#90 - Datron 1071 LED display

I finally decided to try another approach for display replacement in this good old Datron 1071 meter. Design decisions are discussed in detail, and the code for ATmega164PA is shown. The new display is very bright with a very wide viewing angle, but it could use a better diffusing overlay.
