I have a CAN Network with several nodes. Each nodes sends only a ACK when the message was ment for it. Lets say I have nodes A, B and C.Node A wants to send the message with ID 0x5. Node B ignores this message. Node C accepts this message (sends Ack)...
Hello everyone, I'm currently facing a puzzling issue with the Flexible Data-rate Controller Area Network (FDCAN) on the STM32H755ZI board. Despite using the exact same code that works flawlessly on the STM32H753 board, I am unable to get the FDCAN t...
Hi, i am looking for to use FDCAN by using GPDMA . I am using STM32H5 MCU for my application. it is not clear to me how can i use GPDMA with FDCAN. please guide me__PRESENT
Hello all, I am trying to receive CAN frames from a BMS, each frame is sent every 100ms and i am running the MCU's clock frequency at 180MHz (max speed) for Nucleo F446RE. Unfortunately, i am missing some frames randomly and it makes my stateflow n...
void tcpsend (char *data) { // send the data to the connected connection netconn_write(conn, data, strlen(data), NETCONN_COPY); // relaese the semaphore sys_sem_signal(&tcpsem); } // //void HAL_UART_RxCpltCallback(UART_HandleTypeDef *UartHandle) ...
I made a driver for 1-Wire communication using UART in Single Wire Half Duplex mode.The communication is started by sending a RESET pulse that should last 480us. I read that to do it using UART I should set it up to 9600 baud, 8N1, then send 0xf0. Lo...
I understand that ADC Linear Calibration is performed during device production and the values stored in the System Memory.However, I have been unable to find any documentation on where the 6 values are stored.Also, are their 6 values per ADC device (...
I would like to know if it is possible to generate a sweep signal (a sine wave with increasing frequency) using DAC with DIMA transfer and simultaneously sample it by ADC and store these ADC values in memory.To generate the sweep signal, I use TIM2 a...
Dear Sir/Madam,I have already implemented the usb host mass storage class project which mainly mounts the usb disk & writes some data to a given file. But this application is not working. Only usb unmout case is executing even though I am inserting ...
The steps that I had done (STM32F429I-DISC1 Board)1. copy and paste the code into syscalls.c2. edit the _write function4. build the project5. edit the debugger setting6. start debug7. enable the SWV ITM Data Console8. enable the port 0 in SWV9. the s...
