The SLO2016 module is paired up with the MCP23017 I2C port expander for easier use and minimal command lines.
Data is sent via the I2C expander. D0-D6 are used to select ASCII character from internal memory. A0 and A1 bits are used to select which place takes which character (1,2,3,4).
Detailed instructions are provided in the modules datasheet. The PWM pin is intended for blanking the display, and it can also be used for dimming the display.
The CLR function clears the ASCII characters RAM.
SLO2016 is a 4-Digit 5x7 Dot Matrix Alphanumeric intelligent display, with many built-in functions that will save your time. The integrated circuit contains memory, a 128 ASCII ROM decoder, multiplexing circuitry and drivers.
The character set consists of 128 special ASCII characters for English, German, Italian, Swedish, Danish, and Norwegian. So, you don't need to build a character set yourself.
You also have direct access to each digit independently and asynchronously.
