Driver for AMT22 encoder from CUI devices.

No detailed description...

Example for airframe file

Add to your firmware section:

<module name="encoder_amt22"/>

Module functions

Init Functions

These initialization functions are called once on startup.

• encoder_amt22_init()

Periodic Functions

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

• encoder_amt22_periodic()
  • Frequency in Hz: 50.0
  • Autorun: TRUE
    Periodic function automatically starts after init.
