Adafruit PWM Servo Driver for MATLAB

Custom MATLAB Add-on for AdafruitPWMServoDriver for Arduino

To use, install Adafruit_PWM_Servo_Driver_Library in your Arduino path and run the following:

addpath('XXXX')
a = arduino('COM5','Uno','Libraries','Adafruit/PWMservoDriver')
shield = addon(a,'Adafruit/PWMservoDriver','I2CAddress','0x40')

To find the I2CAddess of your board:

i2cAddress = scanI2CBus(controller)

    <sub>i2cAddresses =

        1×2 string array

            '0x40' '0x53'</sub>

To find the port number of your board:

List of the available functions

All the functions of the Adafruit library are available in the addon with the same sintax as the original library.
For more detailed information, please visit the official library page: https://github.com/adafruit/Adafruit-PWM-Servo-Driver-Library

Function	Description	Return value
createServoDriver(byte driverNum, byte i2caddress)	Creates the Servo Driver class. driverNum used to reference the specific driver (for series I2C connection. Maximum 4 in Arduino Uno and 32 else). i2caddress used to reference the I2CAddress of the device ('0x40' - '0x80').	void
deleteServoDriver(byte driverNum)	Setups the I2C interface and hardware	void
begin(byte driverNum, unsigned int prescale)	Setups the I2C interface and hardware	void
reset(byte driverNum)	Sends a reset command to the PCA9685 chip over I2C	void
sleep(byte driverNum)	Puts board into sleep mode	void
wakeup(byte driverNum)	Wakes board from sleep	void
setExtClk(byte driverNum, unsigned int prescale)	Sets EXTCLK pin to use the external clock	void
setPWMFreq(byte driverNum, unsigned int pwmfreq)	Sets the PWM frequency for the entire chip, up to ~1.6 KHz	void
setOutputMode(byte driverNum, bool totempole)	Sets the output mode of the PCA9685 to either open drain or push pull / totempole. Warning: LEDs with integrated zener diodes should only be driven in open drain mode	void
getPWM(byte driverNum, unsigned int num)	Gets the PWM output of one of the PCA9685 pins num(0-15)	unsigned int
setPWM(byte driverNum, unsigned int num, unsigned int on, unsigned int off)	Sets the PWM output of one of the PCA9685 pins num(0-15) with on/off tick placement and properly handles a zero value as completely off and 4095 as completely on.	void
readPrescale(byte driverNum)	Reads set Prescale from PCA9685	unsigned int
writeMicroseconds(byte driverNum, unsigned int num, unsigned int microseconds)	Sets the PWM output of one of the PCA9685 pins based on the input microseconds, output is not precise num(0-15)	void
setOscillatorFrequency(byte driverNum, unsigned int oscFreq)	Setter for the internally tracked oscillator used for freq calculations	void
getOscillatorFrequency(byte driverNum)	Getter for the internally tracked oscillator used for freq calculations	unsigned int

The addon and the library have been tried both with the official Adafruit 12-Channel 16-bit PWM LED Driver - SPI Interface - TLC59711 and with generic PCA9685 PWM LED and Servo drivers as well.
