Now we are going to learn how we can interface the ESP8266 WiFi Module with ARIES v2 Board. The ESP8266 is a low-cost Wi-Fi microchip, with a full TCP\/IP stack and microcontroller capability. This small module allows microcontrollers to connect to a Wi-Fi network and make simple TCP\/IP connections using Hayes<\/a>-style commands.<\/p>\n\n\n\n

ESP8266 WiFi Module<\/h2>\n\n\n\n

ESP8266 is a highly integrated chip designed for the needs of a new connected world. It offers a complete and self-contained Wi-Fi networking solution allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor. ESP8266 has powerful on-board processing and storage capabilities that allow it to be integrated with the sensors and other application-specific devices through its GPIOs with minimal development up-front and minimal loading during runtime.<\/p>\n\n\n\n

Its high degree of on-chip integration allows for minimal external circuitry. It is designed to occupy a minimal PCB area.<\/p>\n\n\n\n

Circuit Diagram<\/h2>\n\n\n\n

ESP8266 Module communicates with the ARIES v2 Board via the UART Protocol. Connect VCC and GND to +3.3V and GND respectively. Connect RX <\/strong>to UART1-TX<\/strong> and TX <\/strong>to UART1-RX<\/strong> pins. <\/p>\n\n\n\n

Now, for powering up and programming the code into the ARIES v2 Board, we have to connect a micro USB type B<\/strong> (common data cable, used for mobile charging and data transfer) in the UART0<\/strong> port of the ARIES v2 Board, to a Laptop\/Desktop\/PC with preinstalled VEGA SDK and Toolchain.<\/p>\n\n\n\n

Procedure<\/strong><\/h2>\n\n\n\n

After setting up the toolchain and SDK path environments, build the example program for the ESP8266 Module by :<\/p>\n\n\n\n

cd vega-sdk\/examples\/uart\/wifi_demo<\/code><\/pre>\n\n\n\n
make clean <\/strong>command to clean the executable :<\/p>\n\n\n\n
make clean<\/code><\/pre>\n\n\n\n
then use make<\/strong> command to build it.<\/p>\n\n\n\n
make<\/code><\/pre>\n\n\n\n
Now, we can transfer the built program to the board, before transfer please ensure that you have connected UART0 connector of the board to the PC.<\/p>\n\n\n\n
Open a new terminal and execute the following command.<\/p>\n\n\n\n
sudo minicom aries<\/code><\/pre>\n\n\n\n
Now you can see the minicom terminal opened and the board uart terminal is ready.<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
Use CTRL+A S to enter file sending menu and select xmodem by pressing Enter.<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
In the next window, with the Space bar<\/strong> select the wifi_demo.bin<\/strong> file to be transferred, by pressing Enter<\/strong>, the transfer process starts.<\/p>\n\n\n\n
Wait until the process is completed. The screen should display how much data has been transferred.<\/p>\n\n\n\n
After completing transfer the Program will start to execute.<\/p>\n\n\n\n
The output is displayed in minicom UART terminal:<\/p>\n\n\n\n

Connect to the Wifi network and then try accessing the webpage 192.168.4.1<\/p>\n\n\n\n
Try  to toggle LED by ON\/OFF switch<\/p>\n\n\n\n
