Version	14.0
Category	Timing

Timer component

Allows you to measure the passage of time via the use of a hardware timer peripheral. Works like a stopwatch with macros to start, stop and reset the timer counter. Returns time as integer Seconds, Milliseconds, Microseconds and also Floating Point and String.

Examples

Here is a basic example showing the operation of the timer component used to time a section of code or the duration of a specific event.

Timer Example

Macro reference

GetCountMicroSeconds

	GetCountMicroSeconds
Returns the count value as a number of whole microseconds, rounded down to the nearest microsecond
- ULONG	Return

GetCountMilliseconds

	GetCountMilliseconds
Returns the count value as a number of whole milliseconds, rounded down to the nearest millisecond
- ULONG	Return

GetCountReal

	GetCountReal
Returns the count value as a floating point value in seconds.
- FLOAT	Return

GetCountSeconds

	GetCountSeconds
Returns the count value as a number of whole seconds, rounded down to the nearest second
- ULONG	Return

GetCountString

	GetCountString
Returns the count value as a floating point string in seconds.
- BYTE	Precision
Number of decimal places to display in string
- STRING	Return

GetRawCount

	GetRawCount
Efficient command to collect the integer number of instructions since the timer was started.
- ULONG	Return

ResetCounter

	ResetCounter
- VOID	Return

StartCounter

	StartCounter
Starts the timer counting.
- BOOL	ResetCounters
Range: 0-1 where 0=Do Not Reset and 1=Reset
- VOID	Return

StopCounter

	StopCounter
Stops the timer counting.
- VOID	Return

Property reference

	Properties
	Timer
Timer Peripheral to use to monitor the passage of time.
	Prescaler
	Postscaler
	Bit Depth
Number of bits in the timer peripheral. 8-bit timers can count from 0-255 before overflowing. 16-bit timers can count from 0 to 65535 before overflowing.
	Instruction Rate
	Rollover Frequency
	Rollover Time
	Max Time Measurement
Max time in seconds that we can measure before rolling over and starting again.
	Simulation
	Timer Delay (ms)
Number of milliseconds between timer events which increment the simulated timer counter variable. 10ms will yield the highest resolution. Values less than this will likely just increase the error and making the timer run slow. Higher delays will yield greater accuracy.
	Decimal Points
