timer.c is an example of programming esp8266 wifi chip using ESP8266 RTOS SDK. relay.c is the most advance version, which attempts to combine time and data into the switch logic. If data is outside of ...

An alternate solution is to buy ESP8266 chip separately, which is also much cheaper than NodeMCU board. With this option, you can directly burn the code into ESP8266 chip using a suitable programmer, ...

The ESP8266 is an inexpensive but powerful WiFi-enabled SoC. While official support (of the non-OS SDK) has been dropped, modules featuring the SoC (such as the LOLIN D1 mini v3.1.0) are still widely ...

Testing DeepSleep in the ESP8266. After uploading the program you will see that temperature readings are uploading on the ThingSpeak cloud after every 15 seconds and then module go in the deep sleep ...

During normal operation, we would want to use a resistor to pull GPIO0 high. 5 That will cause the bootloader inside the ESP8266 to read data from the EEPROM chip into the ESP8266’s IRAM and ...

A few months ago, the ESP8266 came onto the scene as a cheap way to add WiFi to just about any project that had a spare UART. Since then, a few people have figured out how to get this neat chip run… ...

At the heart of the ESP-01 module is the ESP8266 chip with at least two boot modes — the normal mode and the programming/flash mode. The latter refers to uploading any software (or firmware) to the ...

We just got our hands on some engineering pre-samples of the ESP32-C3 chip and modules, and there’s a lot to like about this chip. The question is what should you compare this to; is it more … ...

Moreover, if you have a sketch tailored for ESP8266, then you can run it on this board (Just ignore ATmega chip). Or you can use this board as an IoT development board to some extent. Keep note that ...
