Communication Protocol Description
The control signal adopted by the PPM Motor Driver Board is the PPM output signal of the Airmodel Remote Control Standard, which can be directly connected to the Airmodel Remote Control Receiver. The signal is a PWM signal with a frequency of 50Hz, sliding remote controller rocker, the high level duration of the signal is controlled by 1000us ~ 2000us.
Control Signal and Drive Signal
Control Signal
PPM Motor Driver Module supports 2-way independent DC motor drive, driving signal from CH1 and CH2 input, respectively corresponding to M1 and M2 motor drive output. CH1, CH2 can be directly connected to the receiver of aeromodelling remote control (such as FS-IA6B transmitter). It can be also controlled by Arduino Servo code.
PPM Motor Driver Module has 5V power output, it doesn't need to connect power, when you connect to the receiver.
The control signal adopted by the PPM Motor Driver Board is the PPM output signal of the Airmodel Remote Control Standard, which can be directly connected to the Airmodel Remote Control Receiver. The signal is a PWM signal with a frequency of ''' 50Hz ''', sliding remote controller rocker, the high level duration of the signal is controlled by 1000us ~ 2000us.
-
When the high level duration of the control signal increases from 1000us to 1469us, the motor turns forward and the speed decreases gradually.
-
When the high level duration of the control signal increases from 1561us to 2000us, the motor reverses and the speed increases gradually.
-
When the high level duration of the control signal is between 1470us and 1560us (i.e. the joystick returns to the center-point), the motor stops rotating and the motor drive port outputs a low level. (An intermediate stop field has been added due to possible mechanical errors in the remote control.)
PPM Motor Driver Module doesn't have brake function.
Drive Signal
Drive signal refers to the signal used to drive the motor to rotate after the control singal received by the PPM Motor Drvier board is proccessed by the STM8S105 chip. They are two PWM signals with frequency 1000Hz for controlling motor speed and direction respectively.
