抱歉我的英语不好。
我对Shield和Arduino UNO之间的通信有问题。这些是图像:
Wifi shield使用FTDI程序员与Arduino IDE进行通信。引脚已正确连接。当我想在屏蔽上添加代码时,“红色小盒子”上的引脚分别是1-DOWN,2-DOWN,3-UP,4-UP,所以一切都还好。当我使用Arduino IDE中的示例来获取Wifi AP(文件 - >示例 - > ESP8266WiFi - > WifiAccesPoint)并将其上传到WiFiShield时,我可以在手机上看到WiFi网络。这是代码:

当我按下按钮时,我可以从Arduino IDE的串行监视器中看到来自WebPage的消息,说明:“点击”
现在,存在大问题。当我将屏蔽连接到Arduino时,wifi网络仍然可见,我可以按下按钮,因为FTDI始终与USB COM10通信(在我的情况下)。
然后,当我将Arduino UNO连接到USB端口时,wifi网络仍处于活动状态。
但是当我使用FTDI与USB断开使用Wifishield通信时,仍然连接了Arduino UNO电缆,WiFi网络消失了。
所以,我只想将Arduino UNO连接到usb Arduino IDE,我想看到用wifi屏蔽创建的wifi网络可见。然后它将始终可见(同样当wifishield断开连接时,只连接UNO)我希望它发送消息,在这种情况下消息“Click”到Arduino UNO串行监视器。有任何想法吗?非常感谢你!
答案 0 :(得分:1)
我认为您应该检查电缆,两个端口:ard Tx,Rx-usb Tx,Rx
