   description: Oscilloscope 4/8ch Logic Display
   written by : Michael Bradley

   Changelog:
      08/01/09 added alt/chop mode
      07/31/09 v1.2 Changed pic from 18f2525(10mip) to an 18f26k20 (16mip)
      07/23/09 Setup for 4/8 ch mode. Ground SEL_TRACE for 8 ch mode 
      07/19/09 Optimized code for faster speed
               was 150us per ladder iteration, under 60us now
      05/04/09 Addred SYNC_OUT pulse, starts at each cycle of ladder
      10/01/08 Fixed trace floor and roof
      09/30/08 Updated with MX7224 DAC, 8bit parallel, SPI was way too slow
               DAC0-7 connected to Port C0-7
      09/16/08 Prj Begin, using SPI DAC
