Two Pic interface help
hello
Can anyone give me some introduction for interface between two pic microcontroller. I want a pic is for control purpose and other for display and communication. So I intend to use external RAM to store data of control process. Can you give me a way to connect external RAm between two PIC.I don't want to use I2C protocol because I must write I2C slave for my controller. I only want the pic for control is to control,store data and don't run any more.
I'm waiting for any reply
Thank in advance
