Summaries of the finished applications are shown below. See the PDF user manual for more details. Software is available for Windows and Linux. The most recent software and manual are available for free from the SER1CH-UA section of our Legacy Downloads page.
Finished Applications:
DVM
This is a digital volt meter program in two versions. DvmGui provides a Windows GUI interface while DvmCmd is text only. Both display acquired values as voltages or other scaled user units like inches. Data is displayed as it becomes available, and is also written to an output file. An initialization file is used to specify calibration and display units. For convenience, two different unit scalings are displayed on the screen for the single SER1CH-UA channel.
CAL
This calibration program is a companion for DVM. CalGui is the Windows GUI version and CalCmd is text only. Both compute the calibration values needed to convert A/D counts into scaled user units. The calibration information is saved in a DVM initialization file.

SIMP24B
This is a simple 'text only' acquisition program. Acquisition parameters such as sampling rate, gain, and output file size are specified in ASCII form in an initialization file. Acquired data can be presented on the screen as text values and saved to the hard disk in binary multiplexed format. This program is perfect for applications where the acquisition will run unattended or for lower power PCs where a complicated GUI interface would be excessive.
SCOPE24B.EXE
This is a full Windows GUI interface program that displays acquired data as horizontal traces on the screen. Acquired data is scrolled across the screen as it comes in and is also saved to disk. All acquisition parameters, such as sampling rate, gain, and output file size, are set by dialogs reached from pull down menus. Hot keys like up and down arrow can be used to adjust the number of displayed bits for the signal level you are using. The binary file format is exactly the same as for simp24b.
METER
This is a simple text only program that displays acquired values as voltages on the screen. Data is presented the instant it becomes available as it would be with a typical DVM. The program includes individual channel calibration.
DIAG
The system diagnostic can be used after installation or any other time to verify that the A/D board is correctly connected and communicating with the PC. This utility can prove very valuable in the field when connecting new hardware.
TWO TASK SUPPORT
Under multitasking systems like Windows and Linux you can run acquisition as one task while a second task examines the acquired data files and performs further processing. Typical second window activities might include items like triggering accept/reject decisions on files so an excessive amount of data does not build up on the hard disk. The 2task example included with the system shows how to run a simple threshold trigger. Under Windows, each task typically runs in its own window. Under Linux, the acquisition task usually runs in the background while the processing task runs in the foreground.
LABVIEW SUPPORT
LabVIEW drivers and finished applications paralleling the other software are provided. The applications are a finished scope acquisition and LED meter display program. These programs are 'ready to go' and do not require any user programming, but you must have a copy of LabVIEW in order to use them. Full LabVIEW 'G' source code is provided.
LIBRARY SUPPORT
Basic driver support is provided as a collection of library functions that let you initialize, start acquisition, and copy results to the PC. The library source code can be compiled to either static or DLL (shared library) format with no changes and is written in standard ASCII C. See below for a list of functions.
| PAR24B_Init | Initializes PAR24B w/ sample rate, gain, etc |
| PAR24B_Start | Begins PAR24B acquisition |

DSPASM.EXE
The DSPASM assembler is designed to process source files with Agere mnemonics and high level control constructs to produce located object files that can be directly downloaded and executed on the coprocessor board. It is ideal for code development requiring fast edit and execute cycles. Some of the features of DSPASM are: free format source code, symbolic register names, nops emitted for CAU but not DAU instructions, forward references, and C like conditional syntax including if, while, and for loops.
DSPMON.EXE
The DSPMON program is a software tool for monitoring and controlling the DSP32C coprocessor boards by hand. Its commands are quite similar to those of debug or symdeb for the 80x86 on the PC, and users familiar with those programs should find DSPMON easy to use. Using DSPMON is a good way to get familiar with the coprocessor board. No damage can occur from anything done within DSPMON.
DSPTOOLS SYSTEM UTILITIES LIBRARY
The DSPTOOLS system utilities library is a collection of functions for controlling the execution of the DSP32C coprocessor boards from C programs running on the PC. With it, you can upload and download the DSP32C boards from programs you write. In fact, the DSPMON monitor is an example of a program that makes use of these functions, where each operation allowed in the monitor corresponds to a function call in the DSPTOOLS library. See DSPTOOLS functions below for a list of functions.
DSPMATH MATH LIBRARY
The DSPMATH library is a collection of math functions for the DSP32C coprocessor boards. With this library, functions can be called from high level languages without having to program the board directly. It is one of the easiest ways to begin getting results from the DSP32C boards. See DSPMATH functions below for a list of functions.
