This app is the head unit for a pump controller that fills the ballast bags in a wakeboard boat. It also has GPS speed, direction and distance. Gyroscope pitch and yaw. These tools can help you drive well for wakeboarding. Driving in a straight line and keeping the boat level is key to having a good wake.
What's new (v2.0)
Added a switch to empty out the bags. This sends a BLE message to the controller to reset the timers that track how long the bags have been filling. You would use this if you have fully emptied the bags, but the controller still reads them as partially full.
