I2C write - value too big

[ruijc]

Hi all,

i have found a bug in my temperature logger (16F88 + 24LC512+LM35).
I works pretty well until it reaches temp values of 124ºC, for values above it are displayed as 0ºC or 0,5ºC.

I've looked at my code and i think a know what the problem is: I need to separate the variable into lowbyte and highbyte.

The problem is that i'm not being able to get this working that way. Here's why :


This way does not work:

I2CWRITE SDA,SCL,CTW,ADDR,[tempe.highbyte]
pause 10
ADDR=ADDR+1
I2CWRITE SDA,SCL,CTW,ADDR,[tempe.lowbyte]

This way does not work:

I2CWRITE SDA,SCL,CTW,ADDR.highbyte,addr.lowbyte,[tempe.highbyte]
pause 10    
ADDR=ADDR+1
I2CWRITE SDA,SCL,CTW,ADDR.highbyte,addr.lowbyte,[tempe.LOWBYTE]

Only this way one works:

I2CWRITE SDA,SCL,CTW,ADDR.highbyte,addr.lowbyte,[tempe]
pause 10    
ADDR=ADDR+1
I2CWRITE SDA,SCL,CTW,ADDR.highbyte,addr.lowbyte,[tempe]

Long story short:
I can make it work with the eeprom BUT only with Address high and low. If i try to separate the variable tempe into high and low it doesnt work

Any ideas ?
Thanks
