How Does The LED Driver 19 Click Board™ Work?
The LED Driver 19 Click Board™ is based on the LED1202, a 12-channel low quiescent current LED driver from STMicroelectronics. Its internal non-volatile memory can store up to 8 different patterns, each with a particular output configuration, thus enabling automatic sequencing without MCU intervention. Each channel has an output PWM dimming frequency of 220Hz in a 12-bit resolution. Analog dimming range is from 1 up to 20mA, in 256 steps per channel, and common to all patterns. In addition, using one of the PWM or analog modes, you can use both of them to achieve full control of LED brightness. This LED driver also features a built-in open LED detection and thermal shutdown function that turns OFF all output drivers during an over-temperature condition.
The LED Driver 19 Click Board™ uses a standard I2C 2-Wire interface to communicate with the host MCU. The I2C address can be selected via two ADDR SEL jumpers, where 0 is selected by default on both. The LED1202 driver can generate an interrupt on the INT pin if a fault or condition occurs; by that, it means an open LED, overtemperature, pattern end, and frame start. The INT pin informs the system about those statuses with active LOW.
The LED Driver 19 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. 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.
