ADS2184 trouble with VisualDSP++ and variable declaration

Some time has past since I programmed the ADSP2184 and now I have to
deal with VisulDSP++ 3.5 and LDF files. I tried to declare variables
in my assembler program like:

.section/data port_data;
.var adc_1;
.var dac_1;

.section/data data1;
.var ch_sum;

.section/data data2;
.var table_2[3];

etc....

In the good "old" days it worked fine. Now everything compiles fine
too but it doesn't work in the target hardware (simulation works). I
have also found no good way to declare the ports in the ldf files.
Is there anybody out there who had a similar problem and is still
programming stuff in assembler. I would very much appreciate any
comments and help.

Thanks,

Hi Stephan,

I think you are referring to the .ach files in the 'good old days' ;-)

I'm a bit rusty with 218x, but this should work.

You would not have to declare ports in the ldf. You could just have
something like

#define adc_1

dmovlay = 1 (or 2);
ax0 = DM(adc_1);

Assuming it is memory mapped in DM, rather than PM or IO spaces.

Cheers,

George
