Hello,
I'm using an Arduino UNO for programming the TLC59116 and I'm able to configure the component and read the configuration but I can't see any efect happening on the LEDs. Here is the configuration I have:
START

I'm reading it using a USBee Sx and this is what it decode it from SDA.
This is the code I'm executing:
// Transmit to the TLC59116
Wire.beginTransmission(ADDRESS);
// Send the control register. All registers will be written to, starting at register 0
Wire.write(byte(AUTO_INCREMENT_ALL_REGISTERS));
// Set MODE1: no sub-addressing
Wire.write(byte(0));
// Set MODE2: dimming
Wire.write(byte(0x20));
// Set individual brightness control to maximum
for (int i=0; i< 16; i++)
Wire.write(byte(0xff)); //0XFF
// Set GRPPWM: Full brightness
Wire.write(byte(0xff)); //0XFF
// Set GRPFREQ: Not blinking, must be 0
Wire.write(byte(0));
// Set LEDs off for now
for (int i=0; i< 4; i++)
Wire.write(byte(0x10));
// Set the I2C all-call and sub addresses (if needed)
Wire.endTransmission();
delay(100);

Pascal
