I'm afraid I'm confused again. According to the write-up on the Wave Shield, it uses pins 13, 12, 11 for one purpose, pins 10, 2, 3, 4, 5 for other purposes, and 9 for the timer. That leaves exactly pins 6,7,8 and the analog pins (digital i/o pins). Which means only 6,7,8 are available for PWM using SoftPWM. Can the analog pins be used for PWM?. If so, how? If they're digital i/o.
