Hello everyone, I have recently faced a problem concerning the debugger when trying to flash F446RE board.When i launch the debug mode, the progress bar stops at 97% and doesn't return any error message as output.The problem did not exist before the ...

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...

I could use the exact same configuration and program a few weeks ago.The problem you do not understand is that a line which does a = b; results in a = c; (insted of a being equal to b).This problem has never happened before, and is happening right no...

Well, the tranceiver i am using is a MCP2551: A battery management system, an engine, a cluster, and a DC/DC converter are connected to the bus. I am connecting this system to the bus using a connector i don't know the reference. See:

ok sorry let me be explain myself. Here is the schematic of my ECU prototype. I am using the CAN protocol to communicate with peripheral in the car.The PCU on schem represents the F446REWhen i connect this guy onto the CAN bus, after setting the CAN ...

Indeed, it seems that the problem comes from my old laptop, i changed and it works properly. Thanks!

Yes i have another board and i am facing the same problem no matter the board i am using.You said that you did the same thing on the same project and it works for you?
