[tlug] MCU functionality in linux/books?

["Miles Colman" <mcolman@example.com>]

Hello everybody,

I'm trying to get micro-controller style functionality out of linux
and looking for resources/book recommendations.
Specifically, I want to read in data on a serial port (using an
interrupt or a buffer that gets read at 100 Hz with low latency),
process the data and send it out soon after processing (again, with an
interrupt or fast polling).

I have Linux Device Drivers, 3rd ed.  and The Captain's Universe:

Does anyone else have some favorite references they'd like to share?

Thanks,
Miles
