Re: Ethernet Shield and BBB

Paul: Thanks. I'm up and running OK now. See http://thatsgoodbob.dyndns.org:8246 for example of code running on your BBB with Ethernet Shield. I'm wondering if my initial problem had to do with the fact that I have the Ethernet Shield *under* the BBB. The shield has rather long pins that might have ...

Re: Ethernet Shield and BBB

OK - I'm up and running. Last thing that was holding me back from success was the "byte gateway() = ... " statement I put in the WAN IP address of my network (instead of 192.168.0.1) and now it works. I don't understand why, but it does. I wonder if there's a way around this, so Ethernet Shield does...

Re: Ethernet Shield and BBB

OK. My new Ethernet shield came today. I put male pins on BBB pins 8-13 plus ground. That's all I should need - right? (Plus power line) Plugged it into shield. Also connected +5V on Shield to BBB. Shield powers up. Loaded Example Chat Server pde. Lights on board blink periodically. From Windows cmd...

Ethernet Shield and BBB

Paul: I was looking at the ethernet shields described at http://www.arduino.cc/en/Main/ArduinoEthernetShield The digital pins on this item have a space (.05"?) between digital pins 7 and 8 as does the Diecemilanova boards. Your BBB boards do not have this space between pins 7 and 8. Can the above et...

Re: Writing to Pins 0 and 1

Thanks Paul. I made a prototype using pins 1-7 to drive the seven segment lines and pins 8-13 to select the 6 decades (via PNP transistors sequentially powering the six common anodes). Seems to work just fine. Am able to upload (download) code revisions to the BBB without having to remove any wires ...

Writing to Pins 0 and 1

If I do write to Pin0 and/or Pin1 on my Bare Bones Board, and someone give me a concrete example of what bad might happen? Could I make it so I would be unable to upload new programs to the board with my USB-BUB? I am trying to drive a seven segment LED display, and it would be convenient to do this...

Re: Current sourcing and sinking on Digital Output Pins

This is very helpful. Thank you. What I am going to try now is to multiplex six 7-segment LEDs directly off the output pins. With 1K ohm resistors connecting each of the seven segment lines (tied together) to D2-D7 (current sink), I will cycle (at 30Hz) thru each display's anode which I will have co...

Current sourcing and sinking on Digital Output Pins

I'm sorry, but I have not been able to find the answer to this question on the web. Am using BBB w/ Arduino Duemilanove / Atmega328. What is current sourcing capacity of an individual digital output pin (that is: pin connected to resistor connected to LED connected to ground)? Also what is current s...

Re: Code Library - Binary Counter

Paul: Thanks for the code you posted. I like it even better than teedious's (which I liked a lot). In particular, in yours, the digits change synchronously. I was noting minor artifacts in the teedious program for example during the transition from 5 to 6. As the bits get set, the right upper segmen...

Code Library - Binary Counter

Hi: I'm just getting started with my brand new BBB and Arduino. It just came off the soldering iron yesterday. Is there a library of popular code snippets that I may access so I don't have to re-invent the wheel? I'm trying to cycle ten output pins through 1024 binary numbers. Someone must've posted...
