and enable the counter
Wire 23 goes low then high, then wire 33 goes low then high
Read counter 0 to see how many counts have accumulated. - You
may wish to check for a null count.
Read the less-significant byte from pointer 1
Read the more-significant byte from pointer 1
Turn these bytes into a 16-bit value and subtract from 65535.
The result is the number of milliseconds.
This example shows how to measure the time that wire 23 of the
ribbon-cable is active (low).
Write B4H to pointer 12H to set the board control register
Make LK1B to feed 25kHz into the timebase.
Set the timebase counter to 25, to create a 1ms clock in mode 3
Write 36H to pointer 3
Write 19H to pointer 0
Write 00 to pointer 0
Write 70H to pointer 3 to put counter 0 into mode 0
Write FFH to pointer 1 to define the less-significant count byte and
stop the counter
Write FFH to pointer 1 to define the more-significant count byte
and enable the counter
Wire 23 goes low then high
Read counter 0 to see how many counts have accumulated. - You
may wish to check for a null count.
Read the less-significant byte from pointer 1
Read the more-significant byte from pointer 1
Turn these bytes into a 16-bit value and subtract from 65535.
The result is the number of milliseconds.
