Module functions

Init Functions

These initialization functions are called once on startup.

humid_sht_init_i2c()

Event Functions

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

humid_sht_event_i2c()

Periodic Functions

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

humid_sht_periodic_i2c()
- Frequency in Hz: 4
- Delay: 0.
  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.
humid_sht_p_temp()
- Frequency in Hz: 4
- Delay: 0.4
  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.
humid_sht_p_humid()
- Frequency in Hz: 4
- Delay: 0.6
  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.
