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.

You mean this: https://www.st.com/en/evaluation-tools/stm32f7508-dk.html ?

It's an ST product - so the place to start is always the Product Page on ST's site:

In general, or specific to ST ?
ST's terms will be defined in ST's documentation;
For General terms, google should work, or a dictionary of electronics and/or computing
eg, https://en.wikipedia.org/wiki/Glossary_of_electrical_and_electronics_engineering
Hi Andy,
I had hard work last weeks teaching C language to ST people. On a sideway, I asked them on wich microcontroler there are going to work with (they drive machines to build wafers if you understand). They answered : " Arduino" !!!!!!
My problem with abreviation is about ST. I have to understand english and then sentences like
"/* DeInit the LTDC MSP :"
I know what init is; it's the first time I see that we can do a deinit
I know what LCD is, but what is LTDC ? And MSP ?
it would be good if, at the begining of each file (.c and .h) we have a dictionary like
/* LCD = Liquid Crystal Dysplay
LTDC = ...
and so on
but now teaching is over and I'll have some time to understand all that ...
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
