3 Pic micros communication

[212853]

Hi, does anybody know what is the best way for 3 Pic micros to communicate with each other. I have a 16F877 and 2* 16F870 and I want them to communicate. The 877 is probibly the master and the 870's pobibly the slaves. If you sugest I2C, does you kown where I can get I2C routines for the master and the salve?

Hmm..why people never have a look at the website they using the microcontroller from? (o;

Microchip has a lot of applications for inter-communication:

But you can also use a simpler version of it...even with only 1 line like the old ADB protocol from Apple...(they also used PIC as ADB controller, long time ago when they we're called GE and not Microchip ;o).


Or have a look at Dallas 1-wire protocol....

You can find i2c application in C at wvw.microchipc.com or at CCS compiler.
You can use also 9bit serial communications.
