WICED™ SDK support

WICED™ is a Cypress development system that vastly reduces the effort required to add wireless connectivity to embedded devices. The SDK enables developers to quickly create network connected applications targeted for low-resource microcontrollers.

The WICED™ SDK includes:

  • - An open source build system and toolchain based on GNU make.
  • - A GUI IDE based on Eclipse CDT that seamlessly integrates with a programmer and single-step, thread-aware, debugger based on OpenOCD and gdb.
  • - A complete software stack that includes advanced security and networking features such as SSL/TLS, IPv4/IPv6 networking, and mDNS/Bonjour.
  • - Production ready example applications.

SN820X supports WICED™ SDK
WICED SDK platform patch file download:
WICED SDK version 2.4.1 For all the SN820X Modules.
WICED SDK version 3.0.1 For SN8205, SN8205UFL only.
WICED SDK version 3.1.0 For SN8205, SN8205UFL only.
WICED SDK version 3.1.2 For SN8205, SN8205UFL only.

Murata Simple Network Interface Controller (SNIC) and EZ Web Wizard™ Software

Based on Cypress WICED™ solution, Murata offers pre-built firmware/software package that makes the host integration, wireless and peripheral control more easier and reliefs the burden of firmware programming

Murata Simple Network Interface Controller (SNIC) protocol supports socket interface on both UART and SPI to host

Example for TCP data communication:

    - WiFi on request
    - WiFi join request
    - SNIC Init request
    - SNIC IP config request
    - TCP create socket request
    - TCP create connection request
    - Send from socket request
    - Close socket request
    - SNIC cleanup request
    - WiFi disconnect request
    - WiFi off request

Murata EZ Web Wizard™ (EWW) software supports easy custom web-based control to save the cost on additional host microcontroller

  • - Control I/O interfaces through HTML, JavaScript and JSON
  • - Support UART, I2C and GPIOs
  • - Support wireless network configuration, JSON parser, HTTP server, TCP/IP network stack, and WiFi driver
  • - Enabling the creation of wireless IP-capable nodes
