Problems with 16F684

[jellis00]

Sorry, fratello....I thought I could help you but I found out your code is setup for use only with the PM assembler which I can't use with my 64 bit machine. I can only use the MPASM assembler. Maybe someone else can help you test compile this.

Never mind...Thanks anyway for help !
Regards !

Hi fratello!
I tried to compile but I got :
Error UNTEST~.ASM 440: [235] opcode expected insted of 'error'

[fratello]

Strange ...
I have no errors on compiling...just not work !

[fratello]

With code from post #1, I build this thermo-voltmeter for using in car.
Note : for "I(nside)" I dont have anymore DS18B20 sensor...

Congratulation, Fratello!
Good work.

Hi, Fratello

I just think ISIS doesn't appreciate you do not wait for DS1820 temp conversion complete to continue running your code ...
not a real problem ( Mikroelektronika lets it as-is in its onewire drivers ... booooo )

in easy words, ....Change

Main :
 OWOut DQ1, 1, [$CC, $44] 
 OWOut DQ1, 1, [$CC, $BE]
 OWIn DQ1, 2, [temperature1.byte0, temperature1.byte1]

for

'*****************************************************************************
' Start temperature conversion
'*****************************************************************************
main:
 OWOut DQ1, 1, [$CC, $44 ]
'*****************************************************************************
' Check for still busy converting 
'*****************************************************************************
waitloop: 

 OWIn DQ1, 4, [Busy]        ' Check for still busy converting
 
 Pause 95         ' Slow Down to actual Conv. time
 
 If NOT Busy Then waitloop
  
'*****************************************************************************
' Read the temperature
'*****************************************************************************
 OWOut DQ1, 1, [$CC, $BE ]
 OWIn DQ1, 2, [temperature1.byte0, temperature1.byte1]

you will display the very last correct measurement and not get " 85°C" or junk at power up ...
