Olympic Timer MPH readout

[Macgman2000]

Hello,

I want to display miles per hour rather than seconds or milliseconds using Melanie's Olympic timer. Has anyone modified the code to do that? I would appreciate any help!

Best Regards,

Kinda vague question...

If the Start and Stop Buttons are sensors between a known set distance, then all you need is the addition of a bit of math to give you mph.

If however you're counting pulses from a tacho or other sensor, then that code is probably not suitable.

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.

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.

Hello Melanie,

Thank you for their answer, I have this code and I want that when it is I number 1 blink, I number 2 blink and I number 3 blink but I cannot make it you can give me some suggestion.

Thank you

Your question isn't exactly anything to do with the topic being discussed here Leonardo. Please post in the appropriate section adding which compiler you are using PBP or PBC and what PIC you are programming for.

Thank you, but then which is the section to ask the question, my compiler is PBP and the pic it is PIC16F628.
