Hi,
I need to be able to send some simple data from one teensy 3.2 to another. This will be used to trigger actions, so it's not a stream of data, or very complex data. It could just be simple numbers, but strings would be handy. They would just be sent as a result of other actions, so i don't think speed is particularly important. Latency between sending and recieving - yes, but not a high speed transfer of multiple pieces of data.
I started looking at SPI, but I see that doing master/slave configurations is quite complicated on teensys... I read through this https://forum.pjrc.com/threads/50008-Project-SPI_MSTransfer but I think it's overkill for what I need.
Should I just be using a simple serial transfer, or wire?
Or I2C?
It seems there are probably many many ways to do what I want, but I'm confused as to which is the most fit for my purpose.
Thanks for any advice!
