Software Overview
8.5.5Dual Continuous Mode
The following descriptions explain the software for data acquisition in dual continuous mode. The required interface connections are shown in Figure 2.
Program Files:
DUALCON1.ASM | Includes the complete software algorithm to control the Dual 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 dual 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 12. 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 DUALCON1.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 12 gives a general overview of the software structure (DUALCON1.ASM).
