PIC to PIC communication

I need to send a 18 bit binary number from one pic to another pic of the same type. I am using PIC16F877A. I was wondering if anyone knew of a way to do that without using the serial port. I don't necessarily need to clocks to be syncronized. Is there a way to just send data out of one output pin and into an input pin on the other pic Question

Thanks for your help,
B Very Happy

There is a method given in the CCS FAQ, though I admit I've never
done this.

One could also look at using SPI or IIC serial transfer. Both are readily available standards with minimal hardware.

Serial communication may also be used ( in this case you need not use the MAX 232 IC ).

thanks

Nooooo!, have one PIC with speech synthesis and the other with an "electronic" ear.

The transmitter could speak the number in a human voice and the receiver could listen and recognise this.
