Major update this time guys and gals.

Version now set at 0.20.00.

Frequency Counter added for the symmetrical waveforms sine, square, triangle, (and maybe sawtooth).
This is for the future addition of the DC component and measures from 50Hz to 3500Hz to within 0.1% accuracy.
In DEMO mode this will always read 500Hz as that is the file manually generated for the task.
Many thanks to "agama" some time ago for his input using an array to speed up the Freq Counter time.
Worked an absolute treat...

Code now added for the creation of running files ready for the vertical calibration.

Note, that the vertical amplifier and calbrator are built and the circuit for the calibrator is adeed to the
end of the script.

The Windows version of the vertical calibrator SW works as a genuine file under Windows but as this is generated
on the fly it has NOT been transfered and tested yet. Feedback would be most welcome on this one. It should give
a 1KHz tone for around 8 seconds ONLY and has to be rerun ATM...

Enjoy this latest update...

Bazza...

SET_TIME_LIMIT(3)							 1							 SET_TIME_LIMIT(3)

set_time_limit - Limits the maximum execution time

SYNOPSIS
bool set_time_limit (int $seconds) DESCRIPTION
Set the number of seconds a script is allowed to run. If this is reached, the script returns a fatal error. The default limit is 30 sec- onds or, if it exists, the max_execution_time value defined in the php.ini. When called, set_time_limit(3) restarts the timeout counter from zero. In other words, if the timeout is the default 30 seconds, and 25 seconds into script execution a call such as set_time_limit(20) is made, the script will run for a total of 45 seconds before timing out. PARAMETERS
o $seconds - The maximum execution time, in seconds. If set to zero, no time limit is imposed. RETURN VALUES
Returns TRUE on success, or FALSE on failure. NOTES
Warning This function has no effect when PHP is running in safe mode. There is no workaround other than turning off safe mode or changing the time limit in the php.ini. Note The set_time_limit(3) function and the configuration directive max_execution_time only affect the execution time of the script itself. Any time spent on activity that happens outside the execution of the script such as system calls using system(3), stream operations, database queries, etc. is not included when determining the maximum time that the script has been running. This is not true on Windows where the measured time is real. SEE ALSO
