Simple hardware Circuit

Wifi LED demo

At source code, you must change following text line to match your internet setting.
const char* ssid = "Magesh";
const char* password = "jayakumar";

You can connect this programmer with terminal software on PC / MAC.
Please open the serial port with baud rate at 115200 and data format as N81. All information show are in ASCII.

Web browser

You can see IP address at serial terminal software.
and type http://xxx.xxx.xxx.xxx on web browser.

 

 

Use ESP8266 Flasher tool and ESPlorer (Windows)

ESP8266 Flasher tool

1. config Baudrate in 115200

2. config flash size in 512kByte

3. config flash speed in 40MHz

4. open lua bootloader binary file eg."nodemcu_integer_0.9.5_20150318.bin".

5. offset 0x00000.

6. config COM Port.

7. Click Flash(F) for upload Boot loader program.

 

ESPlorer development tool (Windows)

Connect ESP-12 socket programmer with ESPlorer and run lua script

1 config Baudrate in 9600

2 Click Open button

3 write lua code on left window.

eg:

print("Hello, world")

4 Click Send to ESP

 

 

eg:-

 pin = 4 -- gpio pin
gpio.mode( pin, gpio.OUTPUT )
while 1 do 
	gpio.write( pin, gpio.LOW )
	tmr.delay( 500000 ) -- delay 0.5 second
	gpio.write( pin, gpio.HIGH )
	tmr.delay( 500000 ) -- delay 0.5 second
end
