Hello

I am making a simple pressure sensor all works fine.
i get the output reading as XX.XXX on a 16x2 LCD

i want only the XX before the decimal to be displayed. Help please.

Code:

Dim Pressure as Single

displaypressure:
        Adcin 0, analogread
        pressure = analogread * 5.0 / 1024
        pressure = (pressure - 0.54) / 0.059
        Lcdcmdout LcdLine1Clear
        Lcdcmdout LcdLine1Home
        Lcdout "PRESSURE", ":", " ", " ", #pressure
Return

cheers

• int r(float f) {

• int result = f;

• return result; // You could just write "return f;" instead.

• }

the pressure you are getting is an analog thing you want to convert it to a digital thing
try this:

• int r(float f) {
• int result = f;
• return result; // You could just write "return f;" instead.
• }

This should work.
Define SINGLE_DECIMAL_PLACES=0

I would try to cast... example..

Code:

Dim Pressure as Single
Dim DispPressure as word

displaypressure:
        Adcin 0, analogread
        pressure = analogread * 5.0 / 1024
        pressure = (Pressure - 0.54) / 0.059
        DispPressure = Pressure
        Lcdcmdout LcdLine1Clear
        Lcdcmdout LcdLine1Home
        Lcdout "PRESSURE", ":", " ", " ", #DispPressure
Return

That should get rid of the floating points..Untested ..Try it.
