Re: will RTS reset BBB

DTR/RTS really sucks not because it doesn't work but because so many drivers and OSs handle it incorrectly. I've seen some say they use RTS and then really use DTR and visa versa. I do know that with Linux (Ubuntu) if you use the BUB board with the BBB "auto reset" works as needed to perform downloa...

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 analogWrite() only works on cert...

Re: Using AVRDUDE with BUB and BBB

I have both the same packages you have: Same WinAVR rev and the same rev of Arduino. While I did have to find the bootloader source code to identify the serial port speed, once I got the baud rate correct correct, I never had any trouble downloading nor did have to do hacking on any of the files or ...

So, it appears that the RBBB and BUB are working fine and that this particular 168 chip is doing something weird since it cripples what ever board it's plugged into.
Doesn't the RBBB come with a 328p ?

328p uses a different baud rate than 168.

Re: BBB and USBprog

So you are wanting to use the USBprog with a BBB? Where does the BUB come into this? I had a quick look at the USBprog site. Before going any further you may want to verify that it can do what might be needed on a BBB board. The avr ISP2 "clone" page does not list either the atmega168 or atmega328p ...

Re: New Forum & Connection FAQ

I assume the download works the first time you download after booting the system, but then additional downloads fail to work. This sounds like an auto-reset problem. I don't use any of the arduino code but I do use avrdude. I went through this same problem with the BUB and BBB board. It wasn't a har...

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 ...

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!

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 from Adobe R...
