Any one have an any idea Of firmware development of UG96 GPRS module with STM32H743ZI controller

Using ADC1 for very fast readings of IN1 and readings of other channels every 100ms

Hello,I have 7 ADC1 channels that must be read every 100ms. I can't use polling because there are many other tasks being done in the foreground. I can either set up in the interrupt a type of chain in which each time one value is read the next one wi...

ST, please improve learning materials.

Hello,I’d like to offer ST some advice in there educational materials. I’d be willing to work with ST to improve such things if asked.If I’m not mistaken, I think this video is out of date: https://www.youtube.com/watch?v=6RqUkFIeN6wI find it confusi...

Target not halted Error Please Help

Hello friends,The problem is that I use STM32F439ZI chip on my gateway PCB. I also use STLINK V2 to debug codes. While I was debuging my codes I got an error as Target not halted. As for STLINK V2 everything is normal and I connected pins correctly. ...

f_open on SD card returns FR_NO_FILESYSTEM when SCB_EnableDCache() is called

Hi,In my project, I need to use an SD card and also GUI taht requires dcache.I noticed that when SCB_EnableDCache() is called in main(), f_open(..) returns FR_NO_FILESYSTEM.it works normally when it is SCB_EnableDCache() is not called.I suppose I n...

How to do ADC scan-multi channels before run HAL_ADCEx_InjectedStart_IT()

Hi AllI have a problem to do ADC scan-multi channels before run HAL_ADCEx_Injected Start IT().I work on BLDC motor control with FOC. I use Injected ADC mode to read current feedback signal. The ADC read timing is synchronized with the SVPWM signal ...

Resolved! Can the FMAC implement a decimating FIR filter automatically? (can the yet-to-be released STM32U5 FMAC do this)?

If I have a signal sampled at 16384/32768Hertz, but I am only interested in frequencies below 2000Hz - can I use the FMAC to automatically produce a buffer of FIR filtered samples at 4096Hz? I think some hardware filter accelerators have a decimation...
