- Sun Oct 02, 2016 7:04 am #55974 I would start with looking at the chip on the TFT pcb. It may use at different chip than the xpt2046. With tft's they can look similar ( same screen size) but the tft controller can vary as well as the touch screen controller.

- Mon Oct 03, 2016 5:49 am #55993 Yes I checked. On both xpt2046 is printed on.

- Mon Oct 03, 2016 8:40 am #55999 I can confirm things work.
It looks like you have the correct controllers for both the TFT and the Touch
Next look at the wiring

Below is the set up I used. The style declares the wiring schema before writing anycode.
[code]
/// notes working 5/27/16 ILI9341 XPT2046
//// LCD 240x320
/// the esp12e USES qio FOR THE PROGRAM FLASH
/// the places GOPI10 and GPIO9 as unavailable
/// unless the flash inside the can is removed and pins 3 and 7 lifted
/// pin 3 is wired to 7 and then to 3.3v
/// pads 3 and 7 are connected to GPIO9 and GPIO10
/// since GPIO9 and GPIO10 are now free and then set the FLASH to DIO mode
//// QIO will now not work
/// DIO mode maybe is the default for the arduino IDE NodeMCU v1 12E board

- Tue Oct 04, 2016 3:36 pm #56066 I don't use the SD card so the GIOP 9&10 aren't connected but all the rest is exactly as in picstart description. - Anyway I don't believe it'^s a wiring problem as the old version works

BTW @picstart: Is the plastic around the pins yellow or black in your case?
