1. Create project for Cubemx or CubeIDE

• setting the RCC (Crystal/ceramic resonator)
• setting the debug (SYS / serial wire or trace assyn sw)
• setting the timebase source (i like the basic timer for this)
• if FSMC : setting the FSMC (chip select, memory type = LCD, Lcd reg select, data = 8 or 16 bits, timing)
• if SDCARD : setting the SDIO mode, enable the FATFS, FATFS: USE_LFN, MAX_SS = 4096, FS_LOCK = 5, RTC enabled
• if USB pendrive : setting the USB host, setting the USB power, enable the FATFS, USE_LFN, MAX_SS = 4096, FS_LOCK = 5
• if JPG : enabled the LIBJPEG
• setting the clock configuration
• project settings: project name, toolchain = truestudio, stack size = 0x800
• generate source code

2. Truestudio or CubeIDE

• open projects from file system (only Truestudio)
• open main.c
• add USER CODE BEGIN PFP: void mainApp(void);
• add USER CODE BEGIN WHILE: mainApp();
• open main.h
• add USER CODE BEGIN Includes (#include "stm32f1xx_hal.h" or #include "stm32f4xx_hal.h" or ...)
• add 2 new folder for Src folder (App, Lcd)
• copy file(s) from App/... to App
• copy 4 or 7 files from Drivers to Lcd (lcd.h, bmp.h, stm32_adafruit_lcd.h / c, if touch: ts.h, stm32_adafruit_ts.h / c)
• copy Fonts folder to Lcd folder
• copy io driver to Lcd folder (lcd_io_...h / c or lcdts_io...h / c or...)
• copy lcd driver to Lcd folder (st7735.h / c or ili9325.h /c or...)
• if printf to SWO : copy syscalls.c to Src folder
• setting the configuration the io driver header file (pin settings, speed settings etc...)
• setting the LCD configuration (orientation, touchscreen)
• add include path : Src/Lcd
• setting the compile options (Enable paralell build, optimalization)
• compile, run ...
