Part Number: UCD3138HSFBEVM-029
Tool/software: Code Composer Studio
I am using UCD3138HSFBEVM, i have refereed some videos in ti website, first thing is i have to write code for obtaing dpwm signals, i have attached code below.
I am not getting DPWM signal could you please tell me where am i going wrong?
#define MAIN 1
#define PCLK_PERIOD 4.0e-9
#define PERIOD_SECONDS 10.0e-6
#define PERIOD_CLK ((int)(PERIOD_SECONDS/PCLK_PERIOD)<<4)
#define EVENT1 (int)(PERIOD_CLK*0.00)
Dpwm0Regs.DPWMCTRL0.bit.PWM_MODE = 0; // Set to normal mode
Dpwm0Regs.DPWMCTRL0.bit.CLA_EN = 0;
Dpwm0Regs.DPWMPRD.all = PERIOD;
Dpwm0Regs.DPWMEV1.all = EVENT1;
Dpwm0Regs.DPWMCTRL0.bit.PWM_EN = 1;
LoopMuxRegs.GLBEN.bit.DPWM0_EN = 1;
if(GioRegs.FAULTIN.bit.FLT3_IN == 0)// Re-Check pin assignment (ADC_EXT/SYNC may be?)
MiscAnalogRegs.CLKTRIM.bit.HFO_LN_FILTER_EN = 0;
MiscAnalogRegs.CSTRIM.bit.RESISTOR_TRIM =23; //28;
ram_event2 = Dpwm0Regs.DPWMEV2.all;
Dpwm0Regs.DPWMEV2.all = ram_event2;
I don't see anything obviously wrong with it, except that you are calling init_dpwm0, and the function is called init_dpwm.
But I'm not a compiler or a UCD3138, so I'm not a very good judge.
Whenever I have to get a DPWM going, I start with an existing code, in this case, probably the lab codes which go with the videos, and change it from there, as quickly as I dare, which is often not very quickly, especially if the quick change doesn't work the first time.
That's the course I'd suggest for you.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
