One more thing ...
The compiler doesn't like " ° " ( "Maj" + "=" ) character ...
better use
where 223 ( sometimes 178 ) is supposed to be the ASCII code of " ° " ...Code:Lcdout $FE,$C0,"ITS: ",DEC3 tb0,".",DEC2 tb1, 223, "C"
That said ... ADC value NEVER is > 1023 ...
from your firsts explanations ( post #1) ... I get That : ( 16F877A on EasyPic5 )
Gives me a 0 - 100°C scale for adc = 67 to 1023 ...Code:DEFINE ADC_BITS 10 ' Set number of bits in result DEFINE LCD_DREG PORTB ' Set LCD Data port DEFINE LCD_DBIT 0 ' Set starting Data bit (0 or 4) if 4-bit bus .7 DEFINE LCD_RSREG PORTB ' Set LCD Register Select port DEFINE LCD_RSBIT 4 ' Set LCD Register Select bit DEFINE LCD_EREG PORTB ' Set LCD Enable port DEFINE LCD_EBIT 5 ' Set LCD Enable bit i.e, PORTE.4 DEFINE LCD_BITS 4 ' Set LCD bus size ot 4 bit Upper Nibble (4 or 8 bits) DEFINE LCD_LINES 2 ' Set number of lines on LCD to 4 Lines TRISA = %11111111 TRISB = 0 TRISC = 0 CMCON = 7 ADCON0 = %11000001 ADCON1 = %10000100 ntc VAR WORD tb0 VAR WORD tb1 VAR WORD tb2 VAR WORD PAUSE 700 LCDOUT $fe,1 lp: ADCIN 1,ntc tb0 = ntc * 33 /92 tb1 = tb0*721 tb2 = Div32 255 tb2 = tb2 - 64 tb0 = tb2/10 tb1 = tb2//10 PAUSE 200 LCDOUT $FE,2,DEC4 ntc Lcdout $FE,$C0,"ITS: ",DEC3 tb0,".",DEC1 tb1,178,"C" goto lp
so, i suppose it to be " not so bad , but to confirm "
