How Does The ED Ring 2 Click Board™ Work?
The LED Ring 2 Click Board™ is based on the LP5862, a high-performance LED matrix driver from Texas Instruments. The LP5862 integrates 18 constant current sinks for driving 18 LEDs. A standard yellow LED is used as a light source, the SML-LX0402SYC-TR, with a peak wavelength of 590nm. With the help of two additional LP5862 drivers, it is realized, as shown on this board, a LED ring of 54 yellow LEDs arranged in a circular pattern. This Click board™ can significantly improve user experience in various animation and indication application areas like smart home, gaming equipment, and other human-machine interaction applications.
The LED Ring 2 Click Board™ communicates with an MCU using the standard I2C 2-Wire interface to read data and configure settings, supporting Fast-Plus mode with a frequency of up to 1MHz. The LP5862 also supports the register-configurable PWM dimming method for efficiently adjusting LED light brightness. For PWM dimming, the integrated 8-bit or 16-bit configurable, >20kHz PWM generators for each LED enable smooth, vivid animation effects without audible noise. Each LED can also be mapped into an 8-bit group PWM to achieve group control with minimum data traffic. The VSY pin of the mikroBUS™ socket serves as a synchronization signal.
The LP5862 also implements full addressable SRAM, supporting entire SRAM data refresh and partial SRAM data update on demand to minimize the data traffic. Besides, the LP5862 implements the ghost cancellation circuit to eliminate upside and downside ghosting.
The LED Ring 2 Click Board™ can operate with either 3.3V or 5V logic voltage levels selected via the VCC SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. In addition, it is possible to select the LED supply voltage between either 3.3V or 5V voltage level set via the VLED SEL jumper. However, the Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.
