Hi all,I used long time STM32F103 and there was the possibilty to release the CAN Fifo by writing CAN_RF0R, resp. CAN_RF1R register. For G474 I didn't find this possibilty. Has someone any idea how to release the receive buffer or is the only option ...

HiI have been using stm32u585QII3 MCU in our custom board. I am using USART1(PB6, PG10) to transmit and receive data. In interrupt mode transmit call back is working but receive call back was not working. Initially i have set a break point, the inter...
I start a new project using STM32CubeIDE Version: 1.14.1 and select STM32L052K6T6.All I change is the MSI_RC clock setting to be 65.536kHz. This causes all the other clocks to change to this same freq.I program the device and step through - executio...
Sorry if this is a rookie question. I have set up USART 2 to receive a UART command. If the sent command is "<EN>", I need to toggle the value of a global state variable. When transmitting the received data via the callback interrupt, I have no issue...
I am trying to implement MODBUS protocol. STM32 receives an initial message of 8 bytes and then send a response of 8 bytes. However, the next message received by the STM32 doesn't trigger the HAL_UART_Receive_IT callback. uint8_t reception_complete =...
Hi,I need to create a USB composite device class interface with STM32U5A5 controller. I have been using the USB_CDC_ACM example project so far for my development. In this example the USB CDC ACM class is configured and I need to change/add this to a ...
Hello, Does the STM32H755ZIT support flashing over CAN? The application note AN2606 suggests that the H75x series does support bootloader access on the FDCAN1 interface, but specifies pins PH13 and PH14, which are not available on the LQFP144 package...
Hi,What is the effect of "VoltageRange " while erasing a sector ? Er.VoltageRange = FLASH_VOLTAGE_RANGE_1; Ret = HAL_FLASHEx_Erase(&Er, &SectorError); #define FLASH_VOLTAGE_RANGE_1 0x00000000U /*!< Flash program/erase by 8 bits */ #define FLASH_VO...
Hello everyone,I work on a demonstration product using a NUCLEO H743ZI2 board has a main board. I use two timer (TIM3 and TIM2) in encoder mode to measure the speed of two motors with precision.But I didn't manage to get the theoretical results on 1 ...
