STM32U5 PDMtoPCM filter not working
Hello everyone,I am currently attempting to convert PDM data (from a MEMS CMM-4030DT-26354) to PCM data using the libPDMFilter_CM7_IAR_wc32 provided by STM32Cube. However, the results I am obtaining are not as expected. I am expecting a 1000 Hz sine ...
Regarding VOL voltage at various IOL currents
We are using a GPIO pin in STM32H743IIK6 microcontroller in open drain configuration. In datasheet, it is mentioned that Vol = 0.4V at IIO = 8mA and Vol = 1.3V at IIO = 20mA. What will be the Vol voltage at currents higher than 10mA? How does Vol var...
STM32H7RS: How to safely update bootloader from appli?
When the bootloader is updated from the main appli, the start address at reset can be set to the start address of the main application. By this, it is assured that the device can still be started if the bootloader update could not be completed, e.g. ...

SCB_EnableDCache is stuck
HiI'm using STM32H753 and I enabled the icache and dcache , generated the code , and run it.The function SCB_EnabIeICache() ends but SCB_EnabIeDCache() is stuck.The project is an empty one.What can be the cause of it ?Thanks!
Resolved! STM32F4 Timer Period Discrepancy
I am setting up Timer 1 channel 3 on the STM32F4. I am looking to set up a period of 3.9ms or 256kHz. I am using ABP1 - 168kHz, the ARR is set to 65535, and a prescaler of 10. 65535 / ( 168,000,000 / 10) = 3.9msMy timer initialization is below. _t...
STM32H747 ADC reading isuue
Hi STM team,We are using stm32h747, with CM7 we are reading ADC value in polling mode, when source is not conneted still we are reading 0.5 to 1.8 volts, when the temperature increases from 40 C to 60 C this ADC voltage reading increase with rise in ...
