HAL library 12- LCD for STM32Fxxx

LCD is first big library provided from me. It’s the same as SDRAM, it works on STM32F429-Discovery, STM32F439-EVAL and STM32F7-Discovery boards. With one library you can control 3 boards just by selecting proper define in your target.

Library can be extended to other boards. Library requires FMC peripheral for SDRAM for display memory, DMA2D for fastest graphic accelerations and LTDC for transferring layers to LCD.

Board pinouts

LCD pins are different for different board. Using proper defines (explained below) you can select which board is used.

For full pinout list, download and open LCD library and check header file with description.

Board selection

The most important thing is to tell library, which board is used in target system. There are 2 possible ways to do that. One (and I prefer it) is to check my DISCO library and follow instructions which define you have to set for proper board, and another, explained below.

If you choose option one, then you will have no worries in my future libraries where library needs to know exactly which board is used!

The second option (I don’t prefer it) is, to set define only for this library. Copy define corresponding to your board into defines.h file or make a global defines in compiler’s settings. I made global defines in Keil uVision under “Options for Target” -> “C/C++” tab.
