Hi,When HAL_Uart_errorhandler is triggered, how can we check if the trigger is for reception or transmission?

Hi,I am using STM32H753ZI nucleo board, developing with Keil IDE. I am using UART RX and TX DMA. I want to check if there is a possibility of corruption of UART data while transmitting with DMA Tx.The sending device will send 8-byte defined command t...

I am using UART Receive DMA in circular mode. I am expecting 8 bytes of data to be received on the UART from another device. Hence, I am using "HAL_UART_Receive_DMA(&UartHandle, (uint8_t *)aRxBuffer, 8)". The problem is when a burst of more than 8 by...

Hi,I am using STM32F779NI and CMSIS RTOS2 for my project. Software was working well till I added code for low power mode with RTOS tick-less operation as per the linkhttps://www.keil.com/pack/doc/CMSIS/RTOS2/html/group__CMSIS__RTOS__KernelCtrl.html#g...

Possible UART errors listed below, and which one is for TX, and which one is for RX mentioned below. Please let me know if my understandings are correct.#define HAL_UART_ERROR_NONE (0x00000000U) /*!< No error */#define HAL_UART_ERROR_PE (0x00000001U)...

Hi,Any findings on the issue

Is the DMA buffer valid during the transfer?How can we know? The status message which is sent is in different global variable at different instances of particular device operation, but it is in global variable and pointer to the variable is hence pas...

How often are you receiving data? The data is not receiving very often. It is based on operations to perform. It is an 8-byte command based on which certain operations are performed and then response is sent back in an 8-byte format.In an operation, ...
