Controlling servo/gripper from VOXL2
-
Hello community,
I am using VOXL2 with latest SDK 1.1.2. On my custom UAV I have requirement to control a servo for gripper application. As far as I can see documents SDK 1.1.2 with VOXL2IO supports PWM but only upto 4. Is it correct ? Since mine is Quadcopter and all my PWM's would be anyways occupied with this. If yes then is there any other way by which I can have PWM output's controlled by VOXL from application side or PX4 DSP side? (I am aware of PCA9685 as I2C to PWM convertor chip which can be used over here but wanted to check if there is any direct method apart from this.)If PX4 DSP firmware can by any means control servo via VOXL2IO apart from 4 channels of main UAV motor controls that would save my efforts on processor side to integrate this board.
