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

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
