Hello.

I try use LM75 I2C Temperature sensor on LPC Xpresso 1769 board. I wanna read temperature and save to variable, bud i cant find working example. I tried to use I2C example from this: https://www.lpcware.com/content/nxpfile/mcb1700-sample-code-bundle-lpc1769-peripherals-using-lpcxpresso but program no built. Maybe somebodys have working example or idea how do this?

Thank you.
Maybe is example for something another, when in main function i can change adress device. i found this: http://www.brc-electronics.nl/librarys/108-interfacing/i-c/lm75 but i cant find working includes for this project. I can built this, but this dont working correctly.

So did you check your hardware? Did you scope your I2C lines?

Yes. I think problem is in my program. Maybe somebodys have working example for I2C where i can change device adress? Now i am trying to run example from therehttps://www.lpcware.com/content/nxpfile/mcb1700-sample-code-bundle-lpc1769-peripherals-using-lpcxpresso, but is problem whith built this.
