Hello World. I have an question about 7 pushbuttons on one ADC port the buttons have it's one resistor as a pull-up. the button connect the resister to the ground, that gifs an value on the ADC port look by low Sub _buttons If Vin = 450 Then Volt = Volt + 1 Elseif Vin = 130 Then Volt = Volt - 1 Elseif Vin = 3 Then Volt = 0 Elseif Vin = 841 Then Amp = Amp + 1 Elseif Vin = 609 Then Amp = Amp - 1 Elseif Vin = 3 Then Amp = 0 End If End Sub but now it's it comes. when my Atmel is going warmer the value deviates and the buttons doen't work any more. because the value is not 451 but 450 or 449 there is a solution for this problem Can it may be with a margin that it looks from 840 to 843 example.... thanx [b:e63ff51f9c][color=red:e63ff51f9c](BASCOM-AVR version : 2.0.7.6 )[/b:e63ff51f9c][/color:e63ff51f9c]
