For a project I am using a number of timers to generate and/or monitor digital signals in a custom protocol. I stumbled upon a glitch in a timer Output Compare channel which I would like to share to find whether this is recognized and if there is a p...

I am a fan of STM32, especially the peripheral sets offered are great. Over the years however, one type of peripheral is missing which would be a great help for many projects, this is a programmable logic cell.Such a cell would contain elements like ...

I am using linked list based DMA with an STM32U5 and everything works as expected, great. I do however have a question what is the best way to set the source address, destination address and length for a linked list node.CubeMX allows these parameter...

I am working with an STM32U575, HAL version 1.5 and found the issue described below(Have checked the HAL code for the H5 and H7 and these contain the same issue)See picture below, when aborting an PSSI transfer, before checking the state on lines 125...

I am working with the MDF peripheral and find this to be a great peripheral. However the CubeMX generated code for multiple DMA based filters is not correct.I am using two filters with DMA and CubeMX generates the following descriptors:MDF_HandleType...

And further investigation learned that it actually was not a wiring issue but a pin issue. The channel showing the glitch is connected to another timer as a trigger. The input pin of this other timer was pin PE5 on a Nucleo board. The nucleo document...

Mea Culpa, Mea Maxima Culpa,I caused noise over some noise but the source of the noise was me.The channel with the glitch is connected to another timer input through a wire. As it seems now, this wire picked up noise causing the glitch.Changed the wi...

Below are the register settings as shown in STM32CubeIDEAlso I use DMA to constantly change the value of CCR3 which is what the DMA Burst statement below is for.The timer starts at 0, when the rising edge is detected the count goes to 1 which matches...

I really love the software ST provides nowadays. I remember the time (not that long ago) that chip manufacturers did offer very limited software support. Their business was selling chips and the programming was left to the customer. Most manufacturer...
