But the conversion result thet obtained is influenced by the result conversion.
What was it caused?
There are two cases.
(1) It is caused by Hardware.
- Please lower the impedance of the signal source
Refer to the following chart for an example.
(2) It is caused by Software.
It causes by bad read-out timing the data of the conversion result.
Refer to the following for a program.
 Clear ADCS bit and stop A/D conversion operation
 Set ADMK bit and prohibit A/D interruption.
(During interrupt function execution, it is needless to prohibit)
 Clear ADIF bit.
 Switch the input by ADS register.
 Clear ADMK bit, and enable A/D interruption.
(During interrupt function execution it is needless to prohibit )
 Set up ADCS bit, and start to convert.
 Read-out the conversion data with A/D interruption.
We convert in order of the above.
If you can't solve the problem by the methods mentioned above, please lengthen the time interval of each A/D conversion.
