Here is the I\/O map in SPLat equate format for the DC216<\/p>\n\n\n\n

There’s some really good technical information about\u00a0using digital pins as outputs<\/a>.<\/p>\n\n\n\n

The 8 digital I\/O terminals are all active low, inactive o\/c (open circuit).  You do not need to specifically configure them as inputs or outputs, they are simply always inputs and always outputs.  Be aware that to use a pin as an input, be sure not to use an output instruction to turn it on, otherwise it will switch low and can’t be used as an input.<\/p>\n\n\n\n
As a side note, separation of the LED into on\/off and green\/red pins allows for some cute effects.  For example:<\/p>\n\n\n\n
\n
On      oLedOn
Blink   oLedGreen
<\/pre>\n<\/div><\/div>\n\n\n\n
These two instruction will cause the LED to automatically start blinking between red & green.<\/p>\n\n\n\n
Quadrature Counter<\/h6>\n\n\n\n
A high speed quadrature counter is supported on inputs 3 and 4.  The quadrature signals should switch between open-circuit and ground.<\/p>\n\n\n\n
Terminals 3 & 4 are always available as bi-difectional inputs & outputs, the quadrature counter is always running in the background.<\/p>\n\n\n\n
It can theoretically cope with a signal of over 10MHz, but wiring and circuit board loads may limit the maximum attainable frequency.<\/p>\n\n\n\n
