I'm working on David Hunt's Touchscreen Pi Timelapse Controller (https://learn.adafruit.com/touchscreen-pi-timelapse-controller/overview) and have encountered some difficulty in the the hardware section of the instructions. I have a Raspberry Pi B+.
He specifies to connect to GPIO17, but this is being used by the PiTFT Touchscreen, which uses pins 1-26. I don't see another 3.3V power source that is not covered by the touchscreen. Is there a way to connect to GPIO17 with the Touchscreen on, or a way to get the power from another pin?
I'm really new to RasPi, so would appreciate some advice. Thanks!
