Hi everyone,I am trying to setup DCMIPP Pipe0 to read data from 256x192 pixel sensor by 16 data lines.Seems everything configured and working fine except of transfer data to destination buffer.DCMIPP frame counter is increasing. Pipe0 dump counter is...
Hello STM community,I have built and assembled a custom PCB board with an STM32U083CC on it. I have made 5 boards, after the first two did not work, I only populated the minimum on the other three. However, I am unable to debug or event connect to it...
Hi Team,We are using STM32G431RBT6, we have tested the ADC1 for PA3 i.e. Channel4 with external Vref 3.3 and VDDA 3.3 with 12-bit selection and the reading we are getting with 5 to 10 counts fluctuations we are seeing but when we have changed to inte...
Hi everyone,I'm currently designing a custom board based on the STM32F722, and I came across something I need clarification on.According to the STM32F722 datasheet, there is no device listed in the UFBGA176+25 package. However, when searching online ...
Hi everyone,I have a program with UART communication using interruption and SPI communication using DMA. I realized that when I send a lot of data through SPI, sometimes I get the DMA error code in UART, but I didn't enable DMA in serial. As far as I...
Hi all. I have encountered one ADC sampling problem in STM32H743. When the signal's amplitude is large, the ADC works fine. However, when the signal's amplitude is low, there are many jitters that I don't want. What happens here? How to fix it? Many ...
I am using output compare with TIM3 on a STM32H755 I am able to use Output Compare to generate a single pulse on pin PC7 using TIM3, Channel 2.I am using Active Level on Match.I call HAL_TIM_OC_Start(&htim3, TIM_CHANNEL_2) onceAfter 0.5s, it detects ...
I am working on a custom board and I have noticed that whenever the device resets, it becomes unresponsive.The reset causes that hang the microcontroller:Calling NVIC_SystemReset from firmwareHaving firmware stuck and receiving a signal from IWDGManu...
Hi All,I have a system with 2 SPI masters and a single slave very similar to this post from 2014:https://community.st.com/t5/stm32-mcus-products/spi-multi-master-mode-with-stm32f050/td-p/502107What I would like to do is to temporarily isolate the STM...
I have a custom designed PCB board where I have used STM32L56 and W25Q256 along with other components. First, I was using SPI for interfacing but it was taking so much time when writing/reading MBs file. So I have to opt for QSPI now. L5 doesn't have...
