Resolved! Does stm32f4 or h7 have DSP hardware implementation?

Hey guys.There is a library named cmsis_dsp for these mcus but when i took a look inside them there were just simple codes and not hardware implementation of dsp.But in datasheet it says:The STM32F405xx and STM32F407xx family is based on the high-per...

Resolved! D-shot with STM32F765: timer + pwm + dma

Hi all,I have a STM32F765, which i want to use to generate 4 D-shot signals on 4 GPIO, in the specific 4 gpio connected to Timer 1 .The timer is set as 4 channel pwm with DMA (memory to perpheral).The issue is that i'm able to generate the desired si...

Resolved! How to receive UART data STM32F103 using interrupt mode?

I am using STM32CubeIDE with a STM32F103 and have UART1 setup in interrupt mode. Is there a working code example anywhere that tells how to implement UART interrupt mode? I have been unable to find via g~~gle. I have worked with multiple other proces...

Sample Capture Only on External Trigger

Hi:Is is possible to configure the LSM6DSOX to only capture data (Accel and Gyro) when an external trigger is given? This would be an interrupt from a host processor. The trigger may or may not be a fixed consistent frequency. I am aware of the DEN t...

ADC of STM jumping over value's

So I’m trying to sample 2 analogue signals with the use of DMA. The ADC’s are running on highest possible speeds (core clock). But when I’m looking at the results for some reason one ADC avoid some “lines�? of value’s and instead of giving the right ...
