Good morning all,
There is an ad running in Digital Machinist magazine for an RC speed control of
a brushless motor with ESC. If interested go to www.logicnc.com
It gives EMC2 a way to control spindle speed from the parallel port. I haven't
used one yet though.
Cheers!

Seems like a waste to only use up to 2ms of the 20 ms time slot...
Not really: this 'protocol' was originally
This is a legacy of the RC data format. The signal is transmitted as a

Hello Dave,
the RC protocol is very prinitive and thus very flexible. In order to
make more channels possible I use a variable time slot which adds up by
ten variable pulses (correctly, pulse pauses from 1 to 2 ms) which
contain the channel informations plus a 10 ms sync pulse (can be reduced
OK, now I understand.. Makes sense since RC model planes have been
around for a long time.
Thanks, Dave

By the way, virtually all brushless ESCs will accept a frame rate of up
to 400Hz (2.5ms interval). I do that in my quadcopter controller to
increase the bandwidth. Quadcopters need very fast ESC response for
stability.

Has anyone tried to use and RC controller with EMC to run a RC brushless
motor
Hi!
I try to use it.
Work still in progress, but control part is almost done.
