Hi,
I have stucked trying to use hrtim pwm outputs on stm32f334r8.
I use initialisation provided by CubeMX to start all 10 channels right now. I use exactly the same setting for every channel, but still have different results.
It is not possible to fit init code here, but here the main parts:
//TIMER CONFIG START
pTimeBaseCfg.Period = 0x0960;
pTimeBaseCfg.RepetitionCounter = 0x00;
pTimeBaseCfg.PrescalerRatio = HRTIM_PRESCALERRATIO_DIV1;
pTimeBaseCfg.Mode = HRTIM_MODE_CONTINUOUS;
//WAVEFORM TIMER CONFIG START
pTimerCfg.InterruptRequests = HRTIM_TIM_IT_NONE;
pTimerCfg.DMARequests = HRTIM_TIM_DMA_NONE;
pTimerCfg.DMASrcAddress = 0x0000;
pTimerCfg.DMADstAddress = 0x0000;
pTimerCfg.DMASize = 0x1;
pTimerCfg.PushPull = HRTIM_TIMPUSHPULLMODE_DISABLED;
pTimerCfg.FaultEnable = HRTIM_TIMFAULTENABLE_NONE;
pTimerCfg.FaultLock = HRTIM_TIMFAULTLOCK_READWRITE;
pTimerCfg.DeadTimeInsertion = HRTIM_TIMDEADTIMEINSERTION_ENABLED;
pTimerCfg.DelayedProtectionMode = HRTIM_TIMER_A_B_C_DELAYEDPROTECTION_DISABLED;
pTimerCfg.UpdateTrigger = HRTIM_TIMUPDATETRIGGER_NONE;
pTimerCfg.ResetTrigger = HRTIM_TIMRESETTRIGGER_NONE;
pTimerCfg.ResetUpdate = HRTIM_TIMUPDATEONRESET_DISABLED;
//COMPARE CONFIG START
pCompareCfg.CompareValue = 0x04b0;
//DEADTIME CONFIG START
pDeadTimeCfg.Prescaler = HRTIM_TIMDEADTIME_PRESCALERRATIO_DIV1;
pDeadTimeCfg.RisingValue = 0x050;
pDeadTimeCfg.RisingSign = HRTIM_TIMDEADTIME_RISINGSIGN_POSITIVE;
pDeadTimeCfg.RisingLock = HRTIM_TIMDEADTIME_RISINGLOCK_WRITE;
pDeadTimeCfg.RisingSignLock = HRTIM_TIMDEADTIME_RISINGSIGNLOCK_WRITE;
pDeadTimeCfg.FallingValue = 0x050;
pDeadTimeCfg.FallingSign = HRTIM_TIMDEADTIME_FALLINGSIGN_POSITIVE;
pDeadTimeCfg.FallingLock = HRTIM_TIMDEADTIME_FALLINGLOCK_WRITE;
pDeadTimeCfg.FallingSignLock = HRTIM_TIMDEADTIME_FALLINGSIGNLOCK_WRITE;
//OUTPUTS CONFIG START
pOutputCfg.Polarity = HRTIM_OUTPUTPOLARITY_HIGH;
pOutputCfg.SetSource = HRTIM_OUTPUTSET_TIMPER; //doesn't work with res
pOutputCfg.ResetSource = HRTIM_OUTPUTRESET_TIMCMP1;
pOutputCfg.IdleMode = HRTIM_OUTPUTIDLEMODE_NONE;
pOutputCfg.IdleLevel = HRTIM_OUTPUTIDLELEVEL_INACTIVE;
pOutputCfg.FaultLevel = HRTIM_OUTPUTFAULTLEVEL_NONE;
pOutputCfg.ChopperModeEnable = HRTIM_OUTPUTCHOPPERMODE_DISABLED;
pOutputCfg.BurstModeEntryDelayed = HRTIM_OUTPUTBURSTMODEENTRY_REGULAR;
You can see the result on the images. Outputs A and E works great. Output B doesn't work at all. C has strange mistake - both outputs are the same, not opposite. C also has some problems with PWM, because of deadtime. D has same problems with pulses.
So the main question is simple as usual - what am i doing wrong here?)
UPD: Found another strange thing:
if I run all the timers, but start only pwm generation on A,D,E - I got nothing on TD1 while TD2 is working.
