GR-PEACH as an Arduino Drop In


Just wanted to know if PEACH could be used as an Arduino drop in board in my system design. Are there any limitations? Such as libraries and coding.

I tried to port a UNO code over to PEACH running as an Arduino and it can compile without any errors. However the output display did not work as expected ( as seen in the original UNO ). Is there a documentation on the PEACH programming codes?

Thank you.
