Dot Matrix Clock – The Open Source Display

Recently, the open source becomes increasingly popular, especially among the home hobbyists. Many people regarding the open source as the genuine approach to the design, development and distribution of software, which is offering practically accessibility to software’s source code. Some people even consider open source as one of various possible design approaches. Beside that, others might seem it as a critical strategic element of their operations. Before open source became widely adopted, many developers and producers used a variety of phrases to describe the concept. Today, you’re going to have the chance to build a Dot Matrix Clock, which is related with the open source. For your information, the whole project is costing under $150. Here are the characteristics of the Dot Matrix Clock, which as: 40×16 display with two LEDs per pixel giving 1280 LEDs Constant Current LED sink chips (It is to prevent varying brightness problems with the display) PIC 18F4550 microcontroller running off the PLL on a 16 MHz oscillator giving 12MIPS throughput 41-pin high density board to board connector 4 buttons 8-bit parallel bus with CS,… Continue reading
