This project is very similar to Project 5, only in this project, we are using the Enhanced
Capture Compare PWM (ECCP) module in the PIC16F690 (see note). In PWM mode,
the ECCP module has four outputs for directly driving an H-bridge circuit. This makes
implementing bidirectional speed control of a Brushed DC motor a simple task.
Objectives
1. Configure the ECCP module for Full-Bridge mode.
2. Change motor directions.

Jumper Configuration
• P1A (J6) to P1 (J1)
• P1B (J6) to N1 (J1)
• P1C (J6) to P2 (J1)
• P1D (J5) to N2 (J1)
• AN2 (J5) to POT1 (J4)
• RA5 (J6) to SW2 (J4)
• Make sure there are no shunts (two pin jumpers) on J2.
• Attach the Brushed DC motor leads to DRIVE1 (P9) and DRIVE2 (P10).
• Connect the right and center pins of JP8 using a shunt.
