How to make a word as decimal in if then else statement

[jeroeni]

Yeah, I'm using the pro version.

Your lines look to be an uncontrolled mix of Basic and C languages ...

So, it will be rather difficult to help you ...

BTW "Jeroen" ... that reminds me something...
what's your mother language ???

I'd bet Dutch ...

[jeroeni]

You're correct. I'm from Holland, a dutch guy...

[jeroeni]

I will explain what I am trying to do... maybe it helps... in bad english, lol

I've got 2 components, a DS1820 and a simple LED, both on other ports.
When the DS1820 gets on 21,2celcius for example, the LED must blink, on 21,2+ the LED stays on, on 21,2- the LED turns off. The code I've got to control the DS1820 is:

Above clear:
SYMBOL Convert      = $44 
SYMBOL RdScratchPad = $BE
SYMBOL SkipROM      = $CC
SYMBOL Graad        = 223    
SYMBOL DS1820       = PORTA.1
SYMBOL verwarming   = PORTA.6

DIM Temp            AS WORD
DIM Remain          AS BYTE
DIM Slope           AS BYTE
DIM BD1             AS BYTE   

--------

  OWRITE DS1820, 1, [SkipROM, Convert]
  OWRITE DS1820, 1, [SkipROM, RdScratchPad]
  OREAD  DS1820, 2, [Temp.LOWBYTE, Temp.HIGHBYTE, BD1, BD1, BD1, BD1, Remain, Slope] ',CRC]
 
  Temp = (((Temp >> 1) * 100) - 25) + (((Slope - Remain) * 100) / Slope)                
                                                                
  PRINT AT 1, 1, DEC Temp / 100, ".", DEC1 Temp / 10, Graad, "C  "

[edit]
by the way, verwarming is dutch... but doens't mather... it's just a symbol
[/edit]
But how can i control the LED with the code above? I used a IF then ELSE statement on Temp but Temp shows only symbols (not with DEC in front of it at the PRINT line, so not on LCD with that code)

[edit2]
When i use this, just for example what Temp do without DEC, I get the most funnyest symbols and icons on LCD

  PRINT AT 1, 1, Temp

Anyhow... I need to put it in a If then Else statement... to control the led

Try to use PBP commands for the words I've put in RED ...

Will work much better ... ... IF YOU USE PICBASIC PRO, WHICH IS NOT THE CASE ...

[mister_e]

calm down Alain

jeroeni seems you're using another variant of PICBasic compiler, to me it looks like Proton Picbasic whose forum is located at the following link

Hi, Steve

Sorry ... I couldn't recognise this one ... which is running fine.

' One-wire temperature for PROTON Board and DS1820
Include "PROTON_4.INC"
 
Dim Temperature As Word ' Temperature storage
Dim Count_remain As Byte ' Count remaining
Dim Count_per_c As Byte ' Count per degree C
Dim Dum As Byte ' Dummy variable to pad OWIN
Symbol DQ = PORTC.0 ' One-wire data pin
DelayMS 500 ' Wait for PICmicro to stabilise
Cls
Mainloop: 
OWrite DQ, 1, [$CC, $44] ' Start temperature conversion
While ORead DQ, 4 = 0 : Wend ' Check for still busy converting
OWrite DQ, 1, [$CC, $BE] ' Read the Temperature
ORead DQ, 0, [Temperature.LowByte, Temperature.HighByte, Dum,Dum,Dum,Dum, Count_remain, Count_per_c]
' Calculate temperature in degrees C to 2 decimal places (not valid for negative temperature)
Temperature = (((Temperature >> 1) * 100) - 25) + (((Count_per_c - Count_remain) * 100) / Count_per_c)
Print $FE, 1, Dec (Temperature / 100), ".", Dec2 Temperature, " C"
' Calculate temperature in degrees F to 2 decimal places (not valid for negative temperature)
Temperature = (Temperature */ 461) + 3200
Print $FE, $C0, Dec (Temperature / 100), ".", Dec2 Temperature, " F"
DelayMS 1000 ' Display once a second
GoTo Mainloop ' Do it forever

Are you using Pic Basic (PRO) ?

jeroeni

Yeah, I'm using the pro version

Ok, Ok ...
