This is the use of this paragraphBecause this default is the firmware that supports the AT command, so we're going to brush Nodemcu'sFirst look at the wiringGPIO0 default is operating mode (no wiring). If the next low level is the download mode (to the module brush firmware!!) ) So the low level is connected. CH_PD high level, the rest can not be wired except TX,RX.The rest is actually almost the same as my article NODEMCU preliminary studyThe first is to download the tools and firmware you need

In short, there are too many problems.The most important, but also the most annoying problem is: brush does not enter the program, brush not into the program.I use a lot of software:In the end, still can not solve the problem, the basis is half upload, can not upload.

ESP8266-01 is a powerful module that can meet the needs of any of our IoT projects. Since its release, it has formed a very powerful community and evolved into an easy-to-use, inexpensive and powerful Wi-Fi module. Another popular open source platform is the Arduino Development Board, which has built up a large number of projects around the platform. Combining these two platforms will open the door for many innovative projects, so in this tutorial we

Brief introduction DB2 UDB provides a framework for writing custom security plug-ins that administrators can use to perform DB2 UDB authentication. This framework is introduced in the DB2 UDB V8.2, and also supports plug-in authentication based on the Universal Security Service Application Programming interface (Generic, application programming Interface,gss-api). Many DB2 UDB administrators use the GSS-A
