FILE: readme.txt Copyright (c), Symmetric Research, 2003-2004 Meter is a sample program collecting meter like values from one of the PARxCH 24 bit A/D boards. The program collects data as soon as it is ready from the board. In order to achieved a slow sampling rate while still maintaining good resolution, meter samples at an actual rate of 50Hz and averages 50 successive samples to achieve an effective 1Hz sampling rate. Optionally the program can display counts or volts. The volts display involves a conversion that must be calibrated. Refer to the source code comments for more details. Once the system is powered up and running, simply run meter from the command line and data will appear from all analog channels at a 1Hz rate. If you have any trouble getting the program to start, run the standard diagnostic program in the diags directory to determine which parallel port modes your PC supports. You can then run meter again including a supported mode on the command line as the optional second argument. If you need to change the parallel port address, you must edit and then recompile meter.c. See the makefile for how to build it.Download Driver Pack
