    v30 v31  
    3434 * 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
    3535
     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
    3642
    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).
