Hi,When i use HAL_CAN_Transmit to send a CAN message on STM32F4, if say I am in error passive or bus off condition, what error does the API return? If I am in error passive, what is the best way to reset the error count to 0?Where can i get the error...

Hi,On an Stm32f4 based board, we have the external crystal (8MHZ) mounted. The Firmware however uses HSI clock. Does the HSI drift have an impact on CAN communication with another device over a long period of time(say weeks)? Is it recommended to use...

I am facing an issue on one of our stm32f4 boards. We have a custom bootloader , which boots up the app as below __disable_irq(); HAL_RCC_DeInit(); __HAL_RCC_AHB1_FORCE_RESET(); __HAL_RCC_AHB1_RELEASE_RESET(); __HAL_RCC_AHB2_FORCE_RESET(); __HAL_...

Dear All,on my STM32F board, i have the uart rx pin not connected/floating. Due to too many noise interrupts, I have configured UART in tx mode only and disabled RX interrupts. Is this fine? Or should the internal pull up be enabled for the RX pin?

Thank you for your reply. I will check the points you have explained and revert.

Thanks for your reply, AutoBusOff is enabled. There are only two nodes on the bus and after some period of time (say days), one node is going into error passive (say when TEC exceeds 128). So when the other node requests some data, the second node is...

Hi @ASene.1, just curious to know if you were able to find any other method to reset the error counters?

Thanks for your reply. Sorry, the MSP assignment was incorrect when i pasted the code here.. I have updated the code This code works on rest of the devices and is seen failing only on 1 board so far. It is not dying in a while(1) loop in error or har...
