I am using STM32h753XI.The MCU uses 2 SPI channels (SPI1 and SPI2) in slave receive mode.The MCU uses 2 DMAs channels (DMA1 stream0 and DMA2 stream0) to read the data from SPI1 and SPI2 and write it to SRAM1 and SRAM2 respectively.The input SPI sclk ...
We have seen PVD triggers when there is transient load of 1A added on the 3.3Vdc (loaded additional to our design through electronic load) and it triggers when the transient load dips the 3.3V for duration of ~450 micro seconds.We have seen BOR trigg...
Hi there!I need your help before i became crazy. I configurate (with DMA) 9 ADC input plus one for Vrefint channel of my STM32F051 discovery, Now my problem:i read a wrong value of Vrefint channel the value is equal a Ing1. But if i configure ony Vr...
Hi,I write the firmware using STM32L432 (NucleoL432-KC) used usart1 and usart2 with DMA RX/TX and received idle line.The usart1 and usart2 using pin of the same port (PORT-A)The problem is lost receive data if I receive data on both port at the same ...
I am searching for a schematic of the STM32L476RG Board. Can anyone help me, where to find it?I searched herehttps://www.st.com/en/evaluation-tools/nucleo-l476rg.html#documentation

Hello,I am using the STM32L071 with the latest STM32 studio software. I cannot find any sign of the VREFBUF configuration in the libraries (I need to enable the internal voltage reference for the COMP1 peripheral). I have found this article for H7 de...
Hello,I'm planning to use a STM32L476 to acquire approx 150 analog signals. For some reasons, I have to periodically check the justness of the ADCs.I read in the RM that it is possible to connect internally DAC to ADC but I can not figure out how to ...
