Arduino Nano ESP32 with TFT Touch Screen Display

Hello all,

I am trying to set up an Arduino Nano ESP32 with this TFT Display and am having some issues with the touch screen.

Using the TFT_eSPI library I am able to get the screen to display; the "Colour_Test" example sketch works as expected. However I am not able to get any reading from the touch screen when using the "Test_Touch_Controller" example sketch.

I have wired the TFT pins to the Arduino pins as such:

• VCC => 3.3V
• LED => 3.3V
• GND => GND
• RESET => D7
• DC/RS => D8
• CS => D9
• T_CS => D10
• SD0<MISO> => D12
• T_DO => D12
• SDI<MOSI> => D11
• T_DIN => D11
• SCK => D13
• T_CLK => D13
• T_IRQ is left unused.

My User_Setup.h looks like this:

TFT_eSPI ver = 2.5.34
Processor    = ESP32
Frequency    = 240MHz
Transactions = Yes
Interface    = SPI
Display driver = 9488
Display width  = 320
Display height = 480

MOSI    = GPIO 38
MISO    = GPIO 47
SCK     = GPIO 48
TFT_CS   = GPIO 18
TFT_DC   = GPIO 17
TFT_RST  = GPIO 10
TOUCH_CS = GPIO 21

Font GLCD   loaded
Font 2      loaded
Font 4      loaded
Font 6      loaded
Font 7      loaded
Font 8      loaded
Smooth font enabled

Display SPI frequency = 27.00
Touch SPI frequency   = 2.50

I have also set the "Pin Numbering" setting to "By GPIO number" in the IDE (as seen in this fourm post)

When I run the "Test_Touch_Controller" example sketch, the only output is:

x: 0     y: 0     z: 0 

Is my wiring or settings incorrect? I would appreciate any guidance on this issue!

Thanks,
ZeruT
