Re: GLCD Fun
Ok, so things drug out way longer than expected. But a Beta version of a new Arduino GLCD library is available. See this arduino thread for details: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1279128237/ A tremendous amount of work and effort was put in to add new features, make it easy to conf...

Re: Arduino pins
For the ultimate answer consult the actual source code:
http://code.google.com/p/arduino/source ... _arduino.c
All the arduino pin functions use table lookups to map the naked constants to a port and a bit.

Re: Arduino proto board
You could always use a teensy board: http://www.pjrc.com/teensy/index.html
directly on a protoboard. I use them with header pins and put female headers on the protoboard.
That way I can transfer a breadboard design directly to a protoboard.
Same thing I do with the BBB boards.

Re: Arduino proto board
I don't have any yet, but one of the things that I really like is that along the side of those as well as some of their other prototype boards, is 20 holes for connections. This is great for hooking up things like 16 pin LCDs and even 20 pin GLCDs. You could put female headers on the proto board, an...

Re: Arduino pins
Then there is also analogWrite(pin, val) where pin is a "digital" pin#. vs analogRead(pin) where pin# is a "analog" pin#. So analogWrite() and analogRead() are referring to two different physical AVR pins but yet use the same pin# "token". Complicating things is that an...

Re: GLCD Fun
Guys, I haven't forgotten about this. Much work has been done and good things are happening. I am working with Michael Margolis on an arduino glcd library. He already had one: http://www.arduino.cc/playground/Code/GLCDks0108 I have enhanced it by updating the low level h/w access routines to make it...

Re: BBB pin overlay card for non Arduino users
BINGO! Here is a simple way to use the existing card for both the bingo card and a pin overlay and still do single side printing. Having the full bingo card is actually kind of nice as you can hold the card up to your breadboard to make sure you didn't offset your wires. Users who want the pin overl...

Re: BBB pin overlay card for non Arduino users
Thanks Bill, it's a nice eco-friendly idea - I guess it would depend on how well my printer will register when printing on the backside - and also how opaque the paper is for two-sided print job. Experiments in order. Paul I understand the need to keep labor and material costs down, thats why for t...

Re: Need suggestions for a project...
How many LEDs are you trying to control? You can control up to 120 on a m168/m328p and still use the 2 pins for serial communication. The trick is to think multiplexed where not all of them are lit at the same time and to use a column and row addressing scheme. To get to 120 you have to cheat a bit ...

Re: BBB pin overlay card for non Arduino users
We've got a fab lab here now - I might try and stack a few up on card stock and see if it can get through 10 at a time. Good give-aways! Thanks again for your efforts Bill So does it come out die cut or is this just for printing? I was thinking that there is enough room on the existing cardstock ca...

Re: BBB pin overlay card for non Arduino users
Attached is a zip file with the latest BBB pin overlay card.
There are two files in the archive.
A PDF image and the original OpenOffice writer document used to create it.
See previous post for how to print it and avoid scaling issues.
Enjoy,

Re: BBB pin overlay card for non Arduino users
Ok, so I finally decided to create what I think is a properly scaled PDF image. There are so many different components in Windows that try to make your life "easier" by doing auto scaling that this turned out be more difficult than it should have. At least for me now, if I print the PDF fr...

Re: GLCD Fun
slows down the code by having to do SBI/CBI instructions for every single bit For flexibility I have decided not to try to keep the data bits on a single port any more. I just write my code to set the bits individually using SBI/CBI all the time. For the worst case it takes 6 clock cycles to set up...

Re: GLCD Fun
Don, That's Very Cool. One thing I did differently was to skip over the Tx/Rx (D0 & D1) to allow use of the serial port concurrently with the GLCD. That's why I had to have 2 wires going over to the analog pins. The analog pins are for DI and RESET. All the other pins were run straight across. T...

Re: small updates for next BBB PCB.
When I decided to include inductor I looked around for a small unit and also the right price and didn't find any through-hole parts that fit the bill. I understand, as this is a cost sensitive product. But perhaps it could be an order option where you charge say an extra $1.00 for those that want t...

small updates for next BBB PCB.
Paul, I have to say I love the BBB board. From the nice light PCB color with the easy to read labels to its ease of use for prototyping. If you ever do respin the BBB board for some reason, here are a few tiny things that perhaps might be worth considering. - Make ISP power line larger In some cases...

Re: v-usb boot loaders mega168 compatible
Paul, I've seen sample projects with the V-usb/USBTiny stuff working on ATtiny45s with no crystal. Really nice for that environment as you can get a full USB serial connection to the host using the serial CDC without needing any additional USB->serial hardware. So it definitely could work on somethi...
