Software Overview

Mono Continuous Mode

The following descriptions explain the software for the data acquisition in Mono
Continuous Mode. The required interface connections are shown in Figure 2

Program Files:

MONOCON1.ASM

Includes the complete software algorithm to control the Mono Continuous Mode

CALIBRAT.ASM

Calibration procedure of the DAC

CONSTANT.ASM

Common file of all modes (constants definition)

VECTORS.ASM

Common file of all modes (IRQ vector table)

Other Files:

linker.cmd

Organization of the DSP memory (data and program memory)

auto.bat

Batch file to start the compiler for the mono continuous software

asm500.exe

C54x Code compiler

lnk500.exe

C54x linker

The timing requirements to interface the ’C54x to the ADC are provided in
Table 11. The STEP numbers given there can be found again as Marker in the
code. This helps to debug and verify the code.

Code verification:

To verify the software, the user must change the code in the MONOCON1.ASM
file and save those changes. The next step is to recompile the four .ASM files by
executing the AUTO.BAT batch file. If compiler and linker finish without error
messages, the new output file is ready to load in the DSP program memory (e.g.
with the GoDSP development tools) and to execute.

The flow chart in Figure 11 gives a general overview of the software structure
(MONOCON1.ASM).
