Use board as HoTT telemetry sensor
Introduction
HoTT telemetry was introduced by Graupner into his RC radio and allow connecting various sensors to the receiver.
A Revolution, Revonano or Sparky board can emulate this modules and send telemetry data to the radio.
The following modules can be enabled:
- Vario
- GPS
- EAM (Electric Air Module)
- GAM (General Air Module)
- ESC
Wiring
HoTT receiver can be connected to the Mainport or FlexiPort and FlexiIO (receiver port) on Revolution board.
With a reduced size a Mini Revolution board can be used as well, taking in account the receiver port has 8 pins instead of 10 pins in original Revolution board.
Hardware setup
Revolution board can provide HoTT telemetry on FlexiIO port (receiver port), for other boards you need to use the MainPort or FlexiPort and configure the port with HoTT Telemetry.
Two options are available for telemetry output on FlexiIO (receiver) port: HoTT Telemetry or PPM +Hott Telemetry
HoTT configuration
UAVOBrowser
All configuration settings can be found using the UAVOBrowser in System tab.
- Sensors: Enable or Disable the sensor to be emulated
- Limit: Set the limit values used as alarm
- Warning: Enable or Disable alarm
Save settings using the save icon
