Output Waveform Of Reciever And The Bldc Controller

[CLEMENT]

I AM NOW TRYING TO WRITE THE PROGRAM OF BLDC CONTROLLER USING 8051?
CAN ANYONE SHOW ME THE OUTPUT WAVEFORM OF THE MINI RADIO RECIEVER AND THE BLDC CONTROLLER? :confused:

Here are some of my homebrew controller, the first two are of the motor outputs at different locations, the last one a pic of the radio waveform.

The radio waveform is a PWM-based system, with a high output pulse of 1-2ms, with a 10-20ms dead time between pulses...a slow system.

I was using a PIC 16F819 for the project, but the concepts are the same for any MCU. I stopped development out of frustration getting the motor to start reliably...it is harder than it sounds.

Best of luck to you on this project, if you need more details on any of the shots feel free to ask!

CLEMENT .. go find AN857 microchip application note and read it. It will answer most of your questions.

Rx output is per Zagirule answered that one
