Hello,
I recently purchased a Power Module v3 for a VOXL CAM. When I run "voxl-inspect-battery" I get N/A. This is also received on the web GUI and QGroundControl. I need to have this function working to fly the drone.
To debug I've done the following steps:
-
Used the command "voxl-i2c scan 8 400000" to see if the VOXL CAM can read any I2C devices on the power port. None showed up. I tested the command on the port with the barometric pressure sensor and the scanner is working properly as it found the device.
-
I then used a hardware I2C scanner I have and plugged it into the Power Module v3, and it was able to discover the devices at 0x44 and 0x45. The power module appears to be functioning correctly.
-
I wired a oscilloscope to the output of the VOXL CAM to scan the I2C port and verify the wiring and that the VOXL CAM is sending read commands. I was able to see the commands being sent and that the system is wired correctly.
What can I do to properly setup this module? Is there anything I might be missing?
Thank you,
Justin
