It allows the available timer resources to be programmed in a variety of modes (rate, single shot
etc.) and frequencies.
It does not use interrupts.
4.2.3 Frequency Multiplier — FREQMULT.EXE
The “Frequency Multiplier” example demonstrates using the TCmultiplyFreq function on Series 200
Digital IO Cards. It runs on the PC212E, PC214E, PC215E, PC218E and PCI215 digital counter
timer cards.
It measures a frequency using one set of timer channels and produces a multiplied version of that
frequency on another.
It does not use interrupts
4.2.4 Event Recorder — EVENTREC.EXE
The “Event Recorder” example demonstrates the use of the “TCsetEventRecorder” function on
Series 200 Digital IO Cards. It runs on the PC212E, PC214E, PC215E, PCI215 and PCI230.
It starts a millisecond timer and records when PPI X Bit C3 interrupt occurs.
It requires that the cards be installed with interrupts.
4.2.5 Digital IO With Interrupts — DIO_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 requires that the cards be installed with interrupts.
Versions of this example supplied with AMPDIO v4.31 or earlier cannot be compiled and run under
Visual Basic 6.0.
4.2.6 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.
It does not use interrupts.
Versions of this example supplied with AMPDIO v4.31 and
earlier required the card to be installed with interrupts.
Because of the style of user interrupt set-up functions used,
these versions could not be compiled and run under Visual
Basic 6.0.
