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 ...
I am working on STM32H723, I use STM32CubeMX and pack FW_H7 V1.10.0 to auto create code. I used 9 uarts, each have DMA for RX, and RXbuffer size if 512. I send data to each uart port 256 bytes one time. Then, the first time, uart report it received 2...
Hi, after having used HAL_UART_Transmit_DMA is there a way to know if all data were been sent by polling something, in order to not use the callback?
Hello everyone,I am trying to create a CAN project with STM32G431C8 . But there is no data in CANTX pin.I created init codes with CubeMX and codes are below.Here is main function;/** * @brief The application entry point. * @retval int */ int m...
Okay, thread number 371982 about the STM's UART... - but maybe not?I recently found that I'm using some blocking printf / UART version, so I wanted to change that to non-blocking via DMA.So far so good, works flawlessly.Until I start "firing" the pri...
