  • A good stubby phillips.

    Whenever I look at integrating avrdude into a software solution I find myself thingking about how useless the “Phillip”s bit on a Leatherman(tm) tool is and how many times I have hurt myself using it when it was the tool on hand.

  • Benito changes.

    One of the benefits of having laens pcb order available is that I can test design changes iteratively and explore other possibilities. The benitos i am using in the induction this month are the result of three iterative changes based on the original Benito and a redesign done by Monty Goodson a few years back. […]

    Foobarred is Normal Recently I started using my linux laptop as my primary avr-usb development environment. When I upgraded the laptop to the current Ubuntu-LTS release (10.4 aka Lucid lynx) a bunch of stuff was broken including all of the wonderful udev rules provided by my linux savvy friends at dorkbotpdx. I mean jeesh even […]

  • Running Paul Stoffregons’s teensy_serial arduino core on DFU based chips.

    With a lot of my projects I have done my prototyping with Paul Stoffregon’s Teensy series of boards before moving them onto their own codebases. On those occasions where the “prototype was all I needed” I would compile the code using the teensyduino and then manually load the .hex file onto the target. As I […]

    The testbox is an LCD/Dorkboard based arduino clone with two buttons and a pair of potentiometers. The switches, power and 4 io pins are made avaliable via screw terminals on the ouside of the testbox. #include /*————————————————————– pulse generator for test box Depending on the setting of left dial send send pulses out on digital […]

  • Reprogramming your avr-usb device using atmel’s built in bootloader

    Getting code onto the MidiMonster or Benito device. All of the code on the Benito and MidiMonster devices is open source and references an open source library called the Lightweight Usb For Avr (lufa). Getting the code compiled and onto the device requires a few other open source tools. AVR-GCC The most current and stable […]
