The The MikroElektronika's 8800 Retro Click is a compact add on board that simplifies the control of multiple LEDs. This board features the AS1115, compact LED driver for 8x8 display screen programmed via a compatible 2-wire I2C interface from ASM-AG. The AS1115 includes an integrated BCD code B or HEX decoder, multiplex scan circuitry, segment and display drivers, and 64-bit memory. Internal memory stores the shift register settings, eliminating the need for continuous device reprogramming. All outputs of the AS1115 can be configured for key read back, where key switch status is obtained by polling for up to 64 keys, while 16 keys can be used to trigger an interrupt. This Click board is suitable for seven-segment or dot matrix user-interface displays and other white goods or personal electronic applications.
