J2B: Universal MMI Module using ARM Cortex-M3

Let’s stop reinventing the wheel!

Published in issue 9/2011 on page 36

When we take a closer look at circuits using a microcontroller, it can be seen that in 75 % of cases the basic circuit is virtually identical: a microcontroller, an LCD display, and a few push-buttons. This observation is nothing new, and Elektor in particular has already suggested several solutions. This article presents yet another way of going about it, a little bit more universal, which allows the use of several types of LCD and a variable number of buttons. And thanks to its up-to-the-minute LPC1343 ARM Cortex-M3 processor, this board is extra powerful and amazingly easy to use.
