WINC1500 HTTP POST/Get Example Project

This is an example project code of HTTP Post/ Get feature on WINC1500 Wi-Fi module

Description

This reprosoitry is WINC1500 HTTP Post/Get example project code. This demonstrate the use of HTTP Get/ Post Method to download or upload data to the HTTP server through WINC1500 Wi-Fi module. The HTTP POST include the data upload using HTTP content-type "application/x-www-form-urlencoded" and the file upload using HTTP content-type "multipart/form-data"
The project code is running on SAMD21 XPRO board and WINC1500 XPOR board.

Configuration

HTTP Configuration

The demo can be configured to download a file using HTTP GET, upload test data or upload file using HTTP Post.
You can change the macro defination in main.h to select the HTTP METHOD

//#define TEST_HTTP_GET
//#define TEST_HTTP_POST_FILE
#define TEST_HTTP_POST_VALUE

POST Method URL can be configured in below defination in main.h

#define MAIN_HTTP_POST_URL                   "http://xxxxxxxxxxxxxxx"

Wi-Fi Configuration

You can set the SSID and password in main.h to provision the WINC1500 device to the target network

/** Wi-Fi AP Settings. */
#define MAIN_WLAN_SSID                       "Demo_AP" /**< Destination SSID */
#define MAIN_WLAN_AUTH                       M2M_WIFI_SEC_WPA_PSK /**< Security manner */
#define MAIN_WLAN_PSK                        "12345678" /**< Password for Destination SSID */

Hardware Setup

SAMD21 XPRO board and WINC1500 XPOR board are needed to run the demo. Beside, IO1 XPRO Extension Kit with micro SD card is also needed if you are testing HTTP Get (TEST_HTTP_GET) or HTTP Post File (TEST_HTTP_POST_FILE)

You can order ATWINC1500-XSTK Xplained Pro starter kit from microchip website. This kit include all the hardware needed for this demo.

Connection

1. Plug the WINC1500-XPRO into the SAMD21-XPRO board in the EXT1 location.
2. Plug the IO1-XPRO into the SAMD21-XPRO board in the EXT2 location.
3. Connect the DEBUG USB port of the SAMD21-XPRO board to the host computer using a Type A to Micro B USB Cable

Build and Test

1. Lauch Atmel Studio
2. Click File > Open > Project, select WINC1500_HTTP_EXAMPLE.cproj
3. Click Debug > Start Without Debugging to build the project and download the program to the EVB
4. Start up a UART terminal emulator like TeraTerm and open the EDBG COM Port connection with the following settings:

• Baud rate: 115200
• Data: 8 bit
• Parity: None
• Stop bits: 1
• Flow control: None

5. After program firmware successfully, the below log is shown in the SAMD21 console:

-- WINC1500 HTTP Client example --
-- SAMD21_XPLAINED_PRO --
-- Compiled: Mar  1 2021 18:17:20 --

This example requires the AP to have internet access.
