DMD: Dot Matrix Display 32x16

LED Dot matrix display Driver

The Siemens DLO7135 Dot matrix LED is just one amazing bit of optoelectronics. It is billed as a 5x7 Dot Matrix Intelligent show (r) with Memory/Decoder/Driver. Along side that memory, it's a 96-character ASCII screen set with top and lower case characters, an integrated personality generator and multiplexer, four quantities of light intensity, therefore all works on 5V.

That is too much to meet, as well as $16 a pop, it definitely should. While investing half your day within my preferred neighborhood electronics store i came across a bin saturated in these for $1.50 an item. I left the store with a number of.

This instructable will show you simple tips to connect to these dot matrix LED's and display characters making use of an AVR-based Arduino. If you've read some of my earlier guides, you can find the concept that I'm usually in favor of the essential parsimonious answer, and also you would not be incorrect, just because I do fall short of the goal from time to time. For that reason, I'll additionally get another step up this instructable and explain to you how you can lower the number of I/O harbors necessary to drive these big, honkin' dot matrix LED's.
