Timeout on usart2 with DMA

Hi everybody,I'm using a STM32L476RG. I use the usart2 to transmit/receive frames from an external sensor. The reception is working with DMA1 channel6 (I use Transfer complete and idle line interrupts), and it works very well.I'd like to add a timeou...

I sent a command with interrupts using HAL_UART_Transmit_IT to get 19 strings. But with interrupts turn on uart2 i am getting half of it not full of 19 strings.

where can I find a description (address, position) of the flash sectors of the STM32G family? The code generated by CUBE only says FLASH_SECTOR_0 etc, and the datasheet does not mention any sectors

Baud rate problem

Hi, I am using STM32F767ZI. I am working on UART communication of STM32F and other MCU. But I have a problem. Other MCU 's baud rate is 125K, 250K and 1M. Do you have any suggestions about this? Thanks to answer.

I concanate two strings using strcat. Then I transmit that strings through uart2 but when I check in the putty terminal the string is showing half of it. It is not showing full string on the putty terminal. Any idea about this?

Problems with receiving from ESP8266 via UART

Hi,since some days I try to get a communication between a STM32F030R8 Nucleo and an ESP8266 WIFI module working. Communication between Putty and WIFI module works already. I am stucking at receiving the answers from ESP module. I already tryed it wit...

Can't access RTC Alarm Registers for second time

Hi STM32F103 ProgrammersI am fighting with my RTC. I have it working but have problems with accessing the Alarm registers for the second time. I can't find the reason why I can't.I program the RTC direct using Bit fields and when needed register bit ...

I am using the STM32L051K8U6 and I have set up to use EXTI interrupt on PA0. I also have EXTI interrupts enabled on PA3, PA10 and PA11. PA3, PA10 and PA11 do generate interrupts but not PA0. I include the MX project. Is there any possible reason for this?
