First let me start with an apology, if I have posted this on the wrong forum It may not be a PlatformIO error it may be the library i m using.
I have acquired a couple of 3.5 inch RPi LCD (A) V3 displays. they seem to be rip off’s of the Waveshare product same name. I have managed to get the one working using the excellent TFT_eSPI lib and PlatformIO. I wrote a very simple program to display lines of text, configured the User_Setup.h and low and behold got the text on the screen. Now to extend my knowledge and put the display through its paces I decided to try and run the examples from the library namely 480x320 Touch_controller_Demo and Graph_2. The touch will not down load and gives a compiler error TFT_eSPIhas has no such members calibratetouch, gettouch and settouch. Any help would be much appreciated .

In order to be of any kind of help, we need to see your platformio.ini and exact code you’re running, or a link to it.
Very Impressed with your speed of response I may be a lot slower .ini is

platform = espressif32
board = az-delivery-devkit-v4

upload_port = COM17
src_dir = C:/Users/john/Documents/platformIO/Projects/Outside Lites/.pio/libdeps/az-delivery-devkit-v4/TFT_eSPI/Examples
The code is the example
Code is TFT_SPI/examples/480x320/Touch_Controller_Demo.cpp. If you require any further info please ask. (Not sure how to provide a link so I hope the project directory structure will help if not please advise.)

Why that? The sourcecode should be in the src/ folder of the project, not in its library dependencies, this is very weird. Also you’re pointing to the folder where all examples are and not the one specific example.
There are two libraries there which are not indented by space, this would be an invalid lib deps declaration. Are you sure you’ve copied it directly?
But if you take the time to declare all libraries in lib_deps, why include the whole Arduino library folder, too? You were already on the right track 
Also makes it hard to reproduce for me since I don’t know what you’ve installed in there.
Let me just take a different approach, I’ll come up with the correct, self-contained, platformio.ini that makes this TFT_SPI/examples/480x320/Touch_Controller_Demo.cpp example compile.
Thanks again for your speed.
point One `src_dir = C:/Users ect
It was an attempt to get the example to run in a similar fashion to ASrduino IDE.
point Two ptlatformIO.ini
Sorry bad cut and paste the syntax is correct in the original.
point Three … lib_extra ect
In colloquial English “Belt and Braces” I was trying to correct an error and simply have not removed any redundant? entries. I under stand that you do not know the contents of my …/Arduino/libaries. but that shouldn’t effect a suitable solution.
Your “different approach” seems to be the best steep forward.

Thanks so far, The main problem not compiling was entirely my fault. I should have RTFM comments in one of the header files describe the non compile error and the reason, which is a failure to specify a control pin number. Unfortunately a number of programs that run on my ESP32 when down loaded via the Arduino IDE will not run satisfactorily, in fact not at all when down loaded via PlatformIO. The program is TFT_eSPI examples TFT_Meter_4 from the TFT_eSPI library and my ino file is below

Other programs from the examples also run when down loaded via Arduino IDE but produce the same symptoms when down loaded via PlatformIO. In all cases I have checked the configurable header files and they are correct. Any hint or suggestions would be much appreciated.
How are you configuring the display in the Arduino IDE with the conig files?
By specifying driver files and by mapping IO for SPI .The method is to remove the comment specifiers from #define statements in two header files user_setup.h and user_select_setup.h. The options include
SPI frequency’s, GPIO Numbers, fonts and TFT chip driver files. The same header files are used by the Arduino IDE which does not produce the same problem. I have checked the header files stored with the PlatformIO project with the Arduino library equivalents and they are the same as far as I can see. I should reiterate that I am using the same ESP 32 connected in exactly the same way for both Arduino and PlatformIO down loads and that PlatformIO does not flag any errors and the download indicates success. I have tried limited debugging via Serial.print with little or no sucess. I have ordered a incircuit debugger so I may, when it arrives be able to further diagnose the problem. Thanks for your interest so far. Regards
John
Can you post these exact files here?
Sure The files are very repetitive so I have Cut and Pasted the relevant sections. Should you require the full files they are at GitHub - Bodmer/TFT_eSPI: Arduino and PlatformIO IDE compatible TFT library optimised for the Raspberry Pi Pico (RP2040), STM32, ESP8266 and ESP32 that supports different driver chips.

Hi All,
Seems my small problem is in some way insolvable, Ha Ho lets move on and leave that one in the “Regrets Basket”.
Thanks to all who have tried to help and I hope you have more success helping with the next “Simple problem”
By for Now
John
