@Lawrence King Thank you for the code! @All I tried the last few days to get it working but I don’t know how to use a second UART. I’m using the nRF52832dk board which has only “uart0” defined in the

I have used the Longan module with Zephyr on nrf52840. I connected it to a Serial, then modified the Longan library to compile and work under Zephyr. This isn’t everything you need (missing the .h inc

Hi all, I’m new to zephyr and need some help. I have a nrf52dk board and want to use this ( https://www.longan-labs.cc/1030001.html ) serial to CAN device. I was able to test this with an Arduino and

Hello everybody, this is my first post. I have a problem with the drivers/can/can_mcp2515.c interrupt configuration/the mcp2515 driver implementation. I would like to send a can message with the can_s

Josef, The BOARD_ROOT works for me even with Stm32 boards. The pinmux is mandatory for alternate functions on st boards. You can run the following commad to set the board root: west build -b hvac_sens

Update: CAN bus is working now with my board. I had to move by board config into the Zephyr tree, then pinmuxing seems to work. I still do not know the root cause. My configuration (for CAN) was ident

Hi, the driver is built into the kernel, but what I found out yesterday is, that the pinmuxing is not set up correctly. And the STM32 CAN controller will wait until it has received some bits before it

Hi Josef To me, the problem look more like you didn’t include the CAN bus drivers when you built the kernel. Try running ‘make menuconfig’ and turning on the CAN bus, then rebuilding. Lawrence King Pr

Hi Joseph, Which board are you using? Did you check that CAN driver is available for this board? Not sure it has been deployed for the whole STM32 family. Erwan

With some more debugging it looks like the STM32 CAN initialization fails in the STM32 HAL code: At HAL_CAN_Init() the loop waiting for the INAK bit in the CAN_MSR register to be reset when the initia

Hi, I am trying to get the STM32 CAN bus driver running with the latest revision from git. Unfortunately calling device_get_binding() fails and the reason for that is that the pointer 'driver_api' in
