Little Wire AVR-ISP

Pedantite built his own Little Wire AVR programmer/tool:

The Attiny 85 has a neat feature that I had overlooked until I built this in that it has a built in PLL that lets you run the system off the internal RC oscillator at around 16Mhz. Many other AVR’s lack that PLL, and can only run at 8Mhz maximum without an external crystal.

Little Wire is multi-featured USB controlled open source hardware tool packed in a minimal form factor designed by Ihsan Kehribar. Even though it has minimal form factor, it’s packed with full of features. There aren’t any SMT components involved, so it is very suitable for beginners to assemble.

    Words cannot express my glee in stumbling across this entry in my feeds today :) D.P. is one of my favorite blogs, and an inspiration for what I wish my blog could be.

    All props must really go to the designers of Little Wire, USB Tiny, and VUSB. This thing has become a “daily driver” for meeting my AVR/ISP needs.

    –P

    Does anybody ACTUALLY works with LittleWire?
    The internet is VOID of any software project using LittleWire.
    No, blinking LED is not a project!
    BTW I got it working with DDS AD9850 and would like to hear from anybody who can discus timing issues I had implementing simple three wire ( LOAD, DATA,CLOCK) “protocol”.
    I ended up with clock of 5 ms , clocking device which is capable of microseconds clocking.
    I have no issue with this “speed” , just like to know why LittleWire is so poky.
