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...

Hello, @SofLit I would like to measure the voltage on analog pin A0 and A1 simultaneously, using ADC in DMA mode. I configured my ADC settings as SCAN, CONTINUOUS mode to measure continuously the whole group. The DMA is also configured and linked to...

Hello ST community, I am currently programming an ECU system, using f446re nucleo board. Right now i am trying to communicate with BMS using CAN communication. So far, everything has been set: CAN Initialization and start, sending works properly. T...

Hello, I am currently using a Nucleo F446RE board and i am facing problem while trying to read an analog pin using ADC functions. When i start running or debugging the project, i immediately fall down into Hardfault_handler function. I don't know wha...

@SofLit hello again, So , i am facing a problem to display the frame i am supposed to send from CAN_Tx pin in loopback mode. I am using picoscope to display. Here is the function i wrote to configure the Header, and send the data: void CAN_send(v...

Well, BMS means "Battery Management System" (hardware used on battery to send frames on CAN Bus).So, the point is that it is sending frames 0x586; 0x591; 0x587; 0x582; 0x5C0; 0x580 and more of them.The issue is i can receive only a few of them.Each f...

I wan not able to make it work using DMA so i changed to interrupt mode without DMA, thanks

Alright, found the problem, I was using both fifo0 and fifo1 for receiving whereas i had to use only one for all the frames. Don't know how to use both of them svoid HAL_CAN_RxFifo0MsgPendingCallback(CAN_HandleTypeDef *hcan) { HAL_CAN_GetRxMessage(&...

Anyways i just noticed that the frame is sent continuously from the laptop maybe it is the source of the problem. Gonna fix it, thank you very much for your support!

Yes, actuallty i tried to communicate with BMS (directly on battery) but debug mode is not possible in that case so i am using the laptop to simulate the behavior but sending the frames i want, to test my state machine.
