Module configuration options

Configure Options

• name: ADC_AOA value: ADC_X
  Description: select the ADC channel to use

Define Options

• name: AOA_SENS value: (2*3.14)/1024
  Description: sensor sensitivity
• name: AOA_OFFSET value: 3.14
  Description: offset in radians
• 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.
