Hello, for a STM32F474RBT device, STM32CubeMX V.5.4.0 with Firmware V.1.1.0 allows to put OPAMP1_INP and COMP1_INP on a single port PA1. Is this really a valid configuration, or is it a CubeMX bug?

[Andrea Canepa]

It is not a BUG. Both in F3 and in G4 it is possible to use the same analog input pin for more analog peripheral.

This can help to reduce the number of pins. You can use the MCU manual to see which pins have matched that particular analog peripheral.

Thank you very much! I had some trouble with CubeMX 5.4 configuring a STM32F334, ended up with going back to version 5.3...
