Hi
i have got a project using two pic16f690 micro controller so i need some one
to help me how to connect between two micro controllers.

Hi,

You can communicate two microcontroller with the help of communication protocols.
Basically in almost all microcontroller is having inbuilt SPI (Serial Peripheral Interface) & I2C protocols.
So just check it out the communication protocols in your microcontroller.

thanks for your replay.
ya i have connected VDD to VDD and VSS to VSS and four LED's also to I/O PORTA RA0,RA1,RA2,RA3. each micro controller to each I/O PORTA. so can i connect the two PORTA's to each other?or just i leave the two PORTA's as it is?
regards

Try to read the data sheet from microcontroller for SPI protocols in Master & slave mode you will learn so many things.
