Can't get adafruit HUZZAH esp8266 to display anything on tft touchscreen shield

Other Hardware Displays

Hello all,

I'm working on a IoT project. I was using a mega in combination with a esp8266, but now, because of cost-efficiency, I want to put the whole project on my esp. The esp8266 is working fine and I can program it via Arduino IDE and an arduino uno without the 328 chip. I uploaded the ili9341 graphics test on the esp. The esp is putting stuff on the serial monitor, but the display stays white. My wiring: pin 13 from the screen (clk) to GPIO 14, pin 12 (mosi) unconnected or to gpio 12, pin 11(miso) to gpio 13, cs to GPIO 15 and dc to GPIO 2. I use the arduino uno to power my esp and the mega to power my screen, but in the final product everything will be powered by a 3 amp 220v to 5v converter. This is the code snippet I changed:

// For the Adafruit shield, these are the default.
#define TFT_DC 4
#define TFT_CS 8

// Use hardware SPI (on Uno, #13, #12, #11) and the above for CS/DC
//Adafruit_ILI9341 tft = Adafruit_ILI9341(TFT_CS, TFT_DC);
// If using the breakout, change pins as desired
Adafruit_ILI9341 tft = Adafruit_ILI9341(TFT_CS, TFT_DC, 7, 5, 6);

Are you saying what you want to write to the TFT shows up on the Serial Monitor but not on the TFT?
Without code, we have no idea what you are doing.

I'm using the default ili9341 graphics test, but the code is too long to upload.

Fixed that problem (I had to use the tft-espi library), but now my touchscreen does'nt work. I can't find a library for esp8266 that uses the stmpe610 driver. How do I get this to work?

I'd contact Adafruit on their forum and see if they have a suggestion.

The Adafruit library should work OK for the ESP8266, read about it here.

Thanks! It is indeed possible. I managed to get it working now. I edited the library to use the touchscreen cs. I edited it to 2 first, because gpio4 (my ts cs) is pin 2. But after changing it to 4 it works!
