i plugged my temperature sensor and my depth sensor on a I2C splitter and that goes to my 1 I2C port on my pixhawk. I opened up QGC and it appears that i am getting my depth reading but i cant find the temperature reading. where can i go to get that number
Click the gears icon next to the compass, and you can choose temperature sensor to display.
should i pick Tempreture 1 or Temp 2 or Temp 3
btw what should i click to get the readings from the depth sensor
You should be using QGC provided from the ardusub website: https://www.ardusub.com/resources/downloads.html
The temperatures and depth values will be labelled.
