Automotive ECUs use cyclic communication and are event driven. ECUs send their signals over CAN at a defined message rate, regardless of whether the state has changed. Other ECUs set up their hardware to monitor the signals they care about, and trigger a hardware interrupt when the signal is received.

Would you use an NRF chip today, or is there another you would recommend? I'm working on a board with an NRF52840 and have been annoyed with their API. There are so many versions of their API and software, some are marked deprecated but the interface is still used in their latest code/examples. Nordic also doesn't provide a code generator to configure the hardware. I started with them since their chips seemed popular, they provided the BLE profile I needed, and come with a Segger debug license.
