How to set variable for parameters of assembly macro

Other Parts Discussed in Thread: TMS320F28035, CONTROLSUITE

Hi,

I'm using TMS320F28035 for digit power controller. For module design,I need pack the assembly files by user configuration.One problem be found when calling macro:

PWM_DRV_OUT 1,2,3 1,2,3 are pwm channels.

I want to set variable for parameters of macro PWM_DRV_OUT, calling it as "PWM_DRV_OUT a, b, c ", but errors reported in this code.

I saw some using example like this :

.if a == 1

PWM_DRV_OUT 1,2,3

.else

PWM_DRV_OUT 2,1,3

.endif

Is there any other way to set variable for parameters of macro?

Hi,

Did you try with :

#define func(x,y) ()

assembly is not exactly friendly for passing parameters etc,

we solved it using the method you outlined in an example project in a similar way

C:\ti\controlSUITE\development_kits\BOOSTXL_BUCKCONV\v1_01_00_00\Buck_VMC_F28069M

see the asm file..

Thanks for your suggestion, verify found that C macro with asm(" ") can't recognize the registers struction.

Thanks for you suggestion, verify result as follow:
Seperate PWM_DRV_OUT 1,2,3 to PWM_DRV_OUT_A 1 , PWM_DRV_OUT_B 2 , PWM_DRV_OUT_C 3 ,then use
.if ( a = 1)
PWM_DRV_OUT_A 1
.endif
.if ( a = 2)
PWM_DRV_OUT_A 2
.endif
...
to solute the problem.
