Hello everybody,I try to get canbus communication on the blue pill+ under zephyr to work. I use the canopennode sample. I got the following overlay: / { model = "STM32 Minimum Development Board (Blue)"; compatible = "stm32_min_dev_blu...
Hello!! I'm trying to use both CAN peripherals in an STM32F446RET6R on a custom PCB, but something is not going well enough. I've done the basic configuration using the STMCubeIDE platform (I'll add the code later, but first I want to know if someone...
Hello,customer using custom F412 based board has a problem entering STM's System bootloader/DFU for FW upgrade (done over USB) when there is an active communication done on the CAN port.E.g. the board is part of the slave HW of the CANopen network wh...
Hi All,I am currently working on the CAN normal mode in a custom board with MCU STM32F098RCT6 and CAN transceiver TJA1042. Very first I tried the loopback mode and it was successful. Then I am now trying to interface two custom boards using the norma...
I am working on NUCLEO F446RE, I need to use CAN1 and CAN2 on the STM32 NUCLEO-F446RE board. I tested CAN1, which works normally for sending and receiving data, but when I tried CAN2, it didn’t work at all. I looked for solutions in https://community...
You can see my codeThe 'send_frame' / 'CAN_CMD_STD' functions are about CAN bus transmission.Removing 'CAN_CMD_STD' code will make all my code work. In particular, the 'data_set1' array can contain appropriate adc values.But if I add 'CAN_CMD_STD' co...
Dear, I am trying to run the CAN Communication in STM32F407 discovery board, In CAN_INIT I have made controller state to Ready after that I have changed the controller state from ready to LISTENING in CAN_START function, but when I am trying to exe...
Hello, In my STM32F407 discovery board, I want to run can communication for which firstly I set the INRQ bit CAN_MCR register then my INAK bit in CAN_MSR register is also got set by the hardware. Then for starting the can I want to clear the initiali...
Hi, I am new to ST, trying CAN TX RX Code. Every time I Transmit Error frame is getting generated instead of Data . Please suggest what i am doing wrong in the below code. I am sharing my main file Thanks
