• LCD Displays are a fast and inexpensive way to display simple information. This tutorial will demonstrate how to connect a 16x2 LCD display using I2C to an ESP8266 NodeMCU dev kit. The LCD display I'm going to use is fairly common and can be picked up for a couple of bucks from Amazon. It uses I2C to communicate with the NodeMCU.

  • Ctrl-A on a blank line will enter raw REPL mode. This is like a permanent paste mode, except that characters are not echoed back. Ctrl-B on a blank like goes to normal REPL mode. Ctrl-C cancels any input, or interrupts the currently running code. Ctrl-D on a blank line will do a soft reset. Note that ctrl-A and ctrl-D do not work with WebREPL.
SPI interface can also be used to connect external IEEE802.15.4 modules to integrate ESP8266 boards into a GNRC network. Other versions will not work because they do not have the necessary changes. Since we only use a few header files and some binary libraries, ESP8266 RTOS SDK does...

However, it is not officially supported, so any example sketch you find for another Arduino device may not work. The ESP is a workhorse, but it is not actually an Arduino, so some tweaks are needed. Also double check you are using the right pin. NodeMCU maps things differently. However after the update I can not connect to the module with minicom any more.Tried 9600, 57600 and 115200 Baud. Never get any response. After re-flashing firmware 00170901 to the device I can connect afain but I did not get the new version …. I tried the cloud update but mine also says ERROR after +CIPUDATE:4. I double-checked the connection. In the section "Changing the ESP8266-01 communication speed" he is trying to change communication speed with AT commands. Like described, I have uploaded an empty sketch and connected them like in that image: [With that pinout, the RED LED on the ESP8266 is not working and on the Nano I see TX is red. Why, well if you at the example above the LED is connected to what would be D13 on an Arduino but if you change to either D13 or 13 in the code, the example will not work. One of the other ESP32 boards may work differently the pins_arduino.h shows how the pins are defined, for example an Arduino. #define PIN_SPI_SS (10) #define PIN_SPI_MOSI (11) The file created normal but his timestamp is not expected.
