Hello, We have developed an image capturing application successfully based on STM32H7xxxx and OV7725 camera. We are now targeting to port the application to target STM32U5xxxx with the same camera. But it looks the DMA doesn't works as expected. T...
Hello @Imen.D , A side question: RM0440 for G4 says oversampling mode does not support offset. Any change to this position as like the H7 change? Solved: 'H7 ADC offset correction in oversampling mode - STMicroelectronics Community Thank you. SK
Hi,how do I start the USB DFU Bootloader with a STM32C071 Nucleo? I tried it while putting Boot0 to high and pressing reset or do a power cycle but the STM32 DFU does not show up in the device manager. I connected USB to the NUCLEO extra USB port of ...
Can i use UART + DMA ( normal ) + RTO ? I try to add RTO but when activate RTOE bit the DMA buffer stops fills .I take interrupt with active RTOF , stop DMA , but nothing in buffer !? I use stm32H7 with hardware implemented RTO. Can some one to give...
follow-on from: STM32L562: frequency error when outputting LSE via MCO (crystal mode); bypass OK (solved).Hi all,When LSE is configured in crystal mode, I tried probing OSC32_OUT directly with an oscilloscope probe, but I see no visible waveform (it ...
Hi everyone,I’m using an STM32L562 MCU and outputting LSE (32.768 kHz) to MCO for measurement.In LSE crystal mode, I see a large frequency deviation on the oscilloscope (much larger than expected ppm-level error).To rule out the crystal itself, I che...
Hey, I am using the STM32G0B0VET (16MHz HSE) with a virtual com port over USB. The virtual com port is working fine but as a backup I would love to be able to let the user reflash the device. I was thinking of using the DFU for this since then the u...
Hey guys, I'm looking for some suitable HexaSPI PSRAM and also the OctoSPI Flash for the STM32N645 board I am just building.. I cant find the parts used on the DK so do you have a list of supported memories? I need 256Mb PSRAM and will start with a 1...
Hi, I want to go to sleep/stop mode with STM32 and wake on interrupt. After last interrupt it should wait for 10sec and go back to sleep. But I see an edge case where interrupt could occur just before going to sleep/stop mode.How do I handle interrup...
Hi,i have new design that i am migrating to the STM32G071 and having issues with the SPI1 port PB3,PB4,PB5. Changing CPOL and or CPHA during init code do not seem to have any impact, when powered down and restarted.I am seeing 9 clock pulses when se...
