특징

  • HOW DOES IT WORK?

    AlphaNum G 2 Click is based on the LTP-3862, a dual-digit 16-segment alphanumeric green display from Lite-ON. It has a 75mW of power disipation per segment. The TLC5947, a 24-channel 12-bit PWM LED driver from Texas Instruments, drives all these LED segments. It is a constant current sink LED driver with adjustable 4096 pulse width modulation (PWM) on each channel individually. The PWM control is repeated automatically with the programmed grayscale data. An external resistor sets the constant current to around 10mA. The LED driver features thermal shutdown, auto display repeat, noise reduction, and more.

    AlphaNum G 2 Click uses a standard 4-Wire SPI serial interface to communicate with the host MCU, supporting a clock frequency of up to 30MHz. A Blank BLK pin can turn all constant current outputs to OFF while initializing the grayscale PWM timing. This can be achieved by writing the High logic state on the Blank pin. You can also turn off every display separately, no matter the LED driver IC, over the CA1 and CA2 pins. Those pins control the common anode pins of the displays.

    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.
