Hi,
when i use software to trigger ADC1 channel a ,the result in Ra is 0x0804. But, when i use PDB1 to trigger ADC1,the in Ra is changed to 0x0878. Other configuration is all the same. I sample a voltage from 2.5V reference source.
how can i find the problem?
Hi,
There is no reason why it would be different.
I have tested both triggers on ADC1 channel A and the result are identical.

Thank you for you reply!
It has been resolved .the reason is from Self-Calibration mode.
Before, i do like this. Step one, select hardware trigger mode. Step two, run Self-Calibration. Step three, use PDB to trigger ADC1.then Ra is different.
Now, i do like this. Step one, select software trigger mode. Step two, run Self-Calibration. Step three, select hardware trigger mode .Step four, use PDB to trigger ADC1.Then, Ra is identical.
