Hello, I'm learning about the UCD3138's hard-switched full-bridge firmware.
I have some problems with void init_loop_mux(void){}.
Void init_loop_mux(void)
{
LoopMuxRegs.DPWMMUX.bit.DPWM0_SYNC_FET_SEL = 2; /
LoopMuxRegs.DPWMMUX.bit.DPWM1_SYNC_FET_SEL = 2
FeCtrl2Regs.RAMPCYCLE.bit.SWITCH_CYC_PER_STEP = 1;//
FeCtrl2Regs.RAMPCTRL.bit.SYNC_FET_EN = 1; //
FeCtrl2Regs.RAMPCTRL.bit.RAMP_EN = 1; //
FeCtrl2Regs.RAMPCTRL.bit.SYNC_FET_RAMP_START = 0; //
FeCtrl2Regs.RAMPDACEND.bit.RAMP_DAC_VALUE = 1100; //
FeCtrl2Regs.DACSTEP.bit.DAC_STEP = 10;
}
I know this program is to configure the RAMP function of DPWM0B and DPWM1B.
I don't know if I understand it right?
RAMP is increased from 0, one step per 2 switching cycles, each step is 10, and after 220 cycles, RAMP is increased to the final value of 1100.
I still have a question, that is why the final value of RAMP is 1100. How is this 1100 obtained?
