I would like to do some 'printf' to the display. Is there any tuto somewhere ? or a sample in the keil subdirectories ?
Another point bothers me : abreviations. Is there a dictionnary somewhere ?
Thanks in advance for any advice ...

There's a lot of plumbing, might I suggest cloning and modifying this project. There is code to bring up the screen, and print text,draw circles, etc.

HI,
I found the project and I am studying it.
I need basic informations :
What is the minimum things to do to init the LCD (in this project, they work with SD memory, is it a must ? and what about interrupt ?). I have seen tat we need clock, some pins, ... and what else ? I just want to do a printf("Hello world" for the moment.
I saw layers driven with a uint_32. Is there only a foreground and background or a lot of them ?
The LCD seems to be an array of pixels. But there is a function : BSP_LCD_DisplayStringAtLine. I suppose that the 'line heighth' depends of the font used; but the font is not a parameter of this function !! and what about 'fixed width' characters (font courrier new in W10) and 'variable width' ?
TIA
