ok.. ive set up a test environment
made a simple sketch, this works fine
the exact same thing using gcode, also works.

#include
// PCA9685 I2C address is 0x40(64)
#define Addr 0x40
int mode = 0;
void setup()
{
// Initialise I2C communication as MASTER
Wire.begin();
// Start I2C Transmission
Wire.beginTransmission(Addr);
// Select MODE1 register
Wire.write(0x00);
// Response to LED all-call I2C address
Wire.write(0x01);
// Stop I2C Transmission
Wire.endTransmission();
delay(5);
// Start I2C Transmission
Wire.beginTransmission(Addr);
// Select ALL_LED_ON_L register
Wire.write(0x06);
// ALL_LED_ON lower byte
Wire.write(0x00);
