SW4STM32 and SW4Linux fully supports the STM32MP1 asymmetric multicore Cortex/A7+M4 MPUs

   With System Workbench for Linux, Embedded Linux on the STM32MP1 family of MPUs from ST was never as simple to build and maintain, even for newcomers in the Linux world.
And, if you install System Workbench for Linux in System Workbench for STM32 you can seamlessly develop and debug asymmetric applications running partly on Linux, partly on the Cortex-M4.
You can get more information from the ac6-tools website and download two short videos (registration required) highlighting:

System Workbench for STM32


DAC output "bad resolution"

Hi!
(Sorry if this is the wrong forum. The ST community is down for a few days and I really need help on this)

I’m working on the ADC and DAC on my f413zh board.
My goal is to send a signal trough the ADC with DMA, process the signal with a FIR filter from cmsis (lowpass) and send it out trough the DAC again for measuring.
So far I’ve managed to do this and the FIR is working correctly. However I have troubles with the output signal as soon as the input signal exceeds 1Khz.

The output on the DAC become more and more “blocky” as I increase the frequenzy on the input and above 1Khz it becomes too unreadable, see the attached images.
Im probably missing something obvious somewhere but I cant figure out what to do? I guess this has something to do with sampling/clock speed?

263 hz:
263hz

659 hz:

1.11 Khz:
1.11khz
