Hi,
First of all a very Happy New Year to all, especially the locals that have helped me out so much last year!
I'm thinking of using a 40x1 to control a robotic arm. No problem with the hardware - its the programming I find tricky.
Last code I used port b or PinB's for the first time. I take it on the 40 it just includes C so you write to PinA. PinB. or PinC.
There are 32 I/O .... 9 - 17 x I vs 16 - 23 x O
I've looked at datasheet, Pinout etc, but am not clear on which pins on the chip can be reassigned? All or are some not? Are outputs 0 - 7 (chip pins 33 to 40) reassignable as they are labeled output only on diagram.
Many thanks for any advice
