Four Digit Display Suli

4 digit display module is usually a 12 pin module. In this Grove gadget, we utilize a TM1637 to scale down the controlling pins into 2 Grove pins. It only takes 2 digital pins of Arduino or Seeeduino to control the content, even the luminance of this display. For projects that require of alpha-numeric display, this can be a nice choice.For more information visit our wiki

Grove - 4-Digit Display

Features

  • 4 digit red alpha-numeric display
  • Grove compatible
  • 8 adjustable luminance levels

Application Ideas

  • Time display
  • Stopwatch
  • Sensors’ input display

#Usage

Initialize

This function use to initialize the device at the very beginning. You can set the pin to used here.

void four_digit_init(PIN_T data, PIN_T clk);

Set Brightness

This function can set the brightness of the device.

void four_digit_set_brightness(enum brightness_t b);

And the enum of brightness was defined in Four_Digit_Display.h

enum brightness_t
{
    BRIGHT_DARKEST = 0,
    BRIGHT_TYPICAL = 2,
    BRIGHTEST      = 7
};

Set Point

You can find a colon in the middle of the display. This function can turn on and off this colon.

void four_digit_set_point(bool disp_point);		// 1-on, 0-off

Display a Bit

You can find 4Bit in the display.

void four_digit_display(uint8 BitAddr,int8 DispData);

BitAddr: 0-3, from right to left DispData: number to display, should be between 0-9

Clear

Clear all the display.

void four_digit_clear();

----- **Note:**

This is a Suli-Compatible Library, You Should Download Suli for your platform, please refer to https://github.com/Seeed-Studio/Suli

If you can't find Suli for your platform, please contract us, If you can port it yourself and pull request to us, We'll be appreciated.

For Arduino:

Just like you use the other Library, What's different is you should download Suli for Arduino First, remember that just put Suli for Arduino to your Arduino libraries folder.

For non-Arduino Platform:

For a non-Arduino platform, what you need is xxx.h and xxx.cpp(you can change it to xxx.c while your compiler can't support c++), the other files like xxx_Arduino.h and examples is for Arduino, you can just delete them.
