Arduino for STM32

I did this work 2 years ago, found example code somewhere in STM codebase and then adapted to the specific memory chip, details long forgotten. The main difference from your code is I dont use the HAL and configuration structures but direct register calls. GPIO pin configuration seems same but here ...

Yes the external SDRAM on the STM32F746 can be be used. * First the memory must be initialized * Second, add this memory in the linker script for this variant /* Specify the memory areas */ MEMORY { RAM (xrw) : ORIGIN = 0x20010000, LENGTH = 320K FLASH (rx) : ORIGIN = 0x8000000, LENGTH = 1024K SDRAM ...

If you want D_CACHE enabled the screen buffer can be cleared in the cache using

I am a retired mathematician using some spare time to play with microprocessors. I have previously been involved in building and programming robot mannequins for artistic exhibitions. Now I am more focused on digital music, and I would like to make the STM32f746 DISCO into a useable platform, and ma...
