Hi !
Temperature measurement in SDk example wakeup only 2 components in PMC:
/* Disable LDOGPADC power down */
POWER_DisablePD(kPDRUNCFG_PD_LDOGPADC);
/* Disable Temperature sensor power down. */
POWER_DisablePD(kPDRUNCFG_PD_TEMPSENS);
Can it be so that we need one more line :
POWER_DisablePD(kPDRUNCFG_PD_GPADC);
Could you suggest right domains for temperature measurement only ?
I should measure temperature only few times per minute and would like to conserve energy as well.
What I should disable for be sure if all components what are involved in temperature measurements are not consume nothing. Or for better stability of temperature sensor I should keep it always ON ?
From other side I have PowerDown mode on sometines and during this mode, almost everything is powerd off automatically.
I assume, I can disable temp sensor all the time and enable it only for few ms when temperature result is really need.

Eugene
Hi, Eugene,
This is the components power down setting register.
But the temperature senor power down bit is reserved in the UM11126.pdf.
I think you should not power down the temperature sensor if you use it, because the temperature takes time to have the have temperature voltage stable.

Hi xiangjun.rong !
So I shouldn't powerdown temperature sensor, but I can powerdown ADC and LDO ADC.
Is this so ?
Regards.

Hi, Eugene,
Yes, You shouldn't powerdown temperature sensor, but you can powerdown ADC and LDO ADC.
