ADC not working on STMduino example

[beaka]

One last try to try to get some coherent and helpful assistance about the ADC problem on Weact G474 using Arduino IDE.
Using the ADC Internal example just gives 0's or an arbitrary value.
Simple analogread on any analog pin just gives 0's.

Using Arduino 2.3.6 from flatpak with STM MCU 2.10.1. for a Weact STM32G474CE Long board. There is NO PC0 analog pin.

Any actual advice rather than blanket dismissal would be appreciated.

Any further information can be provided if asked for.

Hi @beaka

One last try to try to get some coherent and helpful assistance about the ADC problem on Weact G474 using Arduino IDE.

You claim to get coherent and helpful assistance but all issues or discussions you raised are only to told it's not working without any detail of you environment, configuration... Moreover several time it was build issue which is not possible with the standard configuration.
How would you like to answer this kind of request?

As stated before it works and again don't know why not on your side. Your best bet is to try to debug to understand why.
If you always get 0 this means analogRead get an error as it is the default value return in this case.
Hardware broken? Did you test only with one board? Wrong usage of the board?

There is NO PC0 analog pin.

Why you point this? STM32G474CE has no PC0 pin so indeed there is no PC0 analog pin...

OK, I have posted amny times with enough info for you to either determine an answer or ask for more specific info. To address your points/questions/criticisms. I purchased 4 boards from Weact store on Aliexpress. All behave the same way. Have you actually tested on one of those boards not a nucleo which is why I point out the PC0. I plug the board into the USB port of the computer and setup the Arduino IDE as shown in the pictures, how else can I do it. How am I doing it wrong? As stated on previous assistance requests, the same code previously worked on a Weact 401CC board but not on the G474. I noted also on different code in inclusion od a .h file broke the compilation of your libraires to which you just responded it can't, but I showed you it did. So stop with the blanket, it works, and help me find out why I wasted my money on ST products.

It seems we do not have the same understanding.
I've tested with a Weact G474CE and it works.
Again why talking about PC0 while STM32G474CE has no PC0. That only bring confusion.

I noted also on different code in inclusion od a .h file broke the compilation of your libraires to which you just responded it can't, but I showed you it did.

Did you see this?

So sorry if my answer do not satisfied you but honestly I'm not a magician and guess what user do and what they used (hardware or third party software).

So stop with the blanket, it works, and help me find out why I wasted my money on ST products.

Which blanket? it works that's all. Note that it is not fully a ST product. Only the mcu if it is not a fake.
Are you sure it is a guenine STM32G474CE? Are you sure it is not a bad batch and all your boards are broken?

The analog part of the core is tested daily on several STM32 series and mature since several years.
So, what can I do except told you it works. And that you have to understand with your configuration, with your hardware why it does not work? Simply launch a debug session. I can't do it for you.

Hardware issue.

[beaka]

Well, it was software after all. Got it working now. All the boards work and it was your software after all.

[fpistm]

Fine, so what do you do to have it working?

[beaka]

The issue has been resolved. you said so yourself. Even though I had to fix it. It was not hardware it was the stm32duino package.

Anyway, it would be fine you share with the community what was your issue and how you resolve it.
Could I assume, that when you told it's stm32duino package, there was a mistake during install?

[beaka]

No on both points. You cost me a lot of time and were condescending at best. I am not paid to do your job.

Fortunately not.
To close this topic, I think you simply made mistake and you don't want admit it.
It's always a pleasure to help this kind of user with such bad faith. Fortunately, they are very rare.
Bye.
