Some updates

A project log for DYPLED

a thin LED display in SIP module format, much better than TIL311s to visualise your computer buses

Here are the latest news :-)

I will use warm white LEDs for the segments, so they are easier for the eyes.

I fixed the blanking system to avoid power drain when grounded.

I found the reel of double Schottky diodes (it was hiding with the transistors, hey it's SOT23 too...)

I've refined the mode displays : 0603 LEDs with very dim light and different colors (the current mode is easier to visualise, color is faster to "grasp" than precise position)

I'm entering the schematics in EAGLE and checking all the parts, their pinout, their footprints, prices, availability and values...

What's left ?

- get/make the footprint for the flat SMD pushbuttons

- check the phases and the decimal decoder

- layout

- mix/swap all the inputs and outputs for easier routing

- create a program that generates the flash's contents according to the routing matrix

and so on...
