• name: AOA_FILTER value: 0.5
  Description: filtering parameter between 0 (no filtering) and 1

Module functions

Init Functions

These initialization functions are called once on startup.

• aoa_adc_init()

Periodic Functions

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

• aoa_adc_update()
  • Frequency in Hz: 60.
  • Autorun: LOCK
    Periodic function automatically starts after init and can't be stopped.
