Module functions

Init Functions

These initialization functions are called once on startup.

Event Functions

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

Periodic Functions

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

  • srf08_initiate_ranging()
    • Frequency in Hz: 1
    • Autorun: LOCK
      Periodic function automatically starts after init and can't be stopped.
  • srf08_receive()
    • Frequency in Hz: 1
    • Delay: 4
      Integer to impose a sequence (between 0 and main_freq/function_freq)
    • Autorun: LOCK
      Periodic function automatically starts after init and can't be stopped.
