Simple REST Web server library for small IoT devices. Users can be made the IoT device for REST-based web services available in this project using C language / WIZwiki-W7500ECO platform board.

For more details, please refer to WIZ550web Wiki page in WIZnet Wiki.

• Keil uVision5 IDE v5.10

Build and Firmware write to target board: WIZwiki-W7500ECO

KEIL uVision5 project file can be found in below file path.

• $Projects/HTTP_Server_RESTAPI/W7500x_App.uvproj

• Writing firmware into WIZwiki-W7500ECO has three ways
  • Using the CMSIS-DAP (Drag and Drop)
  • Using the CMSIS-DAP (through KEIL uVision5)
  • Using the ISP (ISP, In-System Programming)

For more details, please refer to WIZnet wiki site.

• All resources(URI) are represented in lower case letters.
• REST API Document is under construction. It will be update continuously.

[:id] : pre-defined 4-I/O pins, 'a', 'b', 'c', 'd'.

• 'a' : P30 pin (digital input / digital output / analog input)
• 'b' : P29 pin (digital input / digital output / analog input)
• 'c' : P28 pin (digital input / digital output / analog input)
• 'd' : P27 pin (digital input / digital output / analog input)

• Device uptime

http://w7500xRESTAPI.local/netinfo

• Network information (e.g., MAC / IP address ...)

http://w7500xRESTAPI.local/userio

• All active user IO's ID / Type (Digital or Analog) / Direction (Input or Output)

http://w7500xRESTAPI.local/userio/:id

• Get the User IO's status or value

http://w7500xRESTAPI.local/userio/:id/info

• Get the user IO's ID / Type / Direction

http://w7500xRESTAPI.local/userio/:id

• Activate (Create) the specified IO

http://w7500xRESTAPI.local/userio/:id

• Set (change) the User IO's status (digital output only)

http://w7500xRESTAPI.local/userio/:id/info

• Set (change) the User IO's Type / Direction

http://w7500xRESTAPI.local/userio/:id

• Deactivate (Delete) the specified IO

Connect your board to your network and run test tool. These library has been tested on Postman Builder.

GET http://w7500xRESTAPI.local

• Results: It returns all resources list supported by the board as representation in JSON.
  • Includes defined id list for I/O pins
• URL '/' is substituted with '/index', Thus, this URL is recognized as [http://w7500xRESTAPI.local/index]

GET http://w7500xRESTAPI.local/netinfo

• Results: It returns board's network setting like MAC / IP address as representation in JSON.

GET http://w7500xRESTAPI.local/userio

• Results: It returns setting of activated IO on board as representation in JSON. Each IO's JSON object includes three-keys. (ID / Type / Direction)
