1. Create project for Cubemx or CubeIDE
2. setting the RCC (Crystal/ceramic resonator)
3. setting the debug (SYS / serial wire or trace assyn sw)
4. setting the timebase source (i like the basic timer for this)
5. if FSMC : setting the FSMC (chip select, memory type = LCD, Lcd reg select, data = 8 or 16 bits, timing)
6. if SDCARD : setting the SDIO mode, enable the FATFS, FATFS: USELFN, MAXSS = 4096, FS_LOCK = 5, RTC enabled
7. if USB pendrive : setting the USB host, setting the USB power, enable the FATFS, USELFN, MAXSS = 4096, FS_LOCK = 5
8. if JPG : enabled the LIBJPEG
9. setting the clock configuration
10. project settings: project name, toolchain = truestudio, stack size = 0x800
11. generate source code
12. Truestudio or CubeIDE
13. open projects from file system (only Truestudio)
14. open main.c
15. add USER CODE BEGIN PFP: void mainApp(void);
16. add USER CODE BEGIN WHILE: mainApp();
17. open main.h
18. add USER CODE BEGIN Includes (#include "stm32f1xxhal.h" or #include "stm32f4xxhal.h" or ...)
19. add 2 new folder for Src folder (App, Lcd)
20. copy file(s) from App/... to App
21. copy 4 or 7 files from Drivers to Lcd (lcd.h, bmp.h, stm32adafruitlcd.h / c, if touch: ts.h, stm32adafruitts.h / c)
22. copy Fonts folder to Lcd folder
23. copy io driver to Lcd folder (lcdio...h / c or lcdts_io...h / c or...)
24. copy lcd driver to Lcd folder (st7735.h / c or ili9325.h /c or...)
25. if printf to SWO : copy syscalls.c to Src folder
26. setting the configuration the io driver header file (pin settings, speed settings etc...)
27. setting the LCD configuration (orientation, touchscreen)
28. add include path : Src/Lcd
29. setting the compile options (Enable paralell build, optimalization)
30. compile, run ...
