I made a driver for 1-Wire communication using UART in Single Wire Half Duplex mode.The communication is started by sending a RESET pulse that should last 480us. I read that to do it using UART I should set it up to 9600 baud, 8N1, then send 0xf0. Lo...
I am currently working on a project that involves integrating USB functionality for data transfer and data logging on an STM32F407VG micro-controller. Specifically, I want to log data files on an SD card and enable the user to download these logged f...
Hi, I want to use UART with DMA on my STM32F407 MCU. I would expect that it would trigger `HAL_UART_TxCpltCallback` interrupt on transfer complete, but it does not do that. I tried many different configurations in STM32CubeMX:enabling "USART2 global ...
Hello, I have an STM32L476G Evaluation board, and I'm trying to use USART1 to generate an interrupt on receiving characters. On the evaluation board, this is connected to the RS232 port, which I have a module, I transmit data to get a response back. ...

Hi,I am trying to receive data (on STM32L083) via USART1, the way I was used to doing it on STM32L071. Specifically, I used a circular buffer that was continuously written to by DMA - RX. Now, I've ported the code to this L083 and it seems that nothi...
Is USART1 on APB1 (AN5593, tab.17) or APB2 (DS, RM, CubeMX) and USART2 on APB1 (DS, RM, CubeMX) or APB2 (AN5593, tab.17)? Guess, there is an issue in an5593-how-to-use-the-gpdma-for-stm32u5-series-microcontrollers-stmicroelectronics Rv.4 , isn‘t it?
Hello forum and devs!Have one simple question: datasheet of STM32F407ZGT (STM32F40x series) and Cube MX says me, that this MCU doesn't contain USART6_CTS pin, but contain two USART6_CK pins. Is it mistake, and where is USART6_CTS pin?Official datashe...
I am using stm32u575zit6q. I set Baud Rate 2500000bit/s.(my equipment is only support 2500000bits)usart write is work successful, but read is not.usart read work only 9600bit/s.How do I use the read to work over 9600baud rate?
I created a custom board with the STM32 (F103C8T6), and I am trying to program it using a FTDI USB to Serial module. However, nothing is happening, it doesn't seem to be sending anything and when I try using STM32CubeProgrammer it says:Timeout error ...
Hello there!I've been setting up the UART peripheral on my STM32H5 and everything works great! However, there is one thing I can't completely understand:Using an RTOS to call HAL_UART_Transmit or HAL_UART_Transmit_IT, what's the advantage of one over...
