在本文的第 32 页，图 38 显示了双电机控制应用的概述。
其中 OPAMP2 通过内部多路复用器连接到 ADC2IN16，
它还输出到外部引脚 PA6，该引脚通过附加线路连接到 ADC1IN1/PA0。
Translation:
"On page 32 of this article, Figure 38 shows an overview of a dual motor control application.
Where OPAMP2 is connected to ADC2IN16 via an internal multiplexer,
it also outputs to external pin PA6, which is connected to ADC1IN1/PA0 via additional lines."
但是，我无法理解这是如何完成的，我也无法在 CUBEMX 中配置它。
第 10 页的图 12 描述了多路复用器的功能，
它不能同时向 ADC 和外部引脚输出信号。
谢谢。
Translation:
"However, I cannot understand how this is done, and I cannot configure it in CUBEMX.
Figure 12 on page 10 describes the function of the multiplexer,
It cannot output a signal to both the ADC and an external pin at the same time.
Thank you."

Hello Hakuki_Riumiya,
There is a mistake in the Figure 38. The input to ADC2 must be taken from PA6 pin and not from the internal OPAMP2 output.
Correct schematic is like this:
In CubeMX : it is possible to configure this correction like described above - but you must enable "Pin Stacking" on the PA6 pin (right clock on PA6 pin) - to be able to connect multiple functions on PA6 (ADC2_IN3 + OPAMP2_VOUT):
Regards
Igor
