Finish assigning BeagleBone black pins. #280

Closed AhmedSamara closed 9 years ago

AhmedSamara commented 9 years ago

Still to be assigned:

Signal type Suggested pin notes
Rubix cube gripper motor dir: GPIO P9_30 (gpio3[16]) (k-112)
Rubix cube gripper power: PWM P9_29 (EHRPWM0B)
Simon says servo: PWM P9_21 (EHRPWM0A)
Etch-a-sketch stepper (left) PWM P9_14 (EHRPWM1A) stepper motors previously required 4 GPIOS, but the new design by Josh lets us use one PWM.
Etch-a-sketch stepper (right) PWM P9_16 (EHRPWM1B) (directly next to the other etch-sketch pwm. Easier wiring

All of these assignments were pretty much picked arbitrarily, but unless anyone (Particularly @jasteve4 ) has any assignments or designs/code with other assumptions or a reason to use ECAP PWM, over EHRPWM I'm going to go ahead and use these.

This has to change, the rubix gripper actually requires two GPIOs for controlling direction, and doesn't really need a PWM.

This issue can be closed, this years bot will not need gripper.
