symbol led_2 = portb.1
symbol led_3 = portb.2
button var porta.0
b0 var byte
portb = 0
porta.0 = 1
main:
count button,1000, b0
if button = 0 then
high led_1
pause 100
low led_1
if button = > 0 then
high led_2
pause 100
low led_2
if button = ??? then
high led_3
pause 100
low led_3
goto main

Have you tried to read B0 variable instead?

Does it need to have a timeout? If so, probably not a bad idea to process COUNT only when you press on your push button.

hi mister_e im new in pbp i will try many ways and i hope someone here has a good ideas how it works ,thnks mister_e.

You should use temporary counter like this:

start:
button blabalabla... click
if a= 1 then blablabla
etc..
goto start:

click:
a=a+1
goto start

Don't you need some ENDIF statements through the code ?

You should initialize B0 to be 0 and it's best to use Select Case for this code:

Code:

---

Select Case B0
        Case 0:
                high led_1
                pause 100
                low led_1
                B0 = B0 + 1
        Case 1:
                high led_2
                pause 100
                low led_2
                B0 = B0 + 1
        Case Else
                high led_3
                pause 100
                low led_3
                B0 = 0
End Select
