申请开发板时准备用做一个智能家居的控制中心,需要的时间太长，很快就要到发实战的截至日期了，就先做了个DEMO功能出来，不然板子就得被收回了~
主要功能：
通过手机或电脑在局域网内控制 469 Discovery 的5个LED，包括 LD1 LD2 LD3 LD4 LD7, LD7。
硬件组成：
STM32F469 Discovery + LBP100 WIF模块
LBP100 WIF模块由上海汉枫生产，可以通过 smart link 软件来配置其连接到路由器，具体的资料可以从其官网下载。外观如下：
通过漆包线连接排针插到 STM32F469 Discovery 的Arduino uno connector接口，电路如下：
模块控制引脚连接：
电源引脚：
实物图：
USB转UART接口用来监测WIFI模块向MCU返回的数据。
使用 ST Link 的虚拟串口作为调试信息打印接口。
软件主要流程：
1初始化LED
2配置WIFI模块
3搭建TCP SERVER
4解析、执行指令
主函数：
int main(void)
{
debugInit();
debug_log("*****************21ic*****************\r\n");
debug_log("* STM32F469IN_Discovery Board ʵսÈÕ¼Ç 1 *\r\n");
debug_log("* ---------- ÖÇÄÜLED Demo ---------- *\r\n");
debug_log("************************************************\r\n");
debug_log("all led init\r\n");
all_led_Init();
debug_log("wifi init\r\n");
wifiInit();
while(1)
{
ledControlDetect();
delay(500);
}
}
void wifiInit(void)
{
LPB100_IO_init(); //³õʼ»¯IO
LPB100_RELOAD_PIN_SET(); //À¸ß nReload ·ÀÖ¹WIFIÄ£¿é»Ö¸´³ö³§ÉèÖÃ

//µÈ´ý WIFI ready
while(1 == LPB100_READY_PIN_STA()) //LPB100 Æô¶¯Íê³Éºó Ready PIN Êä³ö0
{
debug_log("wait wifi ready...\r\n");
delay(5000);
}
debug_log("wifi is ready\r\n");
if(GPIO_ReadInputDataBit(GPIOA,GPIO_Pin_0)) // userKey °´Ï WIFI»Ö¸´³ö³§ÉèÖÃ
{
debug_log("clear LPB100\r\n");
LPB100_RELOAD_PIN_RESET();
delay(30000);
LPB100_RELOAD_PIN_SET();
delay(10000);
//µÈ´ý WIFI ready
while(1 == LPB100_READY_PIN_STA()) //LPB100 Æô¶¯Íê³Éºó Ready PIN Êä³ö0
{
debug_log("wait wifi ready...\r\n");
delay(5000);
}
debug_log("wifi is ready\r\n");
}
wifi_link_detect(); //wifi Á¬½Ó¼ì²â

intoDirectTranfser(); //wifi Ä£¿é»Øµ½Í¸´«Ä£Ê½
