Hello,

I want to communicate between two pic chip. I would like to know which command to use that create the most stable and reliable wired connection.
I am not sure which one to use between Serout, Serout2, Hserout, I2C ...

Can somebody suggest me one, and possibly the receiving pic can send back a validation number to confirm it has received all the information.
Also does someone has an example of this ?
thanks

K
