STM32F4 DMA Interrupt big latency :(
I’m having a similar problem. I have two routines running, one using DMA2D to display bitmaps on the LCD and the other a simple timer that toggles LED2 every second. I have run this code through a different IDE and STM32 and in the case of the STM32, it runs at a distinctly slower pace. In fact, the display doesn’t run at all if I have any level of optimisation turned on, and only works when optimisations are turned off.
This is not a code issue as the LED is toggled precisely at 1s intervals in all configurations on all IDEs. So the underlying code is working but for some reason STM32W is causing my code to run in a non-optimal fashion. I’ve tried searching through the forum without luck. Any help will be appreciated.
