Single button function

[Archilochus]

Your example had the same issue. User sees no change in the display until the button is released.

I will look into placing the while:wend after display update.

Other than my goof with the WHILE / WEND, the code will jump to a new menu after a HOLD of ~ 1 second. If only pressed, the button test loop ends immediately, and the code continues as needed after a press & release.

The button test loop auto-terminates after 2 seconds, so even if the user continues holding the button, the code will jump to the new menu anyway, and only after writing the new menu, does it then wait for a button release.

Melanie I've added your code into my project. When setting the times hours, minutes, or seconds the display clears and only displays the value that is currently being altered. Are you seeing the same thing or am I missing something?

[Melanie]

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
