LibDriver TM1637

MISRA API License

TM1637 is a kind of LED (light-emitting diode display) drive control special circuit with keyboard scan interface and it's internally integrated with MCU digital interface, data latch, LED high pressure drive and keyboard scan. This product is in DIP20/SOP20 package type with excellent performance and high quality, which is mainly applicable to the display drive of induction cooker, micro-wave oven and small household electrical appliance.

LibDriver TM1637 is the full function driver of TM1637 launched by LibDriver. LibDriver TM1637 provides digital tube display, keypad scanning and other functions. LibDriver is MISRA compliant.

Install

Reference /interface IIC platform independent template and finish your platform IIC driver.

Add the /src directory, the interface driver for your platform, and your own drivers to your project, if you want to use the default example drivers, add the /example directory to your project.

Usage

You can refer to the examples in the /example directory to complete your own driver. If you want to use the default programming examples, here's how to use them.

example basic

#include "driver_tm1637_basic.h"

uint8_t res;
uint8_t seg;
uint8_t k;
uint8_t number[] = {TM1637_NUMBER_0, TM1637_NUMBER_1, TM1637_NUMBER_2,
                    TM1637_NUMBER_3, TM1637_NUMBER_4, TM1637_NUMBER_5,
                    TM1637_NUMBER_6, TM1637_NUMBER_7, TM1637_NUMBER_8, TM1637_NUMBER_9};

/* init */
res = tm1637_basic_init();
if (res != 0)
{
    return 1;
}

...
    
/* write */
res = tm1637_basic_write(0, &number[0], 6);
if (res != 0)
{
    (void)tm1637_basic_deinit();
    
    return 1;
}

...
    
/* read */
res = tm1637_basic_read(&seg, &k);
if (res != 0)
{
    (void)tm1637_basic_deinit();
    
    return 1;
}

/* output */
tm1637_interface_debug_print("tm1637: seg: 0x%02X.\n", seg);
tm1637_interface_debug_print("tm1637: k: 0x%02X.\n", k);

...
    
/* on */
res = tm1637_basic_display_on();
if (res != 0)
{
    (void)tm1637_basic_deinit();
    
    return 1;
}

...
    
/* off */
res = tm1637_basic_display_off();
if (res != 0)
{
    (void)tm1637_basic_deinit();
    
    return 1;
}

...
    
/* deinit */
(void)tm1637_basic_deinit();

return 0;
