Uart-wifi Module ESP8266
Because it is only a module, not a complete development board, so you need to connect the peripheral circuit. The trial process encountered a lot of trouble, here all record.
1. Confirm Hardware Version
Since the ESP8266 version has been updated, so you need to confirm the PCB version.
Features: The middle four IO ports are wired to connect out.
2. Hardware connection
If confirma

In general, the gr/IR account must be balanced, but in some special cases, the gr/IR account may be unbalanced. Therefore, you need to adjust the gr/IR account.
The first case: "GR is smaller than IR", which means that the system will expect further GR or balance the gr/
Previously found on the forum a ESP8266 can control the GPIO0 firmware and app, but do the home AV lighting system is required to control multiple IO to control the STM32. Learn about Gpio control methods by watching Daming's video.The data is received in the APP\USER\AT_IPCMD.C of the firmware. By identifying the sent over is the string G P I O 0 = 0 and then the corresponding Gpio settings.A number of workarounds are shown in the GPIO4 operation. Th

Download the Esp8266 firmware and its download tools from the attachment first, asLink: Http://pan.baidu.com/s/1jI8iIwA Password: q6yz2. Open the Burn-write tool, select 0x0000 and
Set the name and password of the WiFi module (AP mode)At+cwsap= "ESP8266", "1234567890", 5,3
This module can operate in three modes: 1. STA 2. AP 3. Ap+sta, factory set to the third type
STA mode: Station, similar to the wireless terminal, the STA itself does not accept wireless access, it can connect to the AP, the general wireless network card is working in the mode. At+cwmode=1/2/3
The following is an example of establishing a TCP server as a
Previous blog: http://www.cnblogs.com/bentuwuying/p/6681943.html briefly introduced the basic principles of learning to rank, and also talked about learning to Rank's several common methods: Pointwise,pairwise,listwise. This blog is an introduction to the pairwise methods commonly used by many companies in practice, and first we introduce relatively simple RANKSVM and IR SVM.1. RANKSVMThe basic idea of RANKSVM is to transform the sorting problem into
Always want to engage in smart home aspects of things, smart home can not be separated from the network control, before a period of time arduino+esp8266 solution, found that this way stability is poor, often appear communication errors and transmission problems, access to some information, Discover the ESP8266 module inside itself can do some simple processing, and then began the

Digital TV-DTV is no longer a new thing for us. On-board electronics, DTV mostly exists independently in the form of modules and is configurable. In the on-board market, the customer's needs are diverse. If DTV is used as the on-board navigation main PCB, it is still not flexible. If DTV is not used, it must be different PCB boards, this is not a good solution for after-sales maintenance and development.
DTV is at home, and we usually operate through the remote control. Of course, some android T
DescribeAn Apple Watch and iphone app for controlling any infrared device. The iOS app sends an HTTP request to one or more Arduino with an Ethernet board. Arduino is parsing an HTTP request and sending an infrared signal. The Arduino code is based on the Irremote Library (https://github.com/shirriff/Arduino-IRremote). I use a triple infrared emitter to send infrared signals to multiple devices.DetailedProblems encountered:I need to use 5 different remote controls to control my media device!Solu
