This same code worked when compiled on my PC but fails when compiled on OSX.

Well actually it seems to compile fine it is just a incomplete display on the LCD.

I get:

     ADC:     154    of     1024
     F

That's it no temperature is displayed.

Thanks for the help, Ralph

Hi Ralph,

Did you remember to run "avr-gcc-select 4" from the Terminal? If you run this, then remove all of the .o and .hex files from your tempsensor and libnerdkits directories. Then, run "make" again, so it will compile it with the right compiler version. Post back after you give this a try.

What is avr-gcc-select 4? Where do i get it? How would I "run" it? Yes I know next to nothing :-)

Thanks, Ralph

Ok I ran "avr-gcc-select 4" from Terminal (where was it ever said to do this?).

miniMac:tempsensor Me$ avr-gcc-select 4

Current default compiler: gcc 4

I still get the same results.

Thanks for the help, Ralph

Hi Ralph,

After running that command, you now have to delete any files ending in .o or .hex in your tempsensor and libnerdkits directories. Otherwise, it won't bother trying to recompile it, and will just re-upload the old version.

All right, thank you Mike, I got it to run (doing exactly as you said).

Thanks again, Ralph
