PIC16F684的低成本双向直流有刷电机控制

资料介绍
This application note discusses how to use the
Enhanced, Capture, Compare, PWM (ECCP) on the
PIC16F684 for bidirectional, brushed DC (BDC) motor
control. Low-cost brushed DC motor control can be
used in applications such as intelligent toys, small
appliances and power tools. The PIC16F684 takes
Microchip's Mid-Range Family of products to the next
level with its new ECCP peripheral. The ECCP
peripheral builds on the technology of the CCP module
with added features such as four PWM channels for
easy bidirectional motor control through the hardware.
This application note focuses on using the ECCP in
PWM mode using the full-bridge configuration. Using
the ECCP allows easy interfacing to a full-bridge
configuration for bidirectional BDC motor control.
This application note will discuss the following:
• Calculating ECCP PWM Parameters
• Initializing the ECCP in full-bridge PWM mode
• Bidirectional BDC Motor Control
• Sensorless Motor Control Feedback
• Example Application

Microchip Technology Inc. PARAMETERS
When working with the ECCP in PWM mode, the PWM
INTRODUCTION frequency, duty cycle and resolution, there are three
useful pieces of information to be calculated.
