I’ve got a spark core and plan to use it for a project that requires to serial ports. Has anybody here used one of the I2C UART chips on the Core and gotten it to work? If so how about library to support it?
I’m thinking maybe using something like a MAX3107.
I thought maybe I could multiplex the single UART using a multiplexer chip such as a TI CD74HC4052E.
Anybody have thoughts and or experience trying to do this sort of thing using the Spark Core?
