I am a newbie so thanks in advance for the support.

I am trying to communicate between two pics and I am having trouble finding a solid method for doing this. I am using the latest version of PICBasic pro.

I am using two 16F684 only because I happen to have 10 of them.
If I understand correctly I can't use serin or serout because the 16F684 doesn't support UART. I have been look into the Shiftin in and out but with no luck at all.

My question is, is there any other method to communicate between these two pics or is shiftin and out the only way? Also is there someplace I can find an example of how this would work.
