Has anyone gotten the buttons to work on the SainSmart 3.2" TFT screens for Raspberry Pi? I have some ideas to make them call commands or Python scripts, but don't have any documentation from SainSmart as to how they work, such as which GPIO pins they are mapped to. I suppose I could experiment and find out, but that's why I'm asking the forum first.
- Raspberry Pi 2
- SainSmart 3.2" TFT LCD Module 320*240 Touch Screen Display for Raspberry Pi SKU:20-111-971
We can see the buttons on the right side of the module here.
Idea--what if I just ran
./pintest on this after hitting a few buttons? After all, it's plugged right into the GPIOs.
