## LibDriver BUTTON [![MISRA](https://img.shields.io/badge/misra-compliant-brightgreen.svg)](/misra/README.md) [![API](https://img.shields.io/badge/api-reference-blue.svg)](https://www.libdriver.com/docs/button/index.html) [![License](https://img.shields.io/badge/license-MIT-brightgreen.svg)](/LICENSE) A push-button or simply button is a simple switch mechanism to control some aspect of a machine or a process. Buttons are typically made out of hard material, usually plastic or metal. The surface is usually flat or shaped to accommodate the human finger or hand, so as to be easily depressed or pushed. Buttons are most often biased switches, although many un-biased buttons (due to their physical nature) still require a spring to return to their un-pushed state. LibDriver BUTTON is a full-featured driver for BUTTON, launched by LibDriver. It provides press, release, single click, double click , triple click, repeat click, short press, long press and additional features. LibDriver is MISRA compliant. LibDriver BUTTON supports single button detection and can be run in a more efficient method, if you need multi-button or matrix-button detection, please refer to [https://gitee.com/libdriver/multi_button](https://gitee.com/libdriver/multi_button). ### Table of Contents - [Instruction](#Instruction) - [Install](#Install) - [Usage](#Usage) - [example basic](#example-basic) - [Document](#Document) - [Contributing](#Contributing) - [License](#License) - [Contact Us](#Contact-Us) ### Instruction /src includes LibDriver BUTTON source files. /interface includes LibDriver BUTTON GPIO platform independent template. /test includes LibDriver BUTTON driver test code and this code can test the chip necessary function simply. /example includes LibDriver BUTTON sample code. /doc includes LibDriver BUTTON offline document. /datasheet includes BUTTON datasheet. /project includes the common Linux and MCU development board sample code. All projects use the shell script to debug the driver and the detail instruction can be found in each project's README.md. /misra includes the LibDriver MISRA code scanning results. ### Install Reference /interface GPIO platform independent template and finish your platform GPIO 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 ```C #include "driver_button_basic.h" uint8_t res; uint8_t (*g_gpio_irq)(uint8_t) = NULL; uint8_t (*g_period_irq)(void) = NULL; static void a_receive_callback(button_t *data) { switch (data->status) { case BUTTON_STATUS_PRESS : { break; } case BUTTON_STATUS_RELEASE : { break; } case BUTTON_STATUS_SINGLE_CLICK : { button_interface_debug_print("button: irq single click.\n"); break; } case BUTTON_STATUS_DOUBLE_CLICK : { button_interface_debug_print("button: irq double click.\n"); break; } case BUTTON_STATUS_TRIPLE_CLICK : { button_interface_debug_print("button: irq triple click.\n"); break; } case BUTTON_STATUS_REPEAT_CLICK : { button_interface_debug_print("button: irq repeat click with %d times.\n", data->times); break; } case BUTTON_STATUS_SHORT_PRESS_START : { button_interface_debug_print("button: irq short press start.\n"); break; } case BUTTON_STATUS_SHORT_PRESS_END : { button_interface_debug_print("button: irq short press end.\n"); break; } case BUTTON_STATUS_LONG_PRESS_START : { button_interface_debug_print("button: irq long press start.\n"); break; } case BUTTON_STATUS_LONG_PRESS_HOLD : { button_interface_debug_print("button: irq long press hold.\n"); break; } case BUTTON_STATUS_LONG_PRESS_END : { button_interface_debug_print("button: irq long press end.\n"); break; } default : { button_interface_debug_print("button: irq unknown status.\n"); break; } } } /* gpio init */ res = gpio_interrupt_init(); if (res != 0) { return 1; } /* set the irq */ g_gpio_irq = button_basic_irq_handler; g_period_irq = button_basic_period_handler; /* basic init */ res = button_basic_init(a_receive_callback); if (res != 0) { (void)gpio_interrupt_deinit(); g_gpio_irq = NULL; g_period_irq = NULL; } ... while (1) { ... } ... /* basic deinit */ (void)button_basic_deinit(); /* gpio deinit */ (void)gpio_interrupt_deinit(); g_gpio_irq = NULL; g_period_irq = NULL; return 0; ``` ### Document Online documents: [https://www.libdriver.com/docs/button/index.html](https://www.libdriver.com/docs/button/index.html).
