PCA9685 Utility

PCA9685 servo driver utility for the Raspberry Pi, using wiringPi

Prerequisite

Please install the pca9685 driver from @Reinbert. Also, this utility is based on WiringPi, so, you'll need make sure you have WiringPi installed before you can succesfully compile this library.

https://github.com/Reinbert/pca9685.git

Install

To compile this library, navigate into the src folder and use the make utility to compile and install the library.

$ make && make install

Usage

$ pca9685
usage: pwm [-a 00-FF] [-c cap] [-p 0-15] [-f freq] [-m freq] [-x freq] [-e]
a = hexadecimal i2c address of the PCA9685 ($ gpio i2cd); default 0x40
p = PCA9685 pin number (0-15)
e = use even split pulse, default is trigger pulse which is for servos
c = frequency cap (40-1526).  The default is 50, which is for servos
m = min freq
x = max freq
f = frequency 0-100
Mode:   f     - set frequency and exit. (override m & x)        m & x - run test over range.

Example

Examples using the utility:

$ pca9685 -p 0 -f 230
$ pca9685 -p 1 -f 325

$ pca9685 -p 0 -f 163
$ pca9685 -p 1 -f 397
