Hello!
Does anyone know how to resolve this error?
r: ‘class TFT_eSPI’ has no member named ‘getTouchRawZ’
Serial.printf(“z: %i \n”, tft.getTouchRawZ());
^~~~~~~~~~~~
exit status 1
Compilation error: ‘class TFT_eSPI’ has no member named ‘getTouchRaw’
Hit There,
Nuc.
any chance you have the older or newer lib or can you comment the print out?
Any code also would help see what’s up. I played with the Round display with both libs so,
check out “round Display”

Hi JP!
I have the new lib. I have done the Test_Touch_Controller example from the TFT_eSpi lib (2.5.23).
And the result is:
Compilation error: ‘class TFT_eSPI’ has no member named ‘getTouchRaw’.
Which part should I change in User_Setup.h of TFT_eSPI?
Thank you very much.
Nuc
Hi there,
Nuc
I think the LIB is the issue, “TFT_eSpi lib (2.5.23).”
https://github.com/Bodmer/TFT_eSPI
get the ZIP and Add it to the IDE, remove any others you have.
Is the one I would use , it contains a keyword “getTouchRaw”

so I tried it with my ESP32C2 and round display.
It compiled and runs on my unit. Be sure to read the Header about CS pins etc. for your hardware.
code…
// This sketch is to test the touch controller, nothing is displayed
// on the TFT. The TFT_eSPI library must be configured to suit your
// pins used. Make sure both the touch chip select and the TFT chip
// select are correctly defined to avoid SPI bus contention.
// Make sure you have defined a pin for the touch controller chip
// select line in the user setup file or you will see "no member"
// compile errors for the touch functions!
// It is a support and diagnostic sketch for the TFT_eSPI library:
// https://github.com/Bodmer/TFT_eSPI
// The "raw" (unprocessed) touch sensor outputs are sent to the
// serial port. Touching the screen should show changes to the x, y
// and z values. x and y are raw ADC readings, not pixel coordinates.

Hi. It works! Thanks JP
Hello !
I am using esp32s3 with same display and i am using the above code.
it show me on the serial like below
x: 0 y: 0 z: 0
x: 0 y: 0 z: 0
x: 0 y: 0 z: 0
x: 0 y: 0 z: 0
x: 0 y: 0 z: 0
x: 0 y: 0 z: 0
x: 0 y: 0 z: 0
x: 0 y: 0 z: 0
x: 0 y: 0 z: 0
x: 0 y: 0 z: 0
What should be the reason ?
Hi there,
Yes You should get the X position, Y position, and Z the press strength (how hard or soft you press)
You need the specific Libs for it to work. Either the TFT_eSPI or the GFX with adafruit touch driver.
Check the compiler output for which you are using and READ the Wiki for the “HOW to” portion.

When you get the LIB’s worked out it will work. 
Thank you for your response.
I am using this link Using LVGL and TFT for all XIAO Series | Seeed Studio Wiki for libraries. with thisTFT eSPI version Xiao Round display starts showing x,y,z value zero.
Touch hard and soft press both are not effecting. only showing value 0.
x: 0 y: 0 z: 0
x: 0 y: 0 z: 0
x: 0 y: 0 z: 0
x: 0 y: 0 z: 0
x: 0 y: 0 z: 0
x: 0 y: 0 z: 0
Hi there,
Can you post the compiler output, the first 4 lines and the last 20 b4 the uload.
Did you make the necessary edits? and move the round display file to the libs folder?
