上一篇经验记录了如何跑一个DEMO程序。本文分享如何在WICED中增加自己的应用程序。
一、目标
实现的目标是：
1、在APPS目录下增加自己的应用程序路径
2、基于SCAN程序扩展，每按一次SW2，扫描一次而不是像DEMO程序里那样不停的扫描。
二、动手操作啦
首先在apps下新建文件夹，如下图所示：
将demo程序中的scan.c和scan.mk复制到新建目录下，重要的来啦：将scan.mk重命名为icylinker.mk：
然后将编译TARGET整理一下，多余的去掉，留下自己需要的：
不解释，编译一下运行，效果和demo程序一样，下面继续开始写代码，完成我们自己定的功能。
三、编程开始啦
要用到按键SW2，是PA1，也可以看platform.h：
流程大概如下：
创建一个线程用于按键检测——》按键按下发送信号量——》主线程里等待信号量——》执行扫描；
上代码：
#include <stdlib.h>#include "wiced.h"#include "platform.h"/****************************************************** * Macros ******************************************************//****************************************************** * Constants ******************************************************/#define DELAY_BETWEEN_SCANS (5000)/****************************************************** * Enumerations ******************************************************//****************************************************** * Type Definitions ******************************************************//****************************************************** * Structures ******************************************************//****************************************************** * Static Function Declarations ******************************************************/wiced_result_t scan_result_handler( wiced_scan_handler_result_t* malloced_scan_result );/****************************************************** * Variable Definitions ******************************************************/static int record_count;static wiced_time_t scan_start_time;wiced_semaphore_t stIcylinkerButtonSem;wiced_thread_t stIcylinkerButtonThread;#define BUTTON_PRIORITY (9)#define BUTTON_STACK_SIZE (1*1024)void vButtonFunction(void *);/****************************************************** * Function Definitions ******************************************************/void application_start( ){ wiced_init( ); wiced_gpio_init(WICED_GPIO_2, INPUT_PULL_UP); /* * wiced_result_t wiced_gpio_init( wiced_gpio_t gpio, wiced_gpio_config_t configuration ); * wiced_result_t wiced_rtos_create_thread( wiced_thread_t* thread, uint8_t priority, const char* name, wiced_thread_function_t function, uint32_t stack_size, void* arg ) * */ wiced_rtos_create_thread(&stIcylinkerButtonThread, BUTTON_PRIORITY, "BUTTON", vButtonFunction, BUTTON_STACK_SIZE, NULL); wiced_rtos_init_semaphore(&stIcylinkerButtonSem); while(1) { WPRINT_APP_INFO(("<a href="https://www.eeboard.com/bbs/forum.php\n" ))"="">https://www.eeboard.com/bbs/forum.php\n"))</a>; WPRINT_APP_INFO(("user: icylinker\n")); WPRINT_APP_INFO(("board: BCM943364WCD1\n")); WPRINT_APP_INFO( ("----------------------------------------------------------------------------------------------\n" ) ); wiced_rtos_get_semaphore(&stIcylinkerButtonSem, NEVER_TIMEOUT); record_count = 0; WPRINT_APP_INFO( ( "Waiting for scan results...\n" ) ); WPRINT_APP_INFO( (" # Type BSSID RSSI Rate Chan Security SSID\n" ) ); WPRINT_APP_INFO( ("----------------------------------------------------------------------------------------------\n" ) ); wiced_time_get_time(&scan_start_time); wiced_wifi_scan_networks(scan_result_handler, NULL ); wiced_rtos_delay_milliseconds(DELAY_BETWEEN_SCANS); }}/* * Callback function to handle scan results */wiced_result_t scan_result_handler( wiced_scan_handler_result_t* malloced_scan_result ){ if ( malloced_scan_result != NULL ) { malloc_transfer_to_curr_thread( malloced_scan_result ); if ( malloced_scan_result->status == WICED_SCAN_INCOMPLETE ) { wiced_scan_result_t* record = &malloced_scan_result->ap_details; WPRINT_APP_INFO( ( "%3d ", record_count ) ); print_scan_result(record); ++record_count; } else { wiced_time_t scan_end_time; wiced_time_get_time(&scan_end_time); WPRINT_APP_INFO( ("\nScan complete in %lu milliseconds\n", (unsigned long )(scan_end_time - scan_start_time) ) ); } free( malloced_scan_result ); malloced_scan_result = NULL; } return WICED_SUCCESS;}void vButtonFunction(void *arg){ uint8_t button_status = 0; while(1) { switch(button_status) { case 0: if(!wiced_gpio_input_get(WICED_GPIO_2)) { button_status = 1; } break; case 1: wiced_rtos_delay_milliseconds(100); button_status = 2; break; case 2: if(!wiced_gpio_input_get(WICED_GPIO_2)) { button_status = 3; } else button_status = 0; break; case 3: wiced_rtos_set_semaphore(&stIcylinkerButtonSem); button_status = 4; break; case 4: if(wiced_gpio_input_get(WICED_GPIO_2)) { button_status = 0; } break; default: break; } }}</stdlib.h>四、运行结果
喜欢的点个赞！！！！ |
