It does not use interrupts.
4.3.2 Digital IO — INOUT.EXE
The “IN OUT” example demonstrates basic Digital IO using the 82C55 peripheral port interface. It
runs on all supported Amplicon cards that have PPI resources, PC212E, PC214E, PC215E,
PC263, PC272E, PC30AT, PC36AT, PC36LP, PCI215, PCI230, PCI236, PCI263 and PCI272.
It allows the user to select PPI ports as inputs or outputs, set outputs high or low and monitor their
actual state.
It is equivalent to the Visual Basic “INOUT” example.
It does not use interrupts.
4.3.3 Digital IO With Interrupts — PDIO_EX.EXE
The “Extended DIO” example demonstrates sending buffers of information to the 82C55 PPI
interface under interrupt control. A strobe pattern is played out the PPI port. It runs on the PC212E,
PC214E, PC215E, PC30AT, PCI215 and PCI230 cards. It is equivalent to the Visual Basic
“DIO_EX” example.
It requires that the cards be installed with interrupts.
4.3.4 Voltmeter — METER.EXE
The “Meter” example is a multi-channel voltage meter example. It runs on the PC26AT, PC27E,
PC30AT, PCI230 and PCI260 cards. Care must be taken to set up any card jumpers correctly.
Unlike the Visual Basic “METER” example, this one uses interrupts.
4.3.5 Oscilloscope — OSSCOPE.EXE
The “Scope” example demonstrates a simple
low frequency two-channel oscilloscope
function with adjustable trigger level.
Depending on computer performance, it can
be configured with a sample frequency of up to
25 kHz on the PC30AT card. It runs on the
PC26AT, PC27E, PC30AT, PCI230 and
PCI260 cards. Care must be taken to set up
any card jumpers correctly.
It requires that the cards be installed with interrupts.
4.3.6 Signal Generator — SIGGEN.EXE
The “Siggen” example is a simple signal generator that
demonstrates sending data buffers to DAC converters
under interrupt control. It can generate sine, square,
triangle and pulse waveforms on up to 4 DAC channels. It
runs on the PC24E, PC25E, PC30AT, PCI224 PCI230
and PCI234 cards. Care must be taken to set up any card
