Iosoft Ltd has announced the availability of the ER21 WiFi development kit, which is touted to be the first kit to provide a reference design for interfacing PICmicro MCUs to 802.11b and a lean web server, to provide a low-cost solution for Internet- and wireless-enabling real-time systems.

The kit is targeted at developers of home appliances and vending machines who wish to incorporate 'anywhere, anytime' duplex connectivity for monitoring, troubleshooting, and upgrades via the 802.11b WiFi standard.

"The standard nature of 802.11b WiFi offers electronic OEMs a remarkably flexible and cost-effective option for adding universal connectivity to products," said Jeremy Bentham, Chief Technical Officer of Iosoft. "This development kit gives designers the means to achieve that goal - with a suite of tools that can implement functionality ranging from remote alarms and monitoring, to design fixes and upgrades".

The development kit is a combination of a PCB with a PIC18xxx family MCU with Flash memory, in-circuit debug connector, and Ethernet and serial interfaces, linked to a commercial PCMCIA card for the 802.11b wireless network. The ER21 also allows the PICmicro-based embedded systems communicate in 'ad-hoc' (IBSS) or 'infrastructure' (ESS) WiFi modes.

It also comes with a circuit diagram and the company's Chipweb Wireless TCP/IP protocol suite for MCUs that also provides a lean HTTP web server and support for WEP encryption.
