  • y - y coordinate, from 0 to 8
  • color - color of the LED (or off)

Examples

use ht16k33::i2c_mock::I2cMock;
use ht16k33::{HT16K33, Display};
use adafruit_led_backpack::{BicolorMatrix8x8, Color};

// Create an I2C device.
let mut i2c = I2cMock::new();

// Create a HT16K33 instance, the implementation of BicolorMatrix8x8 is in scope.
let mut ht16k33 = HT16K33::new(i2c, 0x70);
ht16k33.initialize();
ht16k33.update_bicolor_led(4, 4, Color::Red);
ht16k33.set_display(Display::ON);
ht16k33.write_display_buffer();
