RTOS/CC1312R: ADC Read interval

Your post does not contain enough information to fully answer your question.
- You write that you read temperature with the ADC. What is the input to the ADC?
- You write that you are not reading the correct temp value. What do you read when it's incorrect and what do you read when it's correct?

answer 1 : The input of the ADC is the value of the temperature sensor as seen in the schematic.
answer 2 : The current temperature is measured through the electronic thermometer.
The correct value was the same as the value of the electronic thermometer.
The incorrect value produces a strange value that is very different from the temperature value.

<Detail explanation about project>
1.The circuit configuration consists of [ADC Enable Pin] to reduce current consumption and [ADC Pin] to read Temp sensor.

                

2.The operation of the project is basically Standby mode and wake up every 5 seconds through the clock instance.
3.Detailed operation is as follows.
(1).Call temp sensor event from clock callback function.
     (Event_post(nodeEventHandle, NODE_EVENT_CHECK_SENSOR);)
(2).Set [ADC enable Pin] to HIGH.
      (PIN_setOutputValue(pinEnableHandle, ENABLE_ADC, HIGH))
(3).Delays 10ms
      (Task_sleep(TIME_MS(10));)
(4).Use ADC_Convert to read the ADC value of the temperature sensor.
     (res1 = ADC_convert(adcTemp1Handle, &adcValue);)

To reduce current consumption, I remove Task_sleep(TIME_MS(10)).
However, when reading the ADC value, the correct temperature value could not be read.

1.Do I need a delay to read the correct ADC? ( Is there an ADC document about delay? (about correct adc read))

2.If I do not have problems with software, do I need to modify it circuit?

Thanks.

I removed 100 nF Cap and the normal ADC value is read. Thanks.
