====== Compare ======

''Compare channel, target#, port, targetState''
| //channel// | High-speed counter channel |
| //target#// | Target # of pulses (CH0: 0 to 65535, CH1: 0 to 255) |
| //port// | Output port (DO NOT USE input-only ports) |
| //targetState// | Target output port state |

When the high-speed counter value reaches  a  set  target  point  (''target#''), the processor will set an I/O Port to logic low or logic high.

{{ :cubloc:compare:compare.png?nolink |}}

If ''targetState'' is set to 1 and the target number of pulses (''target#'') have been received, the output port (''port'') will output logic high. Likewise, if the ''targetState'' is set to 0 and the target number of pulses (''target#'') have been received, the output port(''port'') will output logic low.

^  Channel         ^  Compare Range  ^
| HCOUNT Channel 0 | 0 to 65535      |
| HCOUNT Channel 1 | 0 to 255        |

The high-speed counter itself supports up to 32-bits, but the ''Compare'' is limited since this command was designed to not affect the overall multitasking of Cubloc's main processor. Note: For channel 0, please use the ''Set Count0 On'' command before using ''Compare''.

<code xbasic>
Dim i As Integer
Set Count0 On
compare 0,10,61,1
Do
  i = Count (0)
  Debug Goxy,0,0,dec4 i,Cr
  Delay 100
Loop
</code>

The above uses high-speed counter channel 0 with a target of 10 pulses. When the counter value becomes 11, the output port (port 61) will output logic high.
