High Power Multiplexed Seven Segment LED Display Driver

One of the most common place where small MCUs are used is to drive big seven segment displays in public area. For example the bank token number, flight or train schedule, train coach number, production volume (in factories), current forex(in banks) or gold rates etc. Since these are public display they should be big (and bright) enough to be seen from a distance of few meters. And due to their bigger size(and high brightness) they require 12V supply for each segments. Current requirement is also high. All these call for a sophisticated circuit, since these type of circuit is very common we have developed a compact board with integrated high voltage driver circuit coupled with an AVR 8 bit CPU. High Voltage Seven Segment Display Driver Board Further information, datasheet and user manual will be available as soon as the product is offered for sale. More Images

Product Preview – AVR Graphical LCD Development Board

To bring graphic LCD to the reach of every embedded system engineer we have developed a complete hardware and software suite that can be used to develop rich graphical application easily and quickly. More information on graphical programming with GLCD and AVR ATmega series MCU is discussed in the following articles. Part I – Introduction to GLCD and Hardware Setup Part II – Downloading and Installing ProGFX! Part III – Explains Graphic Primitive Functions. Part IV – Font and Text Handling Functions. The aim is to create a common hardware and software platform to create and share graphical applications. The user can concentrate only on application level, leaving the low level details handled by ProGFX. The advantage is that the end application can be easily shared among the user of ProGFX boards. The applications are more usable because any ProGFX programmer can easily understand the application logic (due to clean uniform api) and modify the application to suit their need. eXtreme Electronics, India will work towards releasing many open source ProGFX applications for their users.
