You cannot imagine to use microcontroller without using any of its i/o pins. Finally its all about : taking input , processing it and generating output ! Thus i/o registers and their correct settings is indispensable part while learning to program any uC.
We will learn how to use AVR ports and actually ‘code’ for writing/reading data to/from port pins. It is slightly confusing for beginners, however once you understand it, you will certainly appreciate the way it is designed.
Maxim Integrated Products (NASDAQ: MXIM) introduces the MAX44251 a 20V, ultra-precise, low-noise dual op amp that extends system uptime, decreases system maintenance and maximizes sensor performance. Proprietary autozero technology enables continuous self-calibration which, in turn, ensures system accuracy over time, temperature, and power-supply variations. The precision (< 6µV offset) over the wide 2.7V to 20V operating range is unmatched by the competition.
Maxim Integrated Products (NASDAQ: MXIM) introduces the MAX2982, the first broadband, HomePlug® 1.0-compliant, powerline communications transceiver for harsh industrial environments. The MAX2982 is highly integrated and offers significant design flexibility. An enhanced "Robust" mode provides a receiver that operates at -1dB signal-to-noise (SNR) to ensure reliable communications in the presence of noise. The device operates from -40°C to +105°C and is qualified under AEC-Q100-Rev-G for harsh applications.
