configure sja1110 with external micro-controller S32K344EHT1VPBST by SPI

[SCoder41]

Hello,

I have an external micro-controller S32K344 and I want the micro-controller to sent the SJA1110A Configuration over SPI to start the switch.

So can you provide the needed switch configuration to work and the needed SPI register configurations for the the switch to receive this configurations and start the switch with it.

Or if you can provide a demo for sending the configuration from a micro-controller over SPI and receiving it by the switch to start it.

Thank you

Hi,

a configuration for SJA1110 can be generated by Python programming language based on SJA1110-EVM Configuration Tools. A configuration generated by this tool is then used by host controller which can configure the switch via SPI. It can be downloaded on this page:

Go to Design Resources -> Software -> SJA1110-EVM Configuration Tools
