Hi,
I'm somewhat affraid ...
0 < Tb0 < 1024 ... ok ?ADCIN 1,tb0
tb1=tb0-16170
tb1=tb1*tb3
tb2=Div32 634
tb0=tb2/100
tb1=tb2//100
1024 - 16170 = ??? - 15146 !!!
so, tb1 is NEGATIVE ...
and PBP do not deal with negative numbers .... but " read " it as 65536 -15146 = ???
a hole in the somewhere ???

Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

IF there is the word "Problem" in your question ...
certainly the answer is " RTFM " or " RTFDataSheet " !!!

Well, the ADC range is not 0-1024, but 0-65535...Originally Posted by Acetronics

(verified with a display of the raw ADC value).

Alain never said the ADC range was 0 - 65535.
He was telling you how the value would be acted on.

You should place a patent on this one ...
Hurry up !!!
Alain
PS you do not display Tb0 ( as the ADC result ) , but Tb0 ( after - false - calculations done ! ) ....

In case you are wondering why, the ADC is 10 bit, so clearly you can't have 16 bit result from the ADCYou should place a patent on this one ...

The glass is not half full or half empty, Its twice as big as needed for the job!

It's weird. I got a 16-bit result. Why? Code :
Code:define OSC 20 DEFINE ADC_BITS 10 DEFINE ADC_CLOCK 3 DEFINE ADC_SAMPLEUS 10 DEFINE LCD_DREG PORTC DEFINE LCD_RSREG PORTC DEFINE LCD_EREG PORTC DEFINE LCD_EBIT 5 DEFINE LCD_COMMANDUS 10000'Command delay time in us DEFINE LCD_DATAUS 1000 'Data delay time in us ntc VAR WORD TRISA=%11111111 ADCON1=%10000010 PAUSE 4000 lp: ADCIN 1,ntc PAUSE 100 Lcdout $fe,$c0,#ntc goto lpAnd what are the differences between Tb0 and Tb0? I didn't understand your answer.you do not display Tb0 ( as the ADC result ) , but Tb0

Never trust a sim.
Try it in real life and come back.

see any difference between Tb0 value @ line 1 and Tb0 Value @ line 5 ???ADCIN 1,tb0
tb1=tb0-16170
tb1=tb1*tb3
tb2=Div32 634
tb0=tb2/100
tb1=tb2//100
really no ?

But this time I think the sim is correct. I think you ment to set ADCON2, not ADCON1. ADCON 2 sets right or left justified. Default is left justified.
