先刨个坑 等视频上传好了再来填坑，吼吼 使用mx1081的AD模块，采集AD值，然后送wifi发送 使用UDP，简单快速明了，关键是人比较懒 虽然实现了，但是还有很多地方不是很明白 上代码，简单注释了一下main函数回复可见，哇咔咔 #include "stdio.h" #include "ctype.h" #include "MX1081_IO.H" #include "stm32f2xx.h" #include "platform.h" #include "mxchipWNET.h" #define ADC1_DR_Address ((u32)0x4001204C) void ADC1_CH1_DMA_Config(void); float AD_value_1; vu16 ADC_ConvertedValue[2]; #define LowPowerMode #define AP_NAME "Ljj@Home" #define AP_PASSWORD "xxxxxxxx" //我家的密码，就不告诉你，吼吼 #define APP_INFO "mxchipWNet Demo: Wi-Fi Link" network_InitTypeDef_st wNetConfig; net_para_st para; /* ======================================== User provide callback functions ======================================== */ void system_version(char *str, int len) { snprintf( str, len, "%s", APP_INFO); } void userWatchDog(void) { } void WifiStatusHandler(int event) { switch (event) { case MXCHIP_WIFI_UP: printf("Station up \r\n"); break; case MXCHIP_WIFI_DOWN: printf("Station down \r\n"); break; case MXCHIP_UAP_UP: printf("uAP up \r\n"); getNetPara(¶, Soft_AP); printf("Soft AP mode: IP address: %s \r\n", para.ip); printf("Soft AP mode: NetMask address: %s \r\n", para.mask); printf("Soft AP mode: MAC address: %s \r\n", para.mac); break; case MXCHIP_UAP_DOWN: printf("uAP down \r\n"); break; default: break; } return; } void ApListCallback(UwtPara_str *pApList) { int i; printf("Find %d APs: \r\n", pApList->ApNum); for (i=0;iApNum;i++) printf(" SSID: %s, Signal: %d%%\r\n", pApList->ApList.ssid, pApList->ApList.ApPower); } void NetCallback(net_para_st *pnet) { printf("Station mode: IP address: %s \r\n", pnet->ip); printf("Station mode: NetMask address: %s \r\n", pnet->mask); printf("Station mode: Gateway address: %s \r\n", pnet->gate); printf("Station mode: DNS server address: %s \r\n", pnet->dns); printf("Station mode: MAC address: %s \r\n", pnet->mac); } void stationModeStart(void) { int ret; memset(&wNetConfig, 0x0, sizeof(network_InitTypeDef_st)); wNetConfig.wifi_mode = Station; strcpy((char*)wNetConfig.wifi_ssid, AP_NAME); strcpy((char*)wNetConfig.wifi_key, AP_PASSWORD); wNetConfig.dhcpMode = DHCP_Client; ret = StartNetwork(&wNetConfig); printf("connect to %s....., return %d\r\n", wNetConfig.wifi_ssid, ret); } void softAPModeStart(void) { int ret; memset(&wNetConfig, 0x0, sizeof(network_InitTypeDef_st)); wNetConfig.wifi_mode = Soft_AP; strcpy((char*)wNetConfig.wifi_ssid, "Soft AP test"); strcpy((char*)wNetConfig.wifi_key, ""); strcpy((char*)wNetConfig.local_ip_addr, "192.168.0.1"); strcpy((char*)wNetConfig.net_mask, "255.255.255.0"); strcpy((char*)wNetConfig.address_pool_start, "192.168.0.10"); strcpy((char*)wNetConfig.address_pool_end, "192.168.0.177"); wNetConfig.dhcpMode = DHCP_Server; ret = StartNetwork(&wNetConfig); printf("Setup soft AP: %s, return %d\r\n", wNetConfig.wifi_ssid, ret); } vs32 tick = 0; vs32 button_irq = 0; void RptConfigmodeRslt(network_InitTypeDef_st *nwkpara) { if(nwkpara == NULL){ printf("Configuration failed\r\n"); } else{ printf("Configuration is successful, SSID:%s, Key:%s\r\n", \ nwkpara->wifi_ssid,\ nwkpara->wifi_key); } } char* itostr(char *str, int i) { sprintf(str, "%d", i); return str; } i
