Hi all, how are you?. I'm doing a project with a STM32F103C6 (it has 32KB flash) and I had to activate optimization options to not run out of memory, right now the optimization options is -Og. After activate optimization a function that I have to kn...
Hi, I am facing an problems that I have never seen before with local variables being allocated at the same addresses of global ones. In the attached image I show an example of a local variable with the address of another variable in the STEmwin libra...
Hi,I want to configure the FMC such, that it should just write 8 data bits in a VERY SIMPLE way - without any switching.I use the following code:#define RAM_D1_FMC_SRAM3(off) __attribute((at(0x68000000+off))) //global variables: int iDebugFMC; int ...
Hello, I'm looking to use Timer and DMA to drive a WS2812B LED with a STM32H7. TIM8 Ch2 is connected to the LED. I would like to explain what I understand so that its clear and I can get it working.A half word transfer from a memory location to the C...
