Upload Program in ESP12E / ESP12F using Node MCU

How To Program ESP12E / ESP12F using

 NodeMCU or ESP8266 in a Very Easy Way 

# Components Needed 

    1. Node MCU or ESP8266

    2. ESP12E or ESP12F

    3. Few jumper Cables

    4. 10k Resistor 2 pcs

# Circuit Diagram & Process 

Step - 1

💬 In ESP12E / ESP12F chip, Connect 10K resistor between EN/CH_PD and VCC 

💬 In ESP12E / ESP12F chip, Connect 10K resistor between GPIO15 and GND

Step - 2

💬 To bypass the Node MCU chip Connect EN / CH_PD with GND in Node MCU

Step - 3

💬 Connect the rest of the pins as per the Table ---

Step - 4

💬 To Add the ESP8266 Library

 

Enter this link into Arduino IDE

https://arduino.esp8266.com/stable/package_esp8266com_index.json 

into the File > Preferences > Additional Boards Manager URLs field of the Arduino IDE. You can add multiple URLs, separating them with commas.

After pasting the link goto --- 

# Tools > Board > Board Manager

# Search ESP8266 in the search box

# install ESP8266

# Select the board

# After Selecting the Board Write the code and upload it as usual 

# After uploading the Program We can Remove all the cables except VCC, GND, RESET, and the Resistors.

# For Power we have to give 3.3v maximum either it will be damaged.

Here is some information about the Pins & syntax of the ESP12E / ESP12F chip

# In ESP12E / ESP12F chip there are

    ----- 9 Digital Pins [ D0-D8 ]

    ----- 1 Analog Pin 

    ----- Default digital Pin is 2 [GPIO-2]

    ----- Syntax is (GPIO pin, OUTPUT)

 ##################################

When you use only ESP 12E or ESP 12F chip in your Project You have to connect a 10k resistor between RST and VCC, it prevents continue resetting.

##################################

Example ----

    digitalWrite(2, HIGH); 

    // Here GPIO-2 is used which is D4
