Go to microchip.com and look at their sample program. They give free samples!

thought I already mentioned that. lol

Yup, but when the high cost was mentioned I figured it needed said again.

Hi, my electronic teacher has suggested me to connect 2 pic's together but i don't have a clue how to. Can someone help me please

You can hook two PICs together with some sort of serial communication but again for a first project I would not recommend.

The basic idea is to send a command from PIC#1 to PIC#2. When PIC#2 receives a command it will execute an operation. The manual tells how to get started with serial comms.

Have you blinked a LED with one chip yet?

Yes i want control over around 16 L.E.Ds but i cannot find a pic with 16 outputs so i thought connecting 2 pic together would be a better solution. Which command should i send from pic 1 to pic 2?
Thanks

Marty,

For your first project I strongly recommend using just one chip. There are plent of PICs with 16 and more IOs.

The 16F877A-I/P would be a good one to start with. At least I like it. 33 I/Os.

But if you look here you can find others. Just make sure your programmer will support it. And get something in the "F" , 16Fxxxx. These are flash memory.

If you still want to use two the send part would look something like this.

SEROUT PORTC.4,T2400,[9,3] '9 is the character the receiving
                                           PIC is waiting for, 3  is the command

The receiving code

SERIN PORTC.4,T2400,[9],net  'when  9  is received  the  next  
                                   character  is  written  to  variable  "net"

IF net = 3 THEN Do something

Here is a simple example of how to control more LEDs than you have pins.

Hi, i want to buy the micro controller - pic 28x but i don't know its code name (e.g. PIC 16F87X) can anyone tell me its name please?
Also i need to programme my pic after i've purchased it but i can't find any resources to help me learn to programme it. Can anyone suggest a good source which could help me pleasE?

Thank you very much!
