Re: [Emc-users] Has anyone tried to use and RC controller with EMC to run a RC brushless

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. Les On 08/11/2011 16:09, Jon Elson wrote: > This is the RADIO format, where

OK, now I understand.. Makes sense since RC model planes have been around for a long time. Thanks, Dave On 11/8/2011 10:19 AM, Peter Blodow wrote: > 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 whic

Re: [Emc-users] Has anyone tried to use and RC controller with EMC to run a RC brushless

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 t

Re: [Emc-users] Has anyone tried to use and RC controller with EMC to run a RC brushless

This is a legacy of the RC data format. The signal is transmitted as a series of short fixed width pulses, one pulse per channel. The time between each pulse gives the output pulse width for that channel. This repeats for the rest of the channels. 20ms gives enough time for 8 channels plus a sy

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! - Original Message -
