I'm reading RM0351 for STM32L476, "To be synchronized the hardware has to monitor a sequence of 11 consecutive recessive bits on the CAN RX signal." Is RX recessive bit a digital high or low signal? I couldn't find the info on the datasheet which onl...

Hi all, I'm using STM32L476 and I am using its BxCAN with a transceiver TJA1042. I have the transceiver's RXD to STM32's CAN_RD1, and TXD to CAN_TX1. Both pins on STM32 are set to be pulled up. And the transceiver does have a 3.3V reference. There's ...

I'm thinking of using PB8 CAN1_RD and PB9 CAN1_TD on STM32L476 . And I don't think we can map them to other pins, is that right?

Hi all,Our team is developing on a custom PCB with STM32L476. And we are testing our CLI robustness, we found out that when we spam the CLI which uses USART2 at baud rate 115200, the program goes into hard fault. Upon investigating with a JLINK debug...

did you ever solve this problem? It's mentioned countless times on the internet and this forum. I'm using STM32L476, and I think it's happening on it too. I tried out the solution for F1 on L476RG written in this post https://electronics.stackexchang...

So what I found is before the bus fault and hard fault, the memory map of huart->Instance showsand after the fault, it shows:which according to visualGDB I am running in visual studio, the memory region is not readable.

What's the bXCAN RXD recessive signal on STM32L476?

HAL CAN module using BxCAN fails to initialize when RXD and TXD aren't physically connected.

can CAN pins be swapped to other IO pins?
