I get the two bars when in the programing mode but when I switch to the program I get a blank LCD.

Any ideas?

This has been working great.

Hi Ralph,

I would check the battery, as well as the wires going to the LCD (and the rest of them while you are at it). It is much likelier that something came loose than the program suddenly disappearing.

How wold I know if the program was loaded if it will not run??

All of the wires are in place! I switched the MCU and got the same two bars but after turning the power off and pulling and reinstalling the new MCU the program runs.

Did I fry the first MCU?

I had tried loading a program that I typed and had gotten compiler errors but eventually the compiler ran normally.

Now with my second MCU I am getting the same results after loading a program.

The Make runs successfully through all of the steps.

This was running the NerdKit greeting before running Make, so it s wired correctly.

and now I have the LCD to be blank when the switch is in the run position.

I have the two bars when in the programing position.

The wiring is correct I run the NerdKits greeting program successfully with a new MCU.

oh gee surprise surprise, my problem was with Windows7.

I installed the tempsensor program from my tablet running XP and everything works correctly.

Only wasted three days on this, thanks microsoft.

Did you know that the Timer/Counter modules on the microcontroller can be configured to output a PWM (Pulse Width Modulation) signal? Learn more...
