STILL A PROBLEM ON THIS ONE.
TRY TO COMPILE YOUR Keyboard Example-IT DOESN'T.

Problem still exists for the (https://github.com/KrisKasprzak/Adafruit_ILI9341_Keypad) which was/is the subject of the posts

Library fixed. I've made some internal changes as well to reduce memory consumption and speed things up. The init for the number pad includes and extra parameter. I would recommend deleted current installs of the ILI9341_t3_Keypad and getting the latest at

https://github.com/KrisKasprzak/ILI9341_t3_Keypad.

Examples updated as well and tested with Teensy 3.2 and Teensy 4.0.

Hello Sir,

I'm currently unable to access the updated version of the library, so I modified the .h file from the existing example provided in the ILI9341_t3_Keypad library. However, I'm facing a couple of issues:

• The keypad layout appears misaligned on the screen.
• The touch detection is inaccurate — for example, when I press 9, it registers as 6, and pressing 5 returns 8, and so on.

Kindly suggest how this can be resolved.

You need to get the latest lib. Amongst some fixes, I've added a routine to calibrate the display touch coordinates.
