H7 ADC3 does no longer offer selection for temperature after update to IDE 1.15

[kdh]

Hi there,

after updating to STM32CubeIDE 1.15.0 with H7 Package 1.11.1 H7 ADC3 does no longer offer selection for Temperature Reference, VBat and Vrefint Channels. Screenshot was made with V1.14, missing selections are marked : - ]

 

Best regards, kdh

Hi,

I will check internally and get back to you with a feedback. Thanks

hello,

i am seeing the same thing

thanks

Sorry for the confusion, it is now "hidden" behind the respective ADC channel. You'll find it e.g. for the STM32H723 behind a selection of IN17. Pleae check the reference manual for your device to find the correct ADC channel.

[edit] I was too quick - my statement is true for ADC2, IN17. It is (currently) not true for the VBAT channel, which should be available via ADC2, IN16, but there is no IN16 visible [/edit]

Hope that helps?

Regards

OK, explicitly I'm talking about H743ZG - you might win a price if you show me where to find chanells with higher number than 11 in IOC - regards, kdh

Hi @Peter BENSCH ,

this is what the manual of the H723 shows:

There are no channels 16, 17 and 18 for ADC3. Why is there an option for vrefint at ADC2, I can't find this connection in the manual.

Best regards

Jens

@JensH agree, there is something misleading. Fig. 163 is showing

• VBAT/4 connected alternatively to ADC2, VINP[16]
• VREFINT connected alternatively to ADC2, VINP[17]

and the footnotes at table 223 mention:

1. ADC2 VINP[17] alternate connection can be switched though SYSCFG_ADC2ALT register (section 12.4.10).
2. ADC2 VINP[16] alternate connection can be switched though SYSCFG_ADC2ALT register.

Essentially the same problem as there.

Hello @kdh 

The internal ticket 176638 (not accessible by the community users) has been created to confirm/fix the issue.

Seems to be a regression in v6.11 of CubeMx vs V6.10.
I'll keep you informed by any feedback.
Thank you for your contribution.

Hi,

Same problem here, using a Nucleo-H745ZI-Q.

I don't know if it helps you guys, but here is the diff that was applied to my IOC file. It does not allow me to generate code.

Regards,

Marcelo.

I am running at STM32H747 with the exact same issue. Has anyone got a work-around until there is an official ST update to re-instate these settings?

Thanks

Hello All,

This issue is fixed in the latest patch release of STM32CubeMX v6.11.1.

Thank you for your contribution and for your patience while we worked on this.

Hi Imen,

I have seen, that the new version 1.15.1 offers the ADC3 selection for temperature, vref an vbat again.

Thanks for the repair.

But I have to mention that I had to reinstall the offline repository for the H7. Without this installation, my CubeIDE crashed completely and I had to restart the whole PC.

Best regards

Jens

1.15.1 get me further than 1.15.0, but i am now encountering the problem reported here:
