AN899, Brushless DC Motor Control Using …
2004 Microchip Technology 1AN899 INTRODUCTIONThe PIC18F2331/2431/4331/4431 family of micro-controllers have peripherals that are suitable for motorcontrol applications. These peripherals and some oftheir primary features are: Power Control PWM (PCPWM)- Up to 8 output channels- Up to 14-bit PWM resolution- Center-aligned or edge-aligned operation- Hardware shutdown by Fault pins, etc. Quadrature Encoder Interface (QEI)- QEA, QEB and Index interface- High and low resolution position measurement- Velocity Measurement mode Using Timer5- Interrupt on detection of direction change Input Capture (IC)- Pulse width measurement- Different modes to capture timer on edge- Capture on every input pin edge- Interrupt on every capture event High-Speed Analog-to-Digital Converter (ADC)- Two sample and hold circuits- Single/Multichannel sel
