The LED Driver 9 Click Board™ as its foundation uses the TLC59116, an I2C bus controlled 16-channel LED driver optimized for red/green/blue/amber (RGBA) colour mixing and backlight application from Texas Instruments. It operates within a VCC supply voltage range where its outputs are 17V tolerant. Each LED output, 16 LED drivers presented on two 2x5 male headers, with a maximum output current of 120mA per channel, is programmable at OFF and ON state, has programmable individual LED brightness with group dimming and blinking.
Each LED output has its individual PWM controller, which allows each LED to be set at a specific brightness value. An additional 8-bit resolution (256 steps) group PWM controller has a fixed frequency of 190Hz and an adjustable frequency between 24Hz to once every 10.73 seconds, with an adjustable duty cycle from 0% to 99.6%.
The LED Driver 9 Click Board™ communicates with MCU using standard I2C 2-Wire interface, with a clock frequency up to 100kHz in the Standard, 400kHz in the Fast, and 1MHz in the Fast Mode Plus. The Software Reset feature allows the MCU to perform a reset of the TLC59116 through the I2C bus, identical to the Power-On Reset (POR) that initializes the registers to their default state, causing the outputs to be set high, which means that the LEDs are OFF. This allows an easy and quick way to reconfigure all device registers to the same condition. Also, this Click board™ has a Reset pin routed to the RST pin on the mikroBUS™ socket, which holds registers in their default states until the RST pin is set to a logic high state.
At the top of this Click board™, there is also a terminal labelled Rext used to connect an external resistor to set the LED current. The TLC59116 scales up the reference current set by the external resistor to sink the output current at each output port.
The LED Driver 9 Click Board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before use with MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used, as a reference, for further development.

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on the mikroE Github account.
Other mikroE Libraries used in the example:
Depending on the development board you are using, you may need a USB UART click, USB UART 2 click or RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.
The LED Driver 9 Click Board™is supported with mikroSDK - MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
