RS-R8C25-2200 – Ultra Low Power Wi-Fi Starter Kit for R8C/25 User Guide for Wi-Fi I/O Companion Card with R8C/25 2: System Overview The following diagram depicts the software architecture of the Connect-ion 1 module, RS9110-N-11-22, used in the Ultra Low Power Wi-Fi Starter Kit for Renesas Electronics’ MCUs. Renesas Host Controller (HOST) Application UART/SPI Driver UART/SPI UART/SPI Host Abstraction Layer SLIP Wireless Control Block Station Managment Entity TCP/IP WPA/WPA-2 802.
RS-R8C25-2200 – Ultra Low Power Wi-Fi Starter Kit for R8C/25 User Guide for Wi-Fi I/O Companion Card with R8C/25 As shown in the figure above, the Connect-io-n module is integrated with the Host using either UART or SPI interfaces 2 . The transmission and reception of the data to/from the Host depends on the interface used to connect the module as briefed below. UART mode: The Host transmits/receives raw data using UART interface when Connectio-n is configured for UART mode.
RS-R8C25-2200 – Ultra Low Power Wi-Fi Starter Kit for R8C/25 User Guide for Wi-Fi I/O Companion Card with R8C/25 3: Getting Started The system requirements for this demo are as follows: 1. RS-R8C25-2200 Wi-Fi Starter Kit 2.
