Hi, I am working on a project on the STM32H730 that runs a high priority audio interrupt thread as well as a lower priority asynchronous loop for user interface processing and a 1ms SysTick interrupt for user interface processes that need some accura...

Hi, I am working on a realtime audio DSP product using the STM32H7 with a AS4C4M16SA-7BCN SDRAM chip for long delay line memory. I am using the FMC controller with the settings in the attached photo:The product processes an incoming audio stream in r...

Hi, I am running a debug session for a project and am running into a pretty baffling problem where values I load into an array are seemingly getting erased by a tools error. I have a class that has an array as one of its members, that gets filled wit...

Hi, I am writing a driver for the AD5262 digital potentiometer, which uses SPI type serial but requires a 9 bit data format. I would much rather use the HAL SPI library (which has worked on similar AD family pots) and not use bitbanging. However the ...

Hi, my team works with STM32CubeIDE and shares projects via github. We've been running into somewhat frequent errors where projects settings don't get shared properly when pulling the files down from github. On the flipside, there are a bunch of auto...

I think there is some misunderstanding: the whole idea is that I don't set global_ms with an interrupt, but by checking a timer value which is incrementing independent of the CPU, whether I store global_ms as a variable or look directly at the timer ...

Could the 16-bit timer be reset after reading in order to get an elapsed millisecond value?Would this syntax work? Or is there a function I need to call to reset the timer counter?static uint32_t global_ms = 0; uint32_t elapsed_ms = TIMx->CNT; TIMx...

Are you able to share what the MX configuration for setting up a 1ms timer looks like? As I stated in my last post, the MX UI is unfortunately not very intuitive for how to achieve this. It does not display a clear period or frequency value for the c...

Is there a SysTick->CNT that could be accessed without additional configuration?

Is there an easy way to calculate the frequency or period of the timer? The options CubeMX gives for this are rather limited to say the least:As you can see, I can select between 3 clock sources but there's no indication of what frequencies these are...
