Detailed Description

Auxiliary hardware driver for ESP-AJAX-Lab This implements GPIO control for relays, fan, enable and reset signals and PWM generation used as a reference signal for hardware overcurrent limiter.

Further, temperature sensor readout is triggered here by calling update_temperature_sensors() member peroiodically from timer task in PsPWMAppHwControl::on_periodic_update_timer().

This class is also used as a container for its public attribute members which represent the hardware state and are read-accessed externally.
