A Web server is a program that uses HTTP (Hypertext Transfer Protocol) to serve the files that form Web pages to users, in response to their requests, which are forwarded by their computers’ HTTP clients.
To implement web server on ESP, there are two ways to make your first web server first connect to your WiFi router or make ESP as access point. Continue reading ESP8266 Web Server
In this tutorial we will see writing data to EEPOM and reading from EEPROM. ESP8266 have 512 bytes of internal EEPROM, it is useful when you want to store some settings, such as IP address of server, WEP key, SSID of WiFi. We also discuss on writing string into EEPROM and reading it.
To write byte to EEPROM we need two commands Continue reading ESP8266 Internal EEPROM Programming
Serial interface is common requirement for most of the application development. We are discussing on how to do 3.3V to 5V level conversion for converting serial TTL to RS232 level from 3.3V you can use MAX3232 it operates at 3.3V levels.
On ESP8266 we have one hardware serial i.e. GPIO2 (Tx) and GPIO3 (Rx).
Hardware Serial Programming is similar to the Arduino Serial. Remember that few USB to Serial converter does not support higher baud rate. It is better to keep baud rate below 115200. Continue reading ESP8266 Serial Communication
Software serial uses timer, be careful when you are using software serial. Timer is also used for WiFi communication section if you don’t give enough time to WiFi routines it will create problem of stack error or misbehavior. It is better to use software serial only when you need two serial ports and also avoid use of software serial for data reception.
Software serial can be implemented on any GPIO pin of ESP8266. Continue reading ESP8266 Software Serial Communication
This is our first program for ESP8266 Getting Started series. Assuming that you have prepared hardware as per Figure (Complete Hardware setup for ESP8266) or you can use node MCU, ESP witty.
In this program we will blink on board LED i.e. present on GPIO2 (TX) pin. Continue reading ESP8266 LED Blink
