The main goal was to increase the frequency range but maintaining the cheapest cost. Large and inexpensive color display has been used. Drzasiek wanted build a mobile device, so he was looking for small elements.
Please share me a low cost easy atmega 128 Programmer or Jtag schematic with Programming Software.
Hi Every Body Do you know how to build simple atmega 128 Programmer. I Have tried STK200/300 Schematic (Interfaced with LPT ) But I had Used 74LS244 instead of 74HC244 .But It Doesn't work.
