Trouble with LCD 2x8 and sequential display of values

[gadelhas]

Can you attache the files? ( your code and elapsed.bas)

Thanks again for support !

I copied your code, and i can not see that error, however, instead of the;

@ INT_DISABLE   TMR1_INT

 '1 wire stuff

@ INT_ENABLE   TMR1_INT

try this;

    T1CON.0 = 0                   ; Turn OFF Timer1

 '1 wire stuff

    T1CON.0 = 1                   ; Turn ON Timer1

[fratello]

I tried this way, but...the timer stop counting (so, I can't display 5 sec. IN and 5 sec. OUT) and the reading of sensor(s) it's not continous....like in my "original" code ...
I want to read permanent the sensors (for sensing the variation of temperatures) and display the temperature, 5 seconds from first sensor, the next 5 seconds from second sensor, so on, so on ....
Otherwise I can write the code like this :
" display temperature 1
pause 5000
display temperature 2
pause 5000
goto loop "
which is not a good option ...
