I have configured the STM32F030 with DMA for RX, and when sending 0x05 from a PC, I observed 0x7d on the debugger. Upon checking HAL_UART_GetError() during reception, it showed HAL_UART_ERROR_FE. I am unsure about the cause of this issue. Could you p...
I'm developing a system with a GMS module, where AT commands are sent to the module via an STM32L0.In this case, I'm having problems with the AT+CSTT command, which was giving me an ERROR. After a lot of thought, I realized that the error was due to ...
I have a design using USART1 on an STM32F3 as a LIN slave receiver using the old standard peripheral drivers from ST Micro. The code is too much to post here, but I have LIN Break Detect and RX Not Empty interrupts enabled, and for some reason under...
If you enable Transmission Complete (TC) interrupt flag TCIE in the UART_CR1 register before enabling UART itself, the interrupt will still be be generated.It is not possible to clear TC flag using USART_ICR TCCF in such state. The interrupt handler ...
On G030 if an overrun occurs on usart2 (no FIFO available) the reception of further bytes stops.Is this intentional or an known error?
Hi, i am using STM32H753z i try to switching FDCAN GPIO is PD0, PD1 to UART tx and rx (same pins)now i changed FDCAN to UART tx side is fine but in Rx side i face issue ( no data is receiving to receive buffer). #define CAN_AFR 0x99 #define ...
Hi i am receive data using UART 4 and transfer same data back like loopback but data is mismatch. same process in stm32f207 is working, #include "main.h" UART_HandleTypeDef huart4; void SystemClock_Config(void); static void MX_GPIO_Init(vo...
I am working on a project that uses STM32F103 and STM32G4 as MCUs. They need to communicate between each other using UART. I am trying to configure STM32F103 UART clocks to match the STM32G4's clocks but I have not been able to figure out where to do...
We get a constant square wave on USART2_TX (PA2) on some of our STM32L451CEU6TR products. This seems to happen sometimes after a power cycle (brown-out). The square wave is a around 32kHz. As mentioned, this only happens on a few of our units, and af...
Hi,I am working with STM32g491re custom board. With UART communication our STM32 and other MCU communicating.After flashing the firmware with debugger both boards are communicating properly but once power off & on If other board sends the data stm32 ...
