SCT0 peripheral generated code wrong?

[cedricjehasse]

When configuring SCT0 in the peripherals, i think the generated code is wrong when selecting `Start L/unified counter`

This adds the following line to the generated SCT0_init function:

  SCTIMER_StartTimer(SCT0_PERIPHERAL, kSCTIMER_Counter_L);

this doesn't work, there's no pwm output. If i change kSCTIMER_Counter_L to kSCTIMER_Counter_U, it does work.

config tools version is 11.0 and  the MCU is a LPC54005JBD100

thanks,

Cedric

Hi Cedric,

you're right, thanks for bug report, it will be corrected in the next version.

Hi,

I'm not sure where is the problem in this case, however, could you write more about your goal with SCTimer?

If it's more than just very simple PWM, I recommend to use the SCTimer register init component that allows to leverage all capabilities of the hardware and it's not dependent on SDK driver. 

To add this component you can use the Components view and clock on the '+' button at Register initialization category:

Hi,

our goal is to have a simple pwm.

For us the issue is fixed by manually starting the timer like this isof the generated code:

SCTIMER_StartTimer(SCT0_PERIPHERAL, kSCTIMER_Counter_U);

Just wanted to report this in case someone else runs into it.

Thanks for the suggestion on register init. I'll have a look if we ever need more advanced pwm.

Best regards,

Cedric
