Renesas Electronics customers can add Wi-Fi connectivity using GainSpan's GS1011M and GS1500M low power Wi-Fi modules and develop their solutions with the Wi-Fi Adapter Boards, evaluation boards and drivers from GainSpan. All the GainSpan solutions work seamlessly with Renesas MCUs.
The Wi-Fi Adapter Boards come in two configurations: the WAB-GW-GS1011MIP, an ultra-low power 802.11b solution based on the GS1011MIP and the WAB-GW-GS1500M an 802.11b/g/n solution based on the GS1500M module. The modules plug into the Renesas development boards through the Application Header Interface or PMOD connectors that are used, for example, on the RL78 and RX62/ RX63 Renesas Demo kits (RDK). For other Renesas development boards, GainSpan offers evaluation boards that interface through an RS-232 connector.
GainSpan provides also drivers for most Renesas microcontrollers including the RL78, RX62, RX63, V850, SuperH, 78K0 and 78K0R and due to their small footprint may be used with the IAR Embedded Workbench Kickstart Edition. Drivers for other Renesas MCU's are also in development. Drivers are available for UART or SPI interface:
Demo code is also available to display RDK sensors information on iOS and Android devices.
Serial to Wi-Fi Adapter Boards provide the means to evaluate the capabilities of the GainSpan low power Wi-Fi modules, Serial to Wi-Fi embedded software as well as the development of Wi-Fi enabled devices using Renesas microcontrollers. The Serial to Wi-Fi Boards are designed to plug directly into Renesas Development Kits (RDK) through the Application Header Interface or the PMOD interface.
The Wi-Fi adapter boards are available in two configurations:
The boards provide both UART and SPI interfaces, making it possible to connect to any Renesas microcontroller using simple AT commands Additionally, the boards have built-in flash for reliable over the air firmware upgrade and factory restore configuration.
The GS1011MIP and GS1500M modules mounted on the Wi-Fi Adapter Boards offer customers easy system integration and minimal use of host resources. The modules are pre-loaded with serial to Wi-Fi firmware with complete Wi-Fi functionality including security, WPS and provisioning features running on the module as well as the networking stack, an embedded HTTP server with network configuration pages, and limited AP capability for ease of provisioning. The host microcontroller is hence offloaded from Wi-Fi and networking functionalities and could be dedicated to customer applications. A small driver of only a few Kbytes is required to run on the host, making the solution suitable for even the most processing and memory constrained MCU's.
The drivers are small enough to be used with the IAR Embedded Workbench / Kickstart Edition.
