Hello,
We are looking to drive an actuator using the PWM out signal from the Autopilot. In this direction, we wanted to build an App for doing this & we are very new to development in PX4. Using the tutorials we are able to setup a toolchain for compilation & we were able to successfully try the examples provided towards this setup. We are using a Pixawk 2.4.8 in order to test the codes. Using these examples, in order to start the PWM, the following function will need to be used :
px4_ioctl(fd, PWM_SERVO_SET_MODE, PWM_SERVO_ENTER_TEST_MODE);
With the fd = px4_open(dev,0); & the const char *dev = PWM_OUTPUT_DEVICE_PATH;
However, we are getting an error that the “PWM_OUTPUT_DEVICE_PATH” is not declared & we wanted to know how can the path be provided.
With Regards,
ARK
