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,
"This family of devices contains an...
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.
It was indeed very...
