Hi, I am using 8 bit simple BGC 2 axis gimbal controller. I want to rotate the Pitch of gimbal based on external PWM input given to RXPitch pin of it. I have seen couple of videos about how to interface RC to gimbal controller. I provided a constant PWM signal of 50Hz, 1.5msec pulse width signal on RX_Pitch pin but i dont see pitch motor moving at all. I also tried changing the pulse width to 1.7msec and motor dint rotate at all. Could anyone tell if i am missing any step? Or how can i change pitch angle from external PWM input? Software configuration: In RC setting PWM is selected with ROll and PITCH, Minimum and maximum angle is set to -45 to 45 deg repectively and angle mode of operation is selected. The PWM signal is generated from external controller and its 3.3v pulse. Motor supply was connected.
what port did you plug the RC receiver in to ? you need to know what port, then configure the port in RC tab, then verify the port is working in display tab!
@AOPEN3434 Its not RC receiver but a arduino kind of microcontroller which generates PWM signal of 50Hz. I could see pulse width 1516(corresponds to 1.5ms of pulse width) being displayed on display port but motor does not move. Which port should i select in this case and how to find it out? Thank you.
@AOPEN3434 Thank you. Roll axes seems to be working but pitch doesnot. I observed that if i hold my gimbal straight in air, the pitch angle shows 180 degrees. Is it correct?
