8 Software Overview
The software in this report shows how to use all modes of the TLV1562 and useful
variations for each mode. It also includes a C program to start data acquisition
from a C level. To limit the number of programs, the report supplies five files for
running the ADC in five modes; a sixth program shows the C-callable function.
Each program can enable different software blocks to give the user a large choice
for generating the data acquisition. For more details, see paragraph 8.3.9.
Instead of using numbers for memory addresses or constants, very often
symbols replace the numbers. For that, the symbol (name) is assigned with the
real value (number) in the file header. The advantage of doing this is the higher
flexibility. Instead of changing a variable memory location in every related
instruction, the value for this location is changed only once in the program header.
This prevents software bugs from appearing through a forgotten correction of a
related instruction.

@AXR = #(BSPC_BUFFER_START) ; assign the starting address of auto

8.1 Software Development tools
The DSKplus Starter Kit of the TMS320C54x comes with a free compiler to
generate an absolute object file from assembler code (DSKPLASM.EXE in the
TMS320C54x DSKplus development tools). The object code is then loaded into
the GoDSP software to run it on the kit.
An advanced version of this kit is the TMS320C54x Optimizing C Compiler/
Assembler/Linker (for example: TMDS324L855-02). These tools allow
generation of object code from C and assembler files. Furthermore, they also link
the code to an executable COFF file. The software in this report was created with
these tools.
