TriWiiCopter: Connecting the brain
Today I disconnected the 4 HK401B Gyros from the three ESCs and 1 yaw control servo for the purpose of hooking up the new Arduino control board.
Tips:
1) Create a new model on my transmitter. I made the mistake of trying to re-use the existing model memory setup to fly my Tricopter where the Tx is programmed to do all the mixing and 120° CCPM. That job is taken over by the Arduino so a new model with just the basic config can be used.
2) Adjust (increase) the Throttle ATV such that the minimum throttle shown in the MultiWiiconf software is about 950. Once the Arduino sees a low enough throttle output, it will be able to arm the motors and set them at idle. If the Arduino reads anything above minimum throttle, the motors won't start as a safety feature.
3) Adjust the rudder / yaw control Dual Rate, ATV so that the output is in the 1000 to 2000 range in MultiWiiConf.
I'm still using the MultiWiiConf_prebis_1.6 only because I'd already configured it and had it up and running. Version 1.6 is the current version which I just need to configure and upload to the board. When the time comes, I'll try out the online configurator here http://ardupirates.net/config/MW_Config.php.
Now that everythings moving in the right direction in the software, it's time to put the props back on for a test flight. The old gyros will stay on till I'm sure everythings working ok.
