Compiler/TMS320F28069: PWM #define MACRO Functions

Part Number: TMS320F28069

Tool/software: TI C/C++ Compiler

Hello

I made two macro function to manage pwm trip zone

First macro works ..

#define PWM_1_TZ_ON(){EALLOW;                           \
               EPwm1Regs.TZCLR.bit.OST             = 1;\
               EPwm1Regs.TZEINT.bit.OST            = 1;\
               GpioDataRegs.GPADAT.bit.GPIO19 = 1;\
               Inverter.Status.BITS.BuckHT             = 1;\
               EDIS;}

Second macro doesn't work

#define PWM_3_4_ON(){EALLOW;                  \
               GpioDataRegs.GPADAT.bit.GPIO22    = 0;\
               EPwm3Regs.TZCLR.bit.OST                = 1;\
               EPwm4Regs.TZCLR.bit.OST                = 1;\
               EDIS;}

I am obliged to place a breakpoint just before macro function and then it works ?!:?$*?

Somebody has got an idea why it does that ?

Can you elaborate what you mean by "doesn't work"? What part of the macro fails?

Macro is doesn't took into account and seems to jump to other part of prog

Hello,

I don't think there's anything wrong with the macro itself. You could look at the disassembly if you wanted to make sure it was getting inserted correctly though.

If you put a delay in the code before the second macro, does it have the same effect as the breakpoint? I'm wondering if it's the delay that the breakpoint provides that's actually causing the code to work.

Whitney , how to see assembly code in CCS6 in the past we have disassembly on/off on CCS3 but I didn't find it on CCS6 ?

When you're debugging you can go to View->Disassembly to step through the instructions as they're executing.

If you just want the generated assembly to be saved to a file when you run the compiler, you can right click a project, go to Properties window and look under Build->C2000 Compiler->Advanced Options->Assembler Options for a --keep_asm option.

Hi OL,

Did you ever find out what the problem was?

Hi Whitney,

No I didn't find solution !

I still be with the problem I must place a breakpoint to have the expected comportment otherwise it goes through without taking into account macro code instruction (except if I performed step by step sequence). I don't understood why. I tried to insert macro codes lines directly in the code, it is the same behavior....

I you have any idea it is really welcome !

Did you ever try my suggestion above about adding a delay?

If you put a delay in the code before the second macro, does it have the same effect as the breakpoint? I'm wondering if it's the delay that the breakpoint provides that's actually causing the code to work.

Thanks,

Whitney
