Designing a suitable LED display
for a particular application can be
time consuming. In particular, the decoder
that sits between the driver circuit
and the display often needs to be
made to measure. The main advantage
of the circuit presented here is that the
same hardware can be used to iImplement
many different types of display
decoding. This is achieved by using an
EPROM, which most readers will be
able to program or have programmed.
