Any answer to this?

When I hit "Compile Program" it compiles and opens up the programmer. Then I have to hit Program, in the programmer software. It used to program automatically, ie by itself. What am I doing wrong?

Commented out the lines...

ARRAYWRITE LCD_Buff,[" LCD PCF8574"] : LCD_WriteBuff

and

ARRAYWRITE LCD_Buff,[$FE,$C0,"Count = ",DEC LoopCount," "] : LCD_WriteBuff

Changed the $9D to a $C0...

Thanks to everyone that helped out.

I have gotten a modified version of Darrel's code to run on a 12F683 which has 2K of memory. :D

I am using an LCD 1602 and I don't see any Jumping Jacks.

Hmmm, unfortunately, I just figured out that my Silver version of PBP3.0 doesn't support the 12F1822...

Here is the thread in which I believe Darrel was using a 12F1822.

I believe Darrel Taylor was using a 12F1822. Doesn't that have the same "bit core" as my 12F629?

According to the Microchip datasheet on the 12F1822,

EarlyBird2, your reply has helped me understand this a bit more. I was able to get the norohs code to work without the initial I2CWRITE command as you suggested.

Darrel Taylor's program seems to...

Hmm, I am still having difficulty with this even after reading the above referenced threads.

Great, thank you. Lots of information in those posts.

I believe this may be my first post to this forum...

Has anyone figured more of this out? I finally got my I2C serial adapter for the 1602 LCD to do something at least.
