file PCA9685: func: void PCA9685::setPWM(uint8_t led, int on_value, int off_value) {
i2c->write_byte(LED0_ON_L + LED_MULTIPLYER * (led - 1), on_value & 0xFF);
i2c->write_byte(LED0_ON_H + LED_MULTIPLYER * (led - 1), on_value >> 8);
i2c->write_byte(LED0_OFF_L + LED_MULTIPLYER * (led - 1), off_value & 0xFF);
i2c->write_byte(LED0_OFF_H + LED_MULTIPLYER * (led - 1), off_value >> 8);
}
if (led==0) address = LED0_ON_L - LED_MULTIPLYER
its not led0 address

Could you conntect the A-pins straight to GND and the OE-pin straight to 5V(HIGH) if you use the libary and what is the default i2c address, because I haven't find the default address in the documentation.

When I want to initalize the Libary on my raspi i get this error:
error: expected identifier before numeric constant
PCA9685 dac(1,0x60);

Just cloned this repo and it doesn't build. I noticed that it was trying to include your "I2C.h" file in the PCA9685.h file so I cloned that and tried two things:

1. Move the I2C source and header to the PCA9685 source folder and attempted to build which didn't work.
2. Build just the I2C project which gave the error:

pi@raspberrypi2:~/MasterControl/PiLight/I2C/src$ make

<builtin>: recipe for target 'I2C.o' failed
make: *** [I2C.o] Error 1

How was this meant to be used seeing as how nothing compiles?

It cannot find I2C.h when making, is there any way to build it? Cannot build neither, I2C on the other repo..

On the datasheet the min and max is 40hz to 1500hz not 40Mhz to 1500Mhz.

friend,
do you have the dll of this code so I can use it in C #? I do not handle anything in C ++.
Thankful.
