Hello
I hope this is the correct category for asking about the LTC3220 led driver. I have designed a circuit with LTC3220 and I try to write the firmware communicating with it. I have tried the 0x1C address as the datasheet says but I keep getting NACK.
I2C pullups are 4.7k and rst signal is hardwired to LTC3220 Vin, which is 3.3V. I turn on the LTC3220 with the use of a linear voltage regulator. I have measured CPO output and is outputting correctly the 3.3V. Charge pump pins also work correctly.
Can you please guide me into solving my problem.
Thank you in advance
