Programming the ezDSP USBstick with pure assembly language only using CCS4

Nettech

Has anyone ever successfully been able to write DSP code using only assembler mnemonics in CCS4?

Take the EZDSP_Sample project, for instance.

I tried adding opcodes to vector.asm (after the init code finishes and b4 it drops into the C-Int routine) but I get a parse error for any opcode I use.

The .asm files seem to only accept some type of macro language (for example, bit(ST3,#7) = #0 ; Clear bus error interrupts).

Does anyone have an example project that will actually compile C5505 assembly language?

Thanks!!

Hi Nettech,

vector.asm is programmed in algebraic assembly, while you are referring to mnemonic assembly. You can specify in which assembly language you want to program under Properties -> C5500 Compile -> Runtime Model Options -> Select Assembly Source Language. I believe you cannot mix these two languages.

Cheers and regards,

Michael
