I recently had two crashes with my copter, and was wondering if anybody can help me figure out what caused them. Before I begin, here's the specs of the copter:MTM size: 1400mmconfig: X8Motors: T…Continue

"I finally got it working! rather than the pins listed in Mission Planner, I used the following: BATT_VOLT_PIN: 3 BATT_CURR_PIN: 2 BATT2_VOLT_PIN: 14 BATT2_CURR_PIN:13 This pinout worked for the power1 and power2 ports, with the standard wiring of…"

"In that case, use Qgroundcontrol or APMPlanner2. It's an incredible achievement to cock that up if mission planner in fact messed it up. That would require some crazy logic to do so, as the data is sent over accordingly to mavlink…"

"Maybe it is a similar issue I found where in fact, after any change in mission planner in that current monitor window, you actually need to reboot the pixhawk board and reconnect mission planner to see the changes. Have you tried that ?"

"Thanks, I was sure to account for that. I was able to verify that the Attopilot was connected correctly. I verified with a multimeter. Unfortunately, the problem still persists."

"My bad. I did not mean _curr_pin Also check that current and voltage pins on power module connectors are swapped correctly, Pixhawk2 has pin 3 and 4 swapped on the power module clickmate connectors."

"Could you elaborate on this? The BATT_CURRENT_SENS is set to 3, as stated in the manual. Would an incorrect current sense pin also cause me to not read any voltages with the on the voltage sense pin(2)?"

Battery Monitor Works on Pixhawk 1 but not Pixhawk 2 Cube

I'm currently having issues with getting the battery monitor to work properly on my Pixhawk 2 Cube from ProfiCNC. I thought that perhaps I had the wrong pins selected, but the Pixhawk 2 manual states they are PA2 for voltage and PA3 for current. My test has been to take 3 battery monitors, and wire both a Pixhawk 1 and pixhawk 2 plug to it. I would plug into the pixhawk 1 first, to confirm it works correctly, and then into the pix2, where I couldn't get it to read voltage. I have tried this…See More
