I am currently working on the electronic interface for the Raspberry PI 2 for a high school teacher at Arlington Public Schools. The GPIO pin-out diagram of the 40 pin connector has no specific description for pins 29-40. I personally do not have a Raspberry PI 2 yet so I can't test the new pins and would like to rap up the design by the time the kids return to school on 1/2/2016. I have tested the 26 pin version GPIO_GEN0-GPIO_GEN8 and it worked great.
I would like to be able to utilize up to 12 GPIO_GEN input/output pins and designate them as in or out by pin number within Python. Are the new pins 29-40 of the type GPIO_GEN and configurable via Python by pin number?
To make it a little clearer why I need so may pins I am addressing two MC14028B BCD-To-Decimal Decoders and one CD40147B 10 to 4 line Encoder. I only really need 3 of the 4 binary bits for each chip which in total I would need 9 bits dedicated to GPIO_GEN.
