PICAXE 28x2 Question
May 10, 2011
I'm working on a project and I plan to get the PICAXE project board that is in the "Start Here" tutorial. I was looking at getting the 28x2 microcontroller instead of the 28x1.
The x2 says it has 20 I/O pins instead of specific pins for input and output.
How do I tell a pin to be used for input or output, is that in the programming or is it hardware. And would this work with the project board, or am I stuck with the same I/O pins that the 28x1 has.
