February 1, 2007[Ideas For Design] Create A PWM Signal Simply, Inexpensively
Sometimes you need to generate a pulse-width-modulation (PWM) signal for your circuit to simulate a certain behavior. The technique described here generates a simple programmable PWM signal for less than a dollar. The technique uses an MSP430F20xx 14-pin microcontroller (MCU). The devices in this series incorporate Timer_A2, which allows you to generate one PWM signal without CPU intervention. The timer houses two capture-compare registers, called CCR0 and CCR1, which...
