STM32CubeMX - V6.12.0 CAN-FD Transciever Delay Compensation & Auto Retransmission

[CZuercher_Ilm]

Hi,

I'm currently using STM32CubeMX V6.12.0 to initialise the peripherals on an STM32H753 processor, and I had a couple of questions:

1. How do I enable & then configure the CAN Transciever Delay Compensation within CubeMX?

2. Is there a mechanism for limiting the number of auto-retransmissions in the event of a CAN Error? I currently have that option unchecked but when doing bench-top testing it's clogging up the processor and causing it to run slowly.

Many Thanks,

Crispin

Hello @CZuercher_Ilm 

First let me thank you for posting.

About the CAN Transciever Delay Compensation, it is not possible to configure it from within STM32CubeMX.

For more details, I will redirect your question to the STM32MCUs forum as it is a better place to get help with the CAN configuration.

KR,
Semer.

You can disable completely the retransmission with Init.AutoRetransmission = DISABLE.
