Hello All, I'm trying to wrap my head around the following diagram: https://learn.adafruit.com/assets/14466 https://learn.adafruit.com/capacitive-touch-sensors-on-the-raspberry-pi/wiring What I don't understand is how the out from the sensor is connected to the raspberry pi. It looks like it's going...
Okay, so I've got it all wired together now: Output pins on the Raspberry Pi going directly to the input pins on an Adafruit Atmega32u4 breakout, nothing in-between. I also have a ground pin connected from the Pi to a ground pin of the Atmega32u4. So far it all works... but I've run into a strange i...
Thanks! I'm feeling a bit more confident now! But out of curiosity I have to ask: if I'm only sending on pins from the pi to the micro (in that direction only) then does it still matter if the micro is the 5v version rather than the 3.3v?
Can I wire a pin from the gpio of a raspberry pi to a pin of a sparkfun pro micro (Arduino micro)? If so how? 1) Would I need to connect the ground from the pi to the pro micro? 2) Does it matter which micro I get, the 3.3v or 5v, since I'm only communicating in one way (pi to micro)? I only need to...
First: Awesome thread!!! Second: I've got everything up and running smoothly thanks guys! However, I'd like to be able to capture images with the same quality/field of view that I get out of raspistill, but I end up with poorly exposed, mostly underexposed/dark images. I've tried setting: mmalcam_us...
