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:
SN820X supports WICED™ SDK
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 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
