No worries ;-) Since the "program the EEPROM via the GM5" is probably not gonna happen soon, DIP is a better choice. Although you can in-circuit program the EEPROM with 4 wires, too ;-)
Done and fully working. I flipped the page for your reading pleasure. The odd little construction at the top is my special way of working with the not-quite-so-smart choice of footprint for the eeprom. Will be fixed in the final version of course.
Updates: It's alive :D The attached images show (1) the minimum requirements with just the gm5 and the usb circuitry, (2) one fully assembled strip (due to a tiny little imperfection in the layout *cough* the sockets had to be mounted under the pcb).
What doesn't work? Do you have the correct toolchain installed? Do you get an error during compile or does the app simply not work? If you get an error - what does it say? Show some code! Give us some details to work with ;-)
Und da wußte ich dass das Posting gut wird :-) Recht hat er, ich hab auch schon einiges versucht, lohnt nicht. Und 'nen Gleichrichter, einen Spannungsregler und ein paar Kondensatoren würde ich nicht "das Rad neu erfinden" nennen.
