I2C-Libary for MSP430F16x

[mgiaco82]

Hello, I have started to write a Libary for the Hardware Modul of the MSP430F16x and I have some problems with it.

I want to read from a LM75 and I can only read the high byte.
I wrote something like this.

i2c_start(SLAVE1);

temp0 = i2c_readAck();
lcd_puts_int(temp0,0,1);

temp1 = i2c_readAck();
lcd_puts_int(temp1,0,2);

And then I get.:

23
23

on my LCD, and not

23
128 or something like else

I think there is some wrong i my lib.

please have a look on it.
