I just signed up for the Ardupilot discourse - it’s been a long time coming. I’m having a similar issue, so I thought I would touch base.
I’ve been trying to connect the PX4FLOW and A TFMINI Pro to the i2c A port. I recently updated he firmware from Pixhawk to Arducopter - at one point I had the PX4 flow ‘sort of working’ on the i2cA (it seemed unreliable, worked part of the time.)
After updating the firmware, I cannot get data to work through i2c A on either device - tried one at a time, also I tried separately powering the i2c splitter using clean 5v - no luck.
My current situation: Partial solution - connect the TFMiniPro Lidar to the UART/I2C port as a serial device. Data/readings work.
Still in the weeds on the PX4FLOW.
Have you made any progress on this front?
Ardupilot 4.0.3 installed on Pixhawk fmuv5
PX4Flow-KLT firmware installed on the PX4flow
Mission planner does not show dropdowns for Rangefinder or Optical Flow checkbox; even when the lidar rangefinder is connected and working.
Mission planner ‘focus’ button does nothing when connected to the px4flow via usb (I also tried setting usb stream video to 1.)
Q-Ground Control does allow me to connect to the px4flow and focus the camera, so I know it’s not that…
