특징
- 7-SEG 2 Click is a compact add-on board that represents an easy solution for adding a numeric or hexadecimal display to your application. This board features the LDT-M2804RI, a three-digit seven-segment display from Lumex. The display has a 0.28" height, red LED segments, gray faces, and white diffused segments. All three digits come with a following dot point that can be used as a decimal point in displaying the number values. This Click board™ makes the perfect solution for the development of many applications requiring a visible display or others that display numerical/textual information.

HOW DOES IT WORK?
7-SEG 2 Click is based on the LDT-M2804RI, a three-digit seven-segment display from Lumex. The red LED segments have a common anode, a 635nm wavelength, and a luminous intensity of 5000mcd. The LED1202, a 12-channel low-quiescent current LED driver from STMicroelectronics, drives the display. The output current can be adjusted separately for each channel by a 12-bit digital dimming control. A slow turn-on and turn-off time improves the system's low noise generation performance; moreover, the phase shifting function helps to reduce the inrush current. Eight patterns can be stored in the driver for automatic sequencing without MCU intervention.
7-SEG 2 Click uses a standard 2-wire I2C communication from the LED driver to allow the host MCU to control the seven-segment display. The I2C interface supports clock frequencies of up to 400kHz. The I2C address can be selected over the ADDR SEL jumpers. The interrupt INT pin will notify the host MCU when an interrupt event occurs. It can be an open LED detection, overtemperature protection, the pattern fault and status interrupt, the start of frame, and more.
This 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. Also, this 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.
