try modifying all TFT SHIELD calData to:
uint16_t calData[5] = { 293, 3547, 243, 3592, 3 };

Hello, I HAVE EXACTLY SAME PROBLEM !
Please HELP ME how can I Fix it and which folder, line and command ?

HELLOO. I FIXED IT !!!
go to here : https://github.com/Bodmer/TFT_eSPI/blob/master/examples/Generic/Touch_calibrate/Touch_calibrate.ino
NEXT step is to Upload that code and calibrate it :D

But ... Idk why IAM NOT ABLE TO COMPILE Arduino esp32 Marauder code from source when I edited ONLY TFT Display uint16_t calData[5] = { Here My Numbers };

error is here :
exit status 1

Compilation error: control reaches end of non-void function [-Werror=return-type]

I need help dude. I just started out and just built the esp32 marauder and I have the same problem, you told us how to fix it but I'm lost. Can you send me a vid or something, maybe even detailed instructions? If you do thank you so much!

Hello Im finally here.
What is your problem ?
What u did and how (i need your steps to help u fix that)

• U MUST have installed esp32 board version 2.0.14 (in Arduino IDE,BTW I Have Arduino IDE v2.3.2)
• then ADD CORRECT LIBRARIES to your Arduino Library folder (where u have all library folders)
• go to C:\Users\YourPCName\AppData\Local\Arduino15\packages\esp32\hardware\esp32\2.0.14
• and there open "platform.txt" file and press on keyboard CTRL F (it will switche to easy search mode)
• then type to search bar this : compiler.c.elf.flags.esp32= and hit ENTER
• then add this : -zmuldefs to end of compiler.c.elf.flags.esp32= (it MUST be like this compiler.c.elf.flags.esp32=-zmuldefs ... and here DO NOT CHANGE ANYTHING)
• hit CTRL S
• then open your downloaded (from that LINK I gave) then open esp32_marauder.ino
• go to TOOLS -> Sellect this : Erase All Sketch Before Upload : "Enabled"
• go to TOOLS -> Partition Scheme: (and here sellect Minimap SPIFFS (1.9MB APP with OTA )
• Sellect board ESP32 Dev Module
• sellect your port for esp32
• Find info about it (there is fixed code in settings.h exactly this line //#define TFT_SHIELD and uncommented #define TFT_DIY inside "configs.h")
• U can directly go here : https://github.com/Fattcat/esp32-marauder

Check IMG

• upload esp32_marauder.ino and it SHOULD now WORKS !!

IF YOU still have lot of problems with uploading code, I can make for you ".bin" file to easily flash without libraries.

• Let me know if something happenned wrongly

Recently I started working on Shark Predator Firmware (more advanced abd hard now to do) this firmware will be able to do lot of types of attacks.

@Fattcat pls make a bin code too hard :(

@casoncure
Hello.
I want to know if u followed my step by step guide (if it was useful or was NOT)

YES, I can make .bin file for you.
I DID IT !
You can now download and flash it from here

• (Just) download .rar file, unpack it to folder, then open that esp32 flasher and pick .bin files that u unpacked
• Follow this photo if u have absolutelly no experiences or skills
• INFO ! it may take 5 - 10 mins to flash (depends on your super fast PC xD)
  
  !
• Let me know
