I would read temperature from TC74 temperature sensor with PIC16F84 and LCD display.

This is my code



SCL var PORTA.3

SDA var PORTA.4

TEMP var BYTE



MAIN:

PAUSE 1000

I2CWRITE SDA, SCL, $9A, $1, [$00]

I2CREAD SDA, SCL, $9A, $0, [TEMP], NOREAD

GOTO OK

NOREAD:

LCDOUT $FE, 1

LCDOUT “NOREAD”

GOTO MAIN

OK:

LCDOUT $FE, 1

LCDOUT “TEMPERATURE= “, #TEMP

GOTO MAIN

END





I don’t know why the display always screen “noread”….. i have verified the connections and it seems ok.... please HELP!!!!!
