Here is the translation of your post using Google translate:
In the ADC of STM32F401, what is the relationship between discontinuous mode and scan mode,
The Scan mode is used to scan a group of analog channels. A single conversion is performed for each channel of the group. After each end of conversion, the next channel in the group is converted automatically.
Discontinuous mode has two groups:
- Regular group: This mode can be used to convert a short sequence of n conversions (n ≤ 8) that is part of the sequence of conversions selected in the ADC_SQRx registers.
- Injected group: It can be used to convert the sequence selected in the ADC_JSQR register, channel by channel, after an external trigger event.
For more explanation I advise you to refer to RM0368 and precisely section 11.3 ADC function description.
