And you could easily just add a mc13224v to your hardware. All of the RF is integrated you only need to add the suggested antenna, a crystal, and power. You could interface to the CPU with SPI, I2C, or the UART. You can load the firmware over any of those interfaces and would never need to flash it. You'd want to hook up a GPIO line to reset. When you load the module, you'd load in a firmware image. You could offload a lot of the stack processing to the mc13224v if you'd like (for starters). You wouldn't have to wait for Contiki code to get pulled into linux that way. -Mar. ------------------------------------------------------------------------------ Create and publish websites with WebMatrix Use the most popular FREE web apps or write code yourself; WebMatrix provides all the features you need to develop and publish your website. http://p.sf.net/sfu/ms-webmatrix-sf _______________________________________________ Linux-zigbee-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/linux-zigbee-devel
