Detailed Description

File Map:
FH_Root, Section FH_General, FH_GlobalTimerCount
There are a diverse range of different situations where a precise timing is a necessity
To have a general heart beat (1 mili-second) for all different parts of the code, a timer in the micro-controller on which FH source code is ported, shall be utilized
FH_GlobalTimeCounter here shall be incremented every 1 mili-second in an interested timer ISR (Interrupt Service Routine) by FH user
For this to happen, FH_GlobalTimerCount.h shall be included in the interested timer ISR (Interrupt Service Routine) file

Warning

If FH user would not increment the FH_GlobalTimeCounter in a timer ISR (Interrupt Service Routine) every 1 mili-second, the related commands (which require timing) will have malfunction

Attention

FH user could left this file intact but shall include FH_GlobalTimerCount.h in the interested timer ISR (Interrupt Service Routine) file

Function Documentation

FH_Reset_GlobalTimeCounter()

void FH_Reset_GlobalTimeCounter

(

)

This function resets the FH_GlobalTimeCounter if need be
FH_GlobalTimeCounter here shall be incremented every 1 mili-second in an interested timer ISR (Interrupt Service Routine) by FH user
For this to happen, FH_GlobalTimerCount.h shall be included in the interested timer ISR (Interrupt Service Routine) file.

Parameters

None

Returns

None

Note

Since the mere heart beat of the FH code is FH_GlobalTimeCounter and it is getting incremented every 1 mili-second, it is normally required to reset it to start a new time calculation
