i have some problems with reading Temperatur from LM75a over I2c.
I used the LPCXpresso LPC11C24 Development Board and the LM75A from NXP, Libary for LM75a from microBuilder.eu.

The wiring is i had checked.
When i start the projekt over the debugger i get one value from the lm75a, when i set a braikpoint and re-run it i get the next.
I thinked its an timing problem, (in the Datasheet from the lm75a writes that every 100ms read the registers)

Then i had insert a Task in the main-while, that every 200ms reading the registers from lm75a, but i have the same problem...

What am I doing wrong?

With best regards
