Software Overview

8.5.6C-Callable with Mono Interrupt Driven Mode Using CSTART to Start Conversion

The following descriptions explain the software for the data acquisition with a user friendly C program interface in monomode using the CSTART signal. The required interface connections are shown in Figure 2.

Program Files:

C1562.ASM	Includes the complete software in the C-layer
asm1562.ASM	Includes the complete software algorithm to control the monomode
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 monomode software
C1500.exe	Compiler c-code into assembler
mnem2alg.exe	Mnemonic – algebraic instruction converter
asm500.exe	C54x Code compiler
lnk500.exe	C54x linker
rts.lib	Library to organize boot loader

The timing requirements for interfacing the ’C54x to the ADC are provided in Table 13. The STEP numbers given there can be found again as Marker in the code. This helps to debug and verify the code.

Code verification:

The user only needs to edit the C1562.C – software file and to run the AUTO.BAT to adapt the acquisition. This software samples one of the four channels, with a specified number of samples, and stores each sample into a defined memory location.

To verify the software, the user must change the code in the C1562.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.
