// Rev 4.7 8/31/2010
// 1. Added waveform #15 per Niraj Desai data for CM2250....ISBe4...mod of #13.

// Rev 4.6 3/10/2010
// 1. Added waveform #14 (60-2 / 6+1 / 6+1)
// 2. Fixed Set_Addr() function to handle multiple sync'd channels correctly, and 
//    fixed waveform #14 by adding wave[6].length to definition in switch() statement

// Rev 4.5 5/13/2008...released Nov 2009
// 1. Fixed waveform #12 (142 / 6+1)
// 2. Added waveform #13 (60-2/4+1)

// Rev 4.4 3/2008
// 1. Added waveform #11 (60-2/8+1)
// 2. Added waveform #12 (142 / 6+1), but has problems
// 3. Changed Generate_Waveform function to allow use of old (non)inverted bitmaps

// Rev 4.3 8/10/2007
// 1.  Corrected several closed loop engine speed probs
// 2.  Changed engine model design

// Rev 4.2 7/31/2007
// 1.  Added waveform 7 & 8 (QSB, QSC)
// 2.  Allow arb card to be used as digital card

// Rev 4.1 3/22/2007
// 1. Added sync offset change.  Only good for channels 1&2. Can use offset
//    for one or the other, but not both.  this is 'cause i'm forcing one to addr 0
//    (should read addr, but have to wait 900ms for CPLD to reset spi after a read)

// Rev 4.00 3/14/2007 (req rev2 FPGA/CPLD)
// 1. Added PWM functionality 

// Rev 3.15 
// 1.  Fixed waveform 1-off loading issue with old CPLD/FPGA SPI code

// Rev 3.14 2/16/2007
// 1. Changed waveform #1 and #5 cam signal to correct sync

// Rev 3.13 2/15/2007
// 1. Change to not re-load waveform if rx 0x51 msg with same
//    waveform that's in use.

// Rev 3.12 2/9/2007
// 1. Added waveform #6 (60-2/24+1) and #9 (repeat of #5)

// Rev 3.11 12/19/2006
// 1.  Corrected sw ver msg by adding parenthesis
// 2.  Ignore 0x50 msg for channel 2
// 3.  Ignore 0x50 & 0x51 msgs for invalid channels
// 4.  Add busoff & busserr interrupt/clear

// Rev 3.00 12/18/2006
//
// 1.  Added capability to switch waveforms on the fly via CAN
// 2.  Added SW ver info to ping response
// 3.  Added 60-2/12+1 waveform combo
