LIN-bus SW driver for nRF5x

[tompa21]

I would like to add LIN-bus to a project of mine. The hardware part is easy, connect a LIN interface ASIC to the UART of the nRF5x. But writing my own LIN-bus SW driver that fulfills the LIN-bus standard is something I would like to avoid.

Does anybody know if there is a LIN-bus SW driver available that will work with the nRF5x series and/or that can be adapted to it with minimal work.

Thanks, Thomas

I am working on a LIN slave. Have you found anything for this yet?

I have working code on an Atmel 2560, just porting it to the NRF52 now. The complication I am foreseeing is that on the Atmel part I could disable Rx and Tx at will. It seem on the NRF that I have to disable the whole UART and then maybe drop the Rx or Tx pin.

LIN bus requires to hold the Tx bus high while receiving. When transmitting, the Rx is seeing what is Tx'd - so I shut off Rx when I transmit.

Any help/thoughts?

Thanks! Tom
