ControlDM11A88

Simple DM11A88 8x8 led matrix library for ESP8266.

DM11A88

DM11A88 is a 8×8 square led matrix module which is based on a couple of 74hc595.

Library

This library can draw whatever you want on the display, but it needs to be constantly refreshed in the loop().

Full example (see writeM example):

#include <ControlDM11A88.h>

// Parameters: DI_PIN, CLK_PIN, LAT_PIN
ControlDM11A88 lc(D7, D8, D5, 1);

uint8_t i;
uint8_t led[] = {
    B10000010, B11000110, B10101010, B10010010,
    B10000010, B10000010, B10000010, B10000010,
};

void setup()
{
}

void loop()
{
    for (i=0; i<8; i++) {
        lc.setRow(0, i, led[i]);
    }
}

The library can help you to draw animations, too, see sprites and counter examples.

You can daisy chain multiple devices, see multipleDevices example.
