The usual method of bringing analog inputs into a microprocessor is to use an analog-to-digital converter (ADC). Here are some tips for selecting such a part and calibrating it to fit your needs.
Microchip Technology Inc., a leading provider of microcontroller, analog and Flash-IP solutions, today announced the upgrade of its formerly 60 MIPS enhanced-core dsPIC33E Digital Signal Controllers (DSCs) and PIC24E microcontrollers (MCUs) to 70 MIPS performance.
All microcontroller developers for debugging and device control use serial communication via a computer (or other device). The most commonly used serial communication is RS232. Ten years ago, every computer was equipped with a serial port, but today it is uncommon on PC platforms and almost non-existent in laptops.
