Controlling diode array
wanna b inventor
Posts: 2
·I am trying to create an array of 16 x 16 individually controlled LED's using EEPROM's in·a single socket which can be swapped out in order to run different programs to create different displays on the LED array. With my BS2 I have 16 I/O ports which I plan on having each send out serial data to some sort of addressable component, which in turn would take a 16 bit word and light the LED's of its row that the program specifies.
·My questions are...
·1. What component is addressable & can pass the bits to individual outputs? (Someone mentioned multiplexer's to me, but I have never worked with them before.),
·2.·Are there any projects available that I would be able to learn this from?
·Thank you for any advice...I am new at this.

·· I think the best part for the task would be a 74HC595, or rather, a pair of them, if you're driving this with the BASIC Stamp.· You could generate different 16-bit addresses using those.
