In this document you emulation describes an example LTDC. I solve the problem of using a TFT controller. Besides, all I do is true for the above example.

The project continues to develop on the basis of stm32f429. Writing a function to display the sprite on any background (virtual Layer). Now to deal with the QSPI and record it using information STLink. After that I will carry it on stm32f446. It will also write a function to work with the 29 series of NOR for storing sprites and character generator stm32f429.

Problem with failures when outputting the image removed. It was a bad connector contact RD signal. But this led to a positive result, the code has been optimized so that these failures have little effect on the program.

Disregard of TFT and consider working with xpt2046.

Continuation of work, we connect all of the material into a single project. Start with a small, very simple, button.

Create three new interactive elements. Textbox, checkbox, text. And their work with a touchscreen.

The text of the code is written in C #. Comments are duplicated in English. I think those who are familiar with programming, he will understand what's what. Wrote the functions for the "slider" element. But I ran into a problem. The touchscreen values change very strongly when pressed at the same point. The moving average was not given a result. Who worked with xpt2046, help with advice.
