Graupner HOTT telemetry control module.

Electric and General Air modules simulation supported. The module configured by default to use UART1 port and to simulate Electric Air module. The port number can be changed from modules section in airframe setup file.

Example for airframe file

Add to your firmware section: This example contains all possible configuration options, not all of them are mandatory!

Module functions

Init Functions

These initialization functions are called once on startup.

hott_init()

Event Functions

These event functions are called in each cycle of the module event loop.

hott_event()

Periodic Functions

These functions are called periodically at the specified frequency from the module periodic loop.

hott_periodic()
- Frequency in Hz: 5.
- Autorun: LOCK
  Periodic function automatically starts after init and can't be stopped.
