Freematics ONE+ maximum bandwidth
Posted: Mon Jun 14, 2021 9:10 pm
I am going to use the Freematics ONE+ for a project where I need to monitor a 500kbps/11bit CAN BUS that has a high utilization (around 40%).
Is that possible with the current HW/SW?
As far as I can tell from the source, the interface between the STM32 and the ESP32 is a 1Mbps SPI with standard ELM327 communication - thus 3 bytes used on SPI per 1 byte of CAN data.
Is that correct?

Søren
