background waiting for a message on the bus, then you get your web
application to send a message to the program telling it turn on/off an
LED. The C program runs as root and as such has control of the hardware
and your webapge never calls the C program, but only sends data on the
message bus, so
onstraint.
You could investigate using the PRU's on the beaglebone's which can be
programmed and executed in a real time deterministic manner. You could
also use a bare-metal implementation to gain real-time functionality, or
try Xenomai.
So the answer is Yes, and No. More research on
