@Question, you need to add the touch screen CS line between an pin of the Photon and D8 on the display board. Make sure to change TouhTest.ino to the Photon pin you chose.

Yay! I did it! I changed the code so that it is “#define STMPE_CS D6” and swapped from the original which was “#define STMPE_CS D5”. Then I connected my D8 TFT touch shield to my D6 photon pin. Once I opened my serial monitor and pressed any key, it told me the resistance (how hard I pushed) and the location. The other error I got was just because “#include” was spelled wrong. Thanks for the help!

I guess this is what I told you in the other thread about TS CS #8 on the silk screen, remember?

Connecting Adafruit 2.8" TFT Touch Shield to a Photon

That link clearly states and on the board you see a silk note TS CS #8 - that’s the SPI chip select for the touch screen. So you only need one extra pin to control the CS pin on the display to actually talk to the touch controler. Here yo can find the wiring info for TFT, resistive TouchScreen & SD Note that the first three pins are always the same (SPI CLK, MOSI, MISO), only the CS pins need to be seperate (and the TFT also wants a D/C pin).

[Question]

@ScruffR Yeah, your right. I totally forgot :P. Still need to change my code from adruino to Photon but after that, I should be done. Thanks for the help everyone!
