New to this Need documentation for the Penguin

KAKA

Is there documentation specifically for the Penguin?· For example, I don't understand how the 7 segment LED is connected with only four pins?· I don't know PBASIC but did write a quick program to pull each pin low....result was odd segments displayed.· I don't know PBASIC.· Are there programs of varying complexity in a location some where.

As is true for most Parallax products, the webstore page for the Penguin has links to documentation for it including circuit diagrams that show how the LED is connected. There's a host of programs written for it. Start with the Penguin Tech thread in this (Robotics) forum. You will have to learn PBasic. Download the manual and the "What's a Microcontroller?" tutorial. Go to the main Parallax webpage, choose the Resources tab, then the Downloads item. You'll see links for Stamps in Class Downloads for the tutorials and Basic Stamp Documentation for the manual.

Thanks I see the LS47 now.......makes more sense for the display at least!

KAKA, I'm putting together documentation on programming
the Penguin Robot 7-segment display, and will publish it in
Penguin Tech and post it in the forum when complete.

At a glance, I see 5 different techniques of programming it,
some of which are more explanatory and some less. You've
certainly come across one way to set the display, using
four pins, highs and lows.

The odd segments you discovered are actually graphic
characters, of which a total of 5 can be accessed. There's
at least one very peculiar graphic. More on that later.

The remaining are digits from 0 to 9. Follow Mike's suggestion
as there are 22 Penguin programs posted that involve use
of the segment display - the locations are printed in
Penguin Tech Magazine Issue #1 found here.

The display related programs are listed below. Keep in mind
that three new techniques will be introduced shortly. I think
this is everything as I'm working from my own memory and
the actual file names may be slightly different. I hope this is
a good start for you.
