Hi, I'm pic and this is my space invader
A frustrating week to get my PIC 16F628A work outside the programmer without external crystal. It finally worked. I got it to blink a led. That should have been like three minutes. After that I was quite prepared to debug every little detail one by one from stamp setup to pic setup. However, just out of curiosity I copied the matrix bit of the code and pasted it into picbasic, changed the pin names and it worked! So the part that was supposed to take the week was done in three minutes.
