Single button function

You're doing something wrong...

When setting the Time, you can see all the fields (by field, you can see Hours, Minutes and Seconds on the same line, and as you press momentarilly, only the field you are currently parked on will change. When you hold for SET, the cursor changes from an underscore to a Block and on finger release moves to the next field, leaving the previous one with the content you set.

I refer you to the Button-02 picture... there you can see the underscore cursor parked in the Hours field... pressing momentarily will advance Hours through to 23 then cycle around starting from zero. Hold the Button for SET and the cursor changes to a BLOCK, and on finger release moves to Minutes changing back to an Underscore.

Check your $FE,xx's are the same as mine...

Duh! <smacks forehead> my switch routine had a LCD clear command in it.

Good day

I'm a picbasic newbie i'd like to ask these syntaxes do?

AMPMFlag=AMPMFlag^1 '>>>>>>>>>>>>>>>>>>>what does this do?

Lc var byte [15]
For i = 0 to 15 : read i, b0:if b0 = 0 then
lookup i,[1,2,3,11,4,5,6,11,7,8,9,10,11,12,13,14], b0
Lc(i)=b0 '>>>>>>>>>>>>>>>>>>>>>>>>>>>what does this do?
goto Address

I would gladly appreciate for any response
thanks

AMPMFlag=AMPMFlag^1 '>>>>>>>>>>>>>>>>>>>what does this do?

AMPMFlag is a BIT variable.
All this does is toggle the BIT variable, if it was zero it will be set to 1, if it was 1 it will be set to 0. It is the equivallent of...

IF AMPMFlag=0 then
AMPMFlag=1
else
AMPMFlag=0
endif



Lc var byte [15]
For i = 0 to 15 : read i, b0:if b0 = 0 then
lookup i,[1,2,3,11,4,5,6,11,7,8,9,10,11,12,13,14], b0
Lc(i)=b0 '>>>>>>>>>>>>>>>>>>>>>>>>>>>what does this do?

Lc is a BYTE array 15 elements deep in the range Lc(0) to Lc(14)
You are loading Lc at array location i with the contents of variable b0

Thank you Mel,
I am incorporating your olympic timer in my medicine scheduler project I used some code snippets from les Johnson's book "experimenting with picbasic" I also read your thread with bits,byte, and arrray handling and found it intuitive!!!
I am still fixing my keypad routine to scan and output to LCD like a mobile fone does(",) I am trying to find a lcd menu routine for my display I will post it later on a new thread

thanks again

here is a chip that will give you 2 button's on one i/o

You seriously want to pay $1 for a 2 I/O expander?

If you need two buttons on one I/O, then you can achieve that with a different value of Capacitor on each of two Buttons and measure the time period for charge. Cost about 5 cents and a bit of magic in software...
