This is about the recycled displays that fluke.l used to implement his
version of the KO4BB Thunderbolt monitor and he sells on eBay.
I bought some of these iCruze surplus displays because I think that are
a good gadget for a variety of projects, since they include, among the
20 x 2 line back lit display, a nice cabinet and a good looking
bezel. My plan was to remove (or exchange) the pcb with the
microprocessor and keep only the display itself and the cabinet, more or
less as Bob (fluke.l) did.
Anyway I tried to know more about the original circuitry, because it
could be useful. Imagine if this is something like a serial ASCII
terminal. So I did some reverse engineering, found a signal leaving the
device and now I got the schematics.
It seems to communicate with I2C, but I'm not sure, it needs some
experimentation by someone used to this protocol.
Some members of this list already had bought several units and asked me
about the information, so I want to know a good place to upload if it
can be of interest to mere members, or I can send it directly to the
ones that has asked for it.
Regards,
Ignacio, EB4APL
