The use of timer 1, timer 2 and the capture/compare/PWM (CCP) module is detailed, followed by timing, counting and pulse width modulation (PWM) experiments. These experiments include producing a single time interval output, free running pulse output, event counting, time measurement, frequency measurement and PWM. Some of these techniques are illustrated further by experiments which show how to design and build simple digital pulse and frequency generators and time interval and frequency measurement instruments.
The book also explains how to establish serial communication between a PIC chip and a PC via a RS-232 conversion circuit and a terminal program. These techniques are used in a digital voltmeter/data logger experiment for uploading data to a PC for display plus graphing using a spreadsheet program. PIC'n Techniques illustrates techniques used in designing and building intermediate level microcontroller-based instrumentation and systems.
