Detailed Description
The MyTimers class creates a Ticker and decrements a collection of unsigned longs that act as timers across the program.
- See also:
- eTimerType is used to link external callers with a collection of unsigned longs which are decremented each ms by
- run(). This acts as a collection of timers. This collection can be set by
- SetTimer and retrieved by
- GetTimer.

Member Enumeration Documentation
| enum eTimerType |
- Enumerator:
tmr_GroveMeasure Used in GroveDht22 handler.
tmr_GprsPower Used to power the SIM900 on and off.
tmr_GprsRxTx Timeout waiting for a response from the SIM900 over the serial line.
tmr_SdWaitError Sd card has hit an error, wait before retrying.
tmr_MeasFlash Flash once every 2 seconds for heartbeat.

Member Function Documentation
| unsigned long GetTimer | ( | eTimerType | timertype ) |
GetTimer gets the value of a timer.
- Parameters:
-
timertype identifies the timer whose value we want to get
- Returns:
- the value of the timer

| void SetTimer | ( | eTimerType | timertype, |
| unsigned long | time_ms | ||
| ) |
SetTimer sets the value of the timer.
- Parameters:
-
timertype identifies the timer whose value we want to set time_ms is the value the timer will be set to, to start counting down from, in ms
