v30 v31 34 34 * Raised CSMA threshold from 6000 to 8192. This is more in line with 802.11 and should make nodes more aggressive in the presence of non-decodable interference 35 35 36 '''Using the Design''' 37 * The CSMAMAC code uses the UART to control various parameters at run time. Use a terminal emulator set to 57600bps. The following commands are implemented by default: 38 * '''E'''/'''e''' : Increase/decrease the packet detection energy threshold by 100 39 * '''D'''/'''d''' : Increase/decrease the packet detection required minimum energy duration by 1 40 * '''C'''/'''c''' : Increase/decrease the 2.4GHz center frequency by 1 channel 41 * '''2'''/'''3''' : Use the radio in slot 2/3 for the SISO link 36 42 37 38 39 43 * The new interrupt-free design requires some minor modifications to user code from reference design v11.2 44 * Call warpphy_pollPeripherals() in the main while(1) loop (instead of warpphy_pollEthernet()). 45 * User code should still register callbacks for the various events (PHY good/bad Rx, timers, UART, user I/O); WARPMAC will execute these callbacks same as before (even though it's driven by polling instead of interrupts). 40 46 41 47 == OFDM Reference Design v11.2 (2008-Dec-1) ==
