 * The HTTP server provides a small scripting language.  *  * The script language is simple and works as follows. Each script line starts  * with a command character, either "i", "t", "c", "#" or ".".  *   "i" - command tells the script interpreter to "include" a file from the  *         virtual file system and output it to the web browser.  *   "t" - command should be followed by a line of text that is to be output  *         to the browser.  *   "c" - command is used to call

应用背景The CMX990 provides, on-chip: a flexible, formattable GMSK packet and freeformat modem, a dual synthesiser fed from an external source, IF and RF transceiver stages for both Rx and Tx modes, and auxiliary ADCs and DACs for system control and monitoring.关键技术Operating in the range of 400MHz to 1GHz at data rates of 4 to 16 kbps. This single-chip, half-duplex device requires a minimum of external components, keeping end-product board size, power consumption and cost to an absolute minimum. The versatile GMSK modem is configured for either packet and freeformat data operation via an efficient task-oriented Rx and Tx format and command structure combined with data scrambling, interleaving and FEC and CRC capabilities. Rx data acquisition, extraction and tracking functions use Rx data-quality feedback to support varying signal environments. IF and RF functions in the Tx path handle all the signal processing requi
