Unable to map description of pin in CubeMX to datasheet

[Singh.Harjit]

I'm configuring an STM32G474VEH and I right clicked on pin PA3 and I get the attached popup dialog.

The datasheet has OPAMP1_VINM / OPAMP1_VINP / OPAMP5_VINM.

How do these each of these three items map to the entries in the list below?

There is no image attached, and no "list below".

Pins are used by analog peripherals by putting them in analog mode. See:

Sorry the picture didn't come through. Weird - it was in the version I composed. Trying again.

I left click on ball PA3 and this menu pops up (see STM32CubeMX).

Since I'm working with opamp1, what do the following mean:

OPAM1_VINM

OPAM1_VINM0

OPAM1_VINM_SEC

OPAM1_VINP

OPAM1_VINP_SEC

Hello @Singh.Harjit​ 

This will be internally checked.

Thanks

Hi @Singh.Harjit​ ,

Referring to RM 0440 "Table 200.Operational amplifier possible connection", these extra-signals are needed, each according to the chosen mode.

For OPAMPX_VINM_SEC, we just use it if we activate the Timer Controlled Mux mode.

So there's no CubeMX issue, but waiting for DS update.

Best Regards,

Khouloud

A suggestion for the CubeMX team - please make all pin configuration available. For example, in the bit definition for VP_SEL, I can select three inputs VINP0, VINP1 and VINP2 in the registers but CubeMX doesn't let me setup pins for these. I can setup the primary pin and then have to make the pin an GPIO_Analog which is confusing because it would be nice to know which pin i've mapped to which opamp/mux input in CubeMX.
