Hello,I've been using the STM32L5 FDCAN HAL Driver but I have some problems with it.When i try sending some CAN 2.0 frames to the STM32, an isr is called and the error Message RAM access failure is raised.Sometimes, the ACK is sent but the interrupt ...
Hello,I am working on SAI part of the NUCLEO-F756ZG board and I observe an issue with the DMA.The configuration is:SAI A as a master with master **** out and audio mode = master receive. SAI B as asynchronous slave and audio mode = slave transmit. (S...
we are using STM32L496ZG NUCLEO Board for development .Timer2 channel 3 (PA2) is Configure for counting.
Hello everyone, I use STM32F103C8 and try to receive data via USART1 using DMA and IDLE. When I receive 1 character and IDLE occur then USART1 interrupt was generated and call "USART1_IRQHandler" function like this.void USART1_IRQHandler(void) { cou...
After detecting a rise edge in interrupt line, I would like to keep a LED on until it detects a falling edge. Do anyone have idea of how to do it?
Hi：STM32F103VBTx STM32CubeMX_v5-3-0The basic code is generated by cube.There are the following changes:static int8_t CDC_Receive_FS(uint8_t* Buf, uint32_t *Len){ /* USER CODE BEGIN 6 */ CDC_rx_len += *Len;//pinjie USBD_CDC_SetRxBuffer(&hUsb...
The application note AN2834 states that this parameter should be listed in the device datasheet. This is true for MCU families like F4, but not for G4. I know that there is a difference between slow and fast channels, but where could I find precise v...
I' using USART1 to send and receive DMA with a module. When I configure DMA for one of TX or RX, it works fine. but when I configure it for both TX and RX, in RX-Buffer I have '\0' character in second position. for example the receive buffer is so:"...
