Write Onewire data toa I2C memory / read ASCI

Ok, look at the info below. Most of it came from http://www.rentron.com/PicBasic/one-wire3.htm and your posted program.

This may not be the most elegant method, but it should give you a start. I still do not think there is any real value in adding all the "text" characters to the EEPROM, but that's a different story.

' Additional Variables
Cold_Bit		VAR temperature.Bit11	' Sign-Bit for +/- Temp. 1 = Below 0 deg C
Sign			VAR BYTE	' +/- sign for temp display
temperature_int		VAR BYTE	' integer part of temperature   
temperature_dec		VAR BYTE	' fractional part of temperature

' Temperature Readout and manipulation
OWIn DQ, 0, [temperature.LOWBYTE, temperature.HIGHBYTE, Skip 4, count_remain, count_per_c]

IF Cold_Bit = 0 THEN	' If Cold_Bit = 0, positive temperature
    Sign  = "+"
    temperature = temperature & $00FF	' Mask lower byte of temperature
    (((temperature >> 1) * 100) - 25) + (((count_per_c - count_remain) * 100) / count_per_c)
ELSE	' If Cold_Bit = 1, negative temperature
    Sign  = "-"
    temperature = temperature & $00FF	' Mask lower byte of temperature
    (((temperature >> 1) * 100) - 25) + (((count_per_c - count_remain) * 100) / count_per_c)
ENDIF

'separate interger part from decimal part
temperature_int = ((temperature DIG 4) * 10) + (temperature DIG 3)	' integer part of temperature
temperature_dec = ((temperature DIG 1) * 10) + (temperature DIG 0)	' fractional part of temperature

'write digits to EEPROM
i2cwrite I2CDAT, I2CCLK, $A0, 71,[(temperature DIG 4)+48]	'load EEPROM with integer part
pause 5
i2cwrite I2CDAT, I2CCLK, $A0, 72,[(temperature DIG 3)+48]	'load EEPROM with integer part
pause 5
i2cwrite I2CDAT, I2CCLK, $A0, 74,[(temperature DIG 2)+48]	'load EEPROM with decimal part
pause 5  
i2cwrite I2CDAT, I2CCLK, $A0, 75,[(temperature DIG 1)+48]	'load EEPROM with decimal part
pause 5

I think his problem is extracting the individual digits out of the byte values to display on the LED matrix's, by using DIG, and he hasn't figured that part out yet, which is why I suggested earlier since he's got an LCD, to play with that first and get used to everything (and to find out if his temp sensor is actually working in the first place). Then build it all back up to displaying the reading on the LED matrix.

Thank you for link . I do not find your example on this link . Tell me a link for it , or post all example .
I am looking for little time on this program ...and I see that they use LCD display with " DEC " command .
