The Micro Electro Mechanical Systems technology (aka MEMS) allows to integrate on the same silicon substrate both electronic circuits and optical-mechanical devices, adopting semiconductor fabrication technologies similar to those used to make integrated circuits.

I never handled an iPod touch until a few days a ago. But a friend of mine received as birthday present the media player iPod Touch and so I had the chance to analyze it. What can I say? It's very thin and surprising. Once you start using it, you can not leave it! The iPod touch has a reduced size: height 110mm, width 61.8mm and only 8 mm thick. Weighs only 120 grams. The 3.5 inches widescreen format display has a resolution of 480 x 320 pixels at 163 ppi. The iPod touch provides Wi-Fi wireless connectivity (802.11b/g) - the only iPod to have it.

I first learned of the STM32 Primer at a technical seminar presented by STMicroelectronics. The STM32 Primer is designed to provide a complete toolset for STM32 that is fun and easy to use. Give it a try and learn about the features of the STM32 and the powerful ARM Cortex™-M3 core.
