In addition to eight high current

channel status), eight TTL inputs, and a
full-duplex RS-485 port, it has an option
for adding a microSD socket which
means we can create a unified program
to play live Vixen data, or from a show
file on the microSD card.
The output drive to the high current
transistors is fed through servo-compatible three-pin headers so the
board can — with a bit of software — run
servos and high current dimmers at the
same time. This is why it’s my favorite for
small prop and animatronics control. Have a look at the
program, jm_hc- 8+_vixen_player.spin. It uses all of the
code we’ve discussed here in a unified program, and even
includes a few extra goodies that we didn’t have time to
