I can able to do "Loopback Mode" and I'm getting the desired output signal(CAN_TX). When I opted "Normal Mode" I can not see any output signal at TX pin.Here I have selected polling method only and not used any of the interrupt(eg:CAN1_RX0,TX Interru...

Recently I bought a CAN Transceiver(SN65HVD230 CAN Board Network Transceiver Evaluation Development Module) to convert CAN_RX, CAN_RX signals into CAN_H, CAN_L from a STM32L476RG Nucleo board. How can I check this Transceiver, whether it is working o...

I am using a USB-CAN Transceiver(Auvidea 70200), it consists a STM32F042C6C MCU. When I connect it with PC for the first time it was in "ST Device in DFU Mode". Using DfuSe Demo(v3.0.6) I tried to flash a .dfu file generated from a sample program of ...

When I built a sample code and tried to do the Debugging using STM32CubeIDE it was showing that "NO ST LINK detected! Please connect ST LINK and start the debug session.".This Transceiver contains 2 channels of CAN output and one side contains USB 2....

I had gone through the datasheet and user manual. I could not fined respective CAN_TX, CAN_RX pins on the board(Pin Number PA12(CAN_TX), PA11(CAN_RX)). These pins are not available on the Discovery board. Then how can I take CAN TX, RX data to the ex...

As you said I connected a resister across the CAN_H, CAN_L. Even though I am not getting the output.I was getting proper otput when I am using Loopback mode. Once I changed the mode to Normal Mode data reception is not happening. I came to know this ...

Thank you Uwe Bonnes for the reply. I understood that I loaded some wrong test application binary into the board. As you said I've checked both chip(STM32F042C6UX) docs and AN2606. I could not find any exposed pin for BOOT0 in order to forcefully mak...

Thank for the reply @Imen DAHMENNow HAL_CAN_Init() is working fine. When doing the debug it seems ok.Now HAL_CAN_Start() and HAL_CAN_ActivateNotification() are not working. HAL_CAN_Start() function is trapped inside the following "wait the acknowledg...

How to make use of "Normal Mode" available in bxCAN(STM32L476RG Nucleo Board)?

How to check the working condition of the CAN Transceiver?

USB-CAN Transceiver(STM32F0426U6) is not detected by the PC after a new .dfu file up-gradation

I want to make a USB to CAN Inteface for that I recently bought a USB-CAN Transceiver(Auvidea 70200 - contains STM32F042C6U). I tried to do some CAN testing using STM32CubeIDE Version: 1.4.0.

I have pruchased a STM32L476VG Discovery board recently. I wanted to build a USB to CAN Interface. For that purpose I need to take CAN Tx, Rx data lines from the STM32 Discovery board and I have to connect those lines to any external transceiver.

Re: I am unable to configure CAN in STM32L476VG Discovery board. I wanted to develop an application which sends CAN message and receives CAN message. I enabled 2 interrupts CAN1_TX_Interrupt, CAN1_RX0_Interrupt. I selected Normal Mode only .
