Hello,I have a general question regarding the linker script generated by STM32CubeIDE.Most of time the STACK and HEAP is placed together into the "same" internal SRAM (see section .user_heap_stack example for demonstration purpose). Note: Yes, there ...

Hello,I would like to know if there is a possibility to readback the MPU confiugration for each configured region? HAL only provides a setter function. If I take a look into the internal implementation, it seems that regions get overwritten, when I ...

Hello,I have a question regarding several timers which are confiugred in PWM input mode (CCR1 is used to measure the PWM period and CCR2 is used to measure the PWM Width). So far when I plug a user signal on the evalution board, I can see the correct...

Hello,I face serveral data coherency issues on my dma buffer which is used to place the values of serveral ADC channels into it. This is executed on M7 contextJust as a reference, I have a dummy project without any MPU configuration and data cache is...

Hello,I am using the ADC1 + DMA to sample 10 analog channels on the CM4 without any MPU config. When I remove any external trigger e.g. 3.3V power source on the analog channel, and I start sampling all 10 channels via the DMA , all values inside the...

Hello,@TDK thanks for the feedback, this is exaactly what I wanted. I tested this approach with minimal SW overhead when taking the flags into account and I am able to reset the frequency parameter to 0 in a simple and determinisitc fashion.@Communi...

Hello TDK,thanks for your answer.What is your assumption in your explaination? Interrupt enabled or not ? In my case, I would like to not use any interrupt overhead for PWM input measurement as I can easily read CCR1 for the period and CCR2 for the w...

Hello Paul,thanks for your feedback.According to that example for TIM2 and TIM3, you use the third channel for the output compare. TIM2 and TIM3 are "advanced timers" which offer more channels to be used due to its internal nature. Is it possible to ...

Hello TDK,1)for the SCB_InvalidateDCache(). it caused once a Hardfault issue. on my sinde and it keeps stucking.Verfifying is done like this: Attach a voltage level e.g. 2.5V on ADC channel 1. When starting the sample procedure, I see that the raw da...

Hello TDK,thanks for the clarification and fast reply. Do you know where I could take a look at for some reference material in order to accelerate the implementation (repo of old ST mcus?). I went through all examples of different STM32H7 platforms ...
