Olympic Timer MPH readout

[Macgman2000]

Hello Melanie,

I guess the question would be, where in your Olympic timer code can I add the math to calculate the speed d/t=s. Since it will be over a 10 foot distance I would want to use the hundredths of seconds variable you have in the code. I am expecting no slower than 5mph and no faster than 30mph.

Best Regards,
Nick

This is the current Display Code...

DisplayLoop:
	If ButStart=0 then RunningFlag=1
	If ButStop=0 then RunningFlag=0
	LCDOut $FE,$80,DEC2 Hours,":",DEC2 Minutes,":",DEC2 Seconds,".",DEC2 Hundredths
	If OverflowError=1 then
		If Seconds.0=1 then
			LCDOut $FE,$8C,"ERR"
			else
			LCDOut $FE,$8C,"   "
			endif
		endif
	If RunningFlag=1 then goto DisplayLoop
	If ButReset=1 then goto DisplayLoop
	Disable

You could completely rehash it, or simply tack-on the math and display like so (assuming a 2-lince LCD screen)...

DisplayLoop:
	If ButStart=0 then RunningFlag=1
	If ButStop=0 then RunningFlag=0
	LCDOut $FE,$80,DEC2 Hours,":",DEC2 Minutes,":",DEC2 Seconds,".",DEC2 Hundredths
	If OverflowError=1 then
		If Seconds.0=1 then
			LCDOut $FE,$8C,"ERR"
			else
			LCDOut $FE,$8C,"   "
			endif
		endif
	If RunningFlag=1 then goto DisplayLoop

	' *** perform math here - assume resultant variable mph is in tenths of mile/hour

	LCDOut $FE,$C0,#mph DIG 2,#mph DIG 1,".",#mph DIG 0," mph  "
	If ButReset=1 then goto DisplayLoop
	Disable

that way you get the elapsed Time ticking, with the mph only being displayed (to one decimal place per my above example) after the clock has stopped.
