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

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.

Remember a painful lesson, remember to save the file instantly. (This time not lost, but not build). Remember, remember that eclipse must be ctrl+s and clean before build. 1, the purpose of the experiment Learn about the STA mode operation method

1. SendCall Uart_init (115200,115200); Initialize the serial port, the baud rate is set to 115200. The previous one is setting the baud rate of the uart0, followed by the setting, the UART baud rateYou can then use Uart0_tx_buffer (uint8 *buf, UInt16

Emmmm, this piece of information is very large, is a comprehensive process, if there is doubt to remember to check the contents of the front, check leakage fill. file operations, save the data so that you can arbitrarily modify which mode to work at
