Dear members, I have pasted all my codes.. in the link above The GPIO.h,.c files are 100percent working fine I have checked with other peripheral projects. The delay function also works correctly tested for led blink.. Now I am stuck in LCD program only.. My main aim is to just display 1 character I have gone through datasheet and forums and have taken everyones's suggestion accurately I still can't figure out what's wrong with my program.. I have tried this LCD board for arduino program it works there. Also I have checked voltage specifications and all pin's connected are 5v Tolerant as per stm32 datasheet. Please can someone figure out whta I may be doing wrong.. Your suggestions may help me.. I would be greateful..
