Detailed Description

The reset and voltage in state machine responds to reset sources and pulls the reset line down for two seconds upon the reset source triggering. The detailed implementation is different for each reset source. The voltage in reset source pulls down for as long as it is running. It only reaches the two second countdown once the vin state is cleared. The WDT reset source fires once and automatically reaches the two second countdown.

Enumerator
eVIN_Init 

Voltage in and Reset State Machine Initial State

The state machine sets reset to true in this state, and the state machine transitions into this state when the Modbus WDT bites. eVIN_Init

eVIN_VLow 

Voltage Low State.

eVIN_OK 

Voltage in and Reset State Machine OK.

Definition at line 48 of file IoT_Supervisor.h.

Function Documentation

◆ VinSm()

void VinSm ( void  )

Voltage in state machine. Perhaps this could be called the main state machine in this application.

The state machine starts in the reset mode to enable a boot-up delay on the SBC so that screens and stuff can initialize before the board does.
