Posted on January 31st, 2013 BeagleBone GPIO
Today I experimented with GPIO on the BeagleBone. After placing the BeagleBone inside a Lock & Lock container with a breadboard I wired up 4 LED. Each LED is driven by a transistor which in turn is driven by a GPIO pin. I used the Debian “Wheezy” install to conduct this experiment

Posted on January 30th, 2013 In my previous post about the BeagleBone I described how I installed Debian “Squeeze”. I had tried Debian “Wheezy” but it failed. Today I retried the install of Debian “Wheezy” with the difference being of using a 4GB micro SD card. Installing a different Debian release is very simple, just replace the mk_mmc.sh command with

I finally ventured into the world of embedded ARM and Linux on ARM. Having done a good share of embedded Intel i386 projects I am no stranger to embedded Linux. But it is my first adventure into the world of non-Intel Linux. I’ve looked at the Raspberry Pi but it has been an

The *uino-1284p assembled
Over the past few days I assembled one each of the *uino-1284p and *uino-32u4. Things went very well and few issues were encountered.
The *uino-32u4 went together flawless. For initial testing I used the Arduino Leonardo bootloader and core files. Since my pinout differs from the Arduino Leonardo this required some translating

The *uino-1284p v0.2 PCB Top
Today I received more *uino-1284p boards. The other day I already received *uino-1284p boards. Those boards were version 0.3 boards. The boards received today are the predecessor, version 0.2. I have been discussing my ATmega1284p ideas on the Arduino Forum. I had thought that what I accomplished with this

The *uino-1284p v0.3 PCB Top
Here it is! The *uino-1284p has arrived. It is an Arduino compatible platform based on the ATmega1284P-AU. The *uino-1284p board utilizes the ATmega1284P microcontroller. The primary goal of this project is to be able to access more memory, FLASH and RAM, while keeping the Arduino UNO compatible board size

Posted on January 13th, 2012 The *uino-32u4 Circuit Board Order
I have already written about the ATmega32U4 based *uino-32u4 I’ve created. Today I received the circuit board order. The order was placed with Seeed Studio’s Fusion PCB Service on December 24, 2011 and arrived at my door on January 13, 2012. I am impressed, at the speedy service and

Posted on January 7th, 2012 For some reason I had an ATmega168 and an ATmega328 sitting in my parts bins. To put them to use a couple bare PCB were ordered from a Chinese vendor on eBay. The boards I received were in superb condition. Most surface mount components were 0805 size, except for the FDTI chip of course.

*uino-32u4
I have been thinking about some electronics projects again. While looking at processors and other details I discovered Arduino and also the Arduino compatible chipKit UNO32. These are some pretty neat devices which come with a development platform that runs on Windows, Linux and Mac OS X.
Instead of buying an original Arduino

Posted on November 12th, 2006 The Atmel AVR Dragon is a new programmer for Atmel AVR 8-bit Microcontrollers. I obtained this little beast because my old AVRISP serial programmer was useless due to lack of serial hardware on my PC. The Dragon was quite inexpensive and readily available at DigiKey. It promised to not only provide ISP (In-circuit Serial Programming),
