I am trying to move some some working "domestic" DSP routines to the CMSIS library in hopes of them executing faster. The first one is a fairly simple 64-tap FIR filter on 160 samples of 16-bit fixed point data. I generated it using the Tfilter web...

I just spent several days (luckily not full time) failing to get a simple PWM output working. I could get it working using the HAL drivers, but not able to get it working with the LL drivers. After spending most of my time assuming it was user erro...

I see lots of posts with folk struggling to get code into ITCM, but not the (sorta) problem I have after getting things working. It is just a compiler warning, but I'd like to find an elegant way of handling it.The issue is I am using memcpy to copy...

OK, it looks like it was two different issues clouding things.1) On a lark I just used the single precision floating point CMSIS library, realizing I didn't really know what the library without "fp" in the name really was. Using that library instead...

TDK:Yes, I started down that path, trying to use HAL_TIM_Base_Start_DMA() then some of the macros to enable PWM mode. HAL drivers are pretty complex being very general purpose and I quickly realized that poking at them without understanding them was...

TDK:Ah! OK, it is kinda user error then. I know LL means you take care of a lot of the details and I rely heavily on the examples to make sure I don't miss anything. I see now that the example code I was using as a reference wasn't for an advanced ...

Sarra.S:Just in case it matters, I'm using the STM32G0316-DISCO board and used it as the starting point for the project. will

Thanks for replying Sarra.S!The full part number I'm generating for is the STM32G031J6. It is CubeIDE 1.16.0 (yep, just noticed I'm one revision behind).Here is the TIM17 code generated by CubeMX:static void MX_TIM17_Init(void){/* USER CODE BEGIN TI...
