bitfogav's proto board

Gav wanted to make a board that gave access to all of the data pins and use a LCD display for prototyping. Using Diptrace he designed a schematic and got to it. Read the full article to see how he did it along with schematics and source code.

Very nice - looks sharp!

Did you mill the board?

Can you post a schematic?
I like your layout.
curious about the LCD connections etc.

Thank you Jon, I used etching chemicals and Press and Peel to make the printed circuits on the copper.

Heres how I connected the LCD on my board using this Pin configuration

Looks good - nice job.

Am I the only one left using breadboard?? Seems everyone who's anyone has their own custom-made development board these days - I'm feeling a little left out

Personally, I'm a nobody on the first order, but I do not use homebrew Dev board, though I do have the iron on sheets to do such

It's just a hobby just adds more to it. I like pref boards.

This was my first try I made it from a piece of copper I found It was a ground plane and I turned it into my gpio buddy

Just curious as to why you used RB0 and RB1 for E & RW.
I know the data lines must be one same port but have seen several different configurations for the E and RW pins?
just curious and have to ask.
AndyO needs to get on the bandwagon!

Here's my development board. It can handle pretty much every PIC (including those that haven't been invented yet) and has a near infinite number of configurations Power comes from a 6-20V AC/DC supply or the USB port.


Also pictured are my 4 x 20 LCD, keypad, and RS232 "add-ons". I need to put together a little I/O board like be80be's - at the moment the 4 pushbuttons and LEDs in the bottom right corner of the breadboard are used but they take up a bit of space.

Hi MrDeb.

I actually used PORTE for my RS and E lines of the LCD, the RW line is actually going stright to ground which saves one more data line on the microchip.

I used PORTE has usually on a 40pin microchip PORTE is only usually a 3 or 4 pin PORT.
