Hello, I finally finished my boat, and now need to implement the hardware. I am running into a lot of frustrations right now however.
In addition to many non-generic connectors with every instrument I buy, I am having trouble figuring out how to connect the pixhawk to my arduino. I noticed the pixhawk has DF13 connectors, with converters to JST for the power cable. The pixhawk also came with a cable that has one end JST and the other end female pins for the ICSP connections on the arduino.
My question is: What hardware/software/cables do I need to connect the arduino to the pixhawk by either I2C or Telem2 as some forums have suggested? Any preferences, pros/cons? Do I just connect the serial RX, TX and G pins, or all 6 I2C MISO, SCK, Reset, VCC, MOSI, GND?
Goal: I want to control a boat with gps and sonar with the pixhawk. I then want to record that data to an arduino mega with sd card logger so I can plot it up on a computer when I get home. I am very stuck on the hardware part now between the pixhawk and the arduino.
Thank you in advance!
