Arduino |

Hi there,
I was wondering if there are any drivers or methods to efficiently create a software serial on a PIC similar to the one the Arduino is capable of:
http://www.arduino.cc/en/Tutorial/SoftwareSerial
This would allow me to use more than just one serial device on a PIC. I could potentially communicate to a computer and comunicate to another pic via the same chip! Or is there another method to implement more than on serial device on a single PIC chip?
Thanks all!

Sure, since you are using the CCS compiler just look up "#use rs232" in the compiler's documentation. That will tell you how to setup software serial. You can set the RX and TX pins and all that good stuff. |

That code doesn't look like anything special. It doesn't use interrupts.
It uses software timing loops. CCS can do that. Just specify two
ordinary i/o pins in your #use rs232() statement. CCS will create a
software UART on those pins. |

| Code: | | #use rs232(baud=9600,rcv=PIN_C7,xmit=PIN_C6) |
In that case PIN_C7 and C6 are the real serial hardware pins. Choose the one you want.

Wow thanks so much guys!
This is another reason I want to try to stick with CCS vs go towards Arduino.
CCS has such a great database of information, especially on this forum! Arduino definitely has this support as well, but the end product with CCS and a PIC for some reason seems a little more professional.
Anyways!
Thanks all!
