How to add the vario to an Airwhere.
Step One.
i |
First purchase a GY-86 board, these shouldnt be too expensive, we have them on the shop site if your finding it difficult to find - also make sure you have a speaker attached - we need sounds for the vario ;) |
ii |
Add a small piece of black tape or neoprene to the top of the tiny pressure sensor on top of the gy86 but be careful not to cover the sensor holes, the pressure sensor is effected by light so we need to keep it in the dark so its stable. |
iii |
Follow the wiring diagram to setup the vario board. a breadboard can be used to temporarily check the system works ok, however soldering gives a better joint.
ESP32 | GY-86 board |
IO12 | INTA |
IO13 | SCL |
IO25 | SDA |
3V | 3V |
GND | GND |
|
iv |
To configure LK8000 or XCSoar to use data from this sensor, please change the device driver to be BlueFly Vario we will have our own driver soon but for now please use this, using this driver gives you barometric height and therefore a correct climb visual climbrate, also outside air temperature, this can be setup up in config |
Have fun with the project!
