On the board of NODEMCU, there is the other LEDs what can be tested. 1. First LED Through the PCB file of NODEMCU (see Figure-1 or Https://github.com/nodemcu/nodemcu-devkit-v1.0/blob/master/NODEMCU_DEV Kit_v1.0.pdf), we can find the first led which connected by GPIO16 and vdd3v3. The index of PIN is 0. (see another ar

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 i

The NODEMCU is a compact development board with integrated WiFi and MCU, based on the ESP8266 chip. Forum in http://bbs.nodemcu.com/, source code in HTTPS://GITHUB.COM/NODEMCU.Using the Openscad to make a shell, you can use the 3D printer output, and no longer "bare-Ben".OPENSCAD's original model file is as follows, which can be modified and output on the 3D printer itself.NODEMCU Smart Device, box, Rainproof (vertical mount)//author:[emailprotected],

NODEMCU's documentation finally found that ESP8266 's GPIO 2 is indeed a PIN 4,gpio 0 is pin 3. Https://github.com/nodemcu/nodemcu-firmware/wiki/nodemcu_api_cn In other words, this API is not for the Earth people to see. According to the instructions, Net.createserver returns the Server, in fact, if using UDP, according to the code inside you do not work out. Finally found the answer in the Www.esp8266.com

Because arm's device performance is still low, generally not suitable to run the IDE, code editing, compiling, packaging and other work, so generally on the PC built a " cross-compilation Environment ", compiled program, into a binary package, and then burned to write in.

Due to the widespread use of the COM protocol, many devices, although the interface changed to USB, but the internal data communication protocol is still using COM (that is, the traditional RS232 serial port protocol, the new use of TTL). Many devices use PL2302/CH340/FTDI and other chips to simulate the serial port protocol via USB, such as ARDUINO/NODEMCU, etc., using a similar mechanism.Under Windows, after you install the driver, you can find the
