References and Notes

The biggest struggle with this project so far has been finding the gems of useful information in the large quantities of documentation out there, so I'm pasting a list of things that turned out to be useful here.

Switchmode Power Stage Designer Useful calculator for comparing hardware designs

Poentially useful device tree configuration example for Bacon Cape Yes! The RGB LED example turned out to be the only way to set PWM period correctly with two outputs enabled. The interface that is enabled and accessible through /sys/class/pwm doesn't initialize the pwm period to a stupid default value. It still can only be set once, but that's one more chance than pwm_test gives you.

Might need to look at this to get ehrpwm on kernels <3.8 Nope. Ain't gonna try to run <3.8 on a beaglebone black

United States Patent US6836414 I've been struggling to generate the waveforms in Fig. 2a, but if Fig. 2b works too, i should just use that because i can easily do that through /sys/class/pwm
