Description:

16-bit i2c led driver.

PCA9552, 16-bit I2C LED driver

The PCA9552 LED blinker blinks LEDs in I2C-bus and SMBus applications where it is necessary to limit bus traffic or free up the I2C-bus controller's (MCU, MPU, DSP, chip set, etc.) timer.

The uniqueness of this device is the internal oscillator with two programmable blink rates.

To blink LEDs using

PCA9552 Features

* 16 LED drivers (on, off, flashing at a programmable rate)

* 2 selectable, fully programmable blink rates (frequency and duty cycle) between 0.172 Hz and 44 Hz (5.82 seconds and 0.023 seconds)

* Input/outputs not used as LED drivers can be used as regular GPIOs

* Int
