Okay, so I've updated my N+2 to 4.2.2.2 and I am transitioning my PWM controls off the on board (since I need 15) to the AdaFruit 16 channel 12 bit PWM controller. (http://www.adafruit.com/products/815). I've got it hooked up as such:
Netduino + 2 SC Pin -> SCL Pin (Pullup off 3.3v with a 2.2k)
Netduino + 2 SD Pin -> SDA Pin (Pullup off 3.3v with a 2.2k)
3.3v -> VCC
GND -> GND
Here is how it is set up:
I am using the 'driver' class from http://forums.netdui...wms/#entry42442
and executing the following:
Adafruit_PWMServoDriver Light1 = new Adafruit_PWMServoDriver();Light1.setPWMFreq(100);Light1.setPWM(4, 0, 200);
I don't have a scope, so I'm sort of flying blind but with the PWM of channel 4 hooked up to a channel that works if I control it directly from the N+2 nothing changes when I set it as displayed, it's at 100%.
I'm a 100% newbie on i2c stuff, BrandonW6's driver doesn't mean too much to me, where can I start troubleshooting?
Thanks!
