led_panel.show_image(list, mode = 0)

Set the display content as image parameter mode, parameters：

• list changeable parameter list, each value ranges is 0 ~ 8， the first parameter means the first light color, the second parameter means the second light color, and so on. And color parameters are as below: black(0x00), red(0x01), orange(0x02), yellow(0x03), green(0x04), cray(0x05), blue(0x06), purple(0x07) and while(0x08).
• mode contents displaying mode, the parameter range is 0 ~ 3

0：means emerging mode, setting image will display directly.

1：means erase mode, original image disappear gradually and new setting image will display gradually and vertically.

2：means left moving mode, original image moves to the left and disappear gradually and new setting image will move to the left until display the whole image.

3：means right moving mode, original image moves to the right and disappear gradually and new setting image will move to the right until display the whole image.

led_panel.set_animation(frame_index, list)

Set the animation content on the panel, parameters：

• frame_index index of the animation frame, the parameter range is 0 ~ 3; 0 mean the first frame, 1 means the second, and so on.
• list changeable parameter list, each value ranges is 0 ~ 8, the first parameter means the first light color, the second parameter means the second light color, and so on; And color parameters are as below: black(0x00), red(0x01), orange(0x02), yellow(0x03), green(0x04), cray(0x05), blue(0x06), purple(0x07) and while(0x08).

led_panel.show_animation(frame_speed, mode)

Show the animation frame setting by set_animation, parameters：

• frame_speed switch speed of the animation frame content, the parameter range is 0 ~ 2

0：means slow speed that the animation frame rolls every one second

1：means normal speed that the animation frame rolls every half second

2：means fast speed that the animation frame rolls every 0.2 second.

• mode frame change mode, the parameter range is 0 ~ 3

  0：means emerging mode, setting image will display directly.

  1：means erase mode, original image disappear gradually and new setting image will display gradually and vertically.

  2：means left moving mode, original image moves to the left and disappear gradually and new setting image will move to the left until display the whole image.

  3：means right moving mode, original image moves to the right and disappear gradually and new setting image will move to the right until display the whole image.

led_panel.show_string(red_value, green_value, blue_value, list)

Display the string as the setting color, parameters：

• red_value Set LED red value, the parameter range is 0 ~ 255, 0 means no red color, 255 means the brightest red color.
• green_value Set LED green value, the parameter range is 0 ~ 255, 0 means no green color, 255 means the brightest green color.
• blue_value Set LED blue value, the parameter range is 0 ~ 255, 0 means no blue color, 255 means the brightest blue color.
• list changeable parameter list, the first character, the second character, the third character…
