Need some (export) advice, a Simple LIN Master?

[onesixright]

Hi,

I have a LIN Master remote, i decoded the signals, now i want to recreate  this my with own MCU and these signals (in essence replicating the remote).

My question is what would be the simplest way to create a LIN master? I have a Arduino, RPI, and some Microchips laying around. Obviously the smaller the better (RPI is pretty much overkill).

Thanks.

It appears you can use any uC that has a UART and even that isn't cast in stone.  So it gets down to how many messages you need to send/store/create.  Does the uC have enough memory to hold them.  19.2 kbps isn't going to challenge any modern uC.

The easiest platform to start with is the Arduino.  I would probably start with that device even if I planned to move down to a PIC sometime in the future.  Once the software was well understood, it's easy enough to port it to a different device.

Still, it might come down to pins.  Does the Arduino have enough pins for the human interface.  If not, you will need to choose something that does.

Write down all the requirements as column headers in a spreadsheet and then enter uC capabilities on the rows.  Something will make the cut!
