Chapter 4: PowerDAQ Software

Each counter is a 24-bit count-up counter, after power-up, the count
value and output of all counters is set to zero. Each counter must be
programmed before it can be used; unused counters need not be
programmed. Counters are programmed by using the PowerDAQ SDK.
Each counter is fully independent of the others except all counters
share the same pre-scaler. Each counter may operate in a different
mode.
PowerDAQ SDK provides a set of examples for the DSP counter/timers.
pdct_evt.c example highlights use of interrupts for the external event
counting. pdct_buf.c example shows, how to use counter/timer stream
mode on the –CT boards. pdsp_uct.c example highlights just a basic
timer programming.
