Mikroe 8800 Retro Click

Mikroe 8800 Retro Click features the ams AS1115 compact LED driver for 8x8 display screen programmed via a compatible 2-wire I²C interface. The AS1115 includes an integrated BCD code-B/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-readback, where key-switch status is obtained by polling for up to 64 keys, while 16 keys can be used to trigger an interrupt.
