Nucelo STM32H563ZIT6: Internal temperature sensor issue

[Subhashzimetrics]

Hi Support team,

I am working on STM32H563 Nucleo project and trying to integrate internal temperature sensor.

I enabled internal temperature sensor channel available at ADC1, but getting crash while executing below conversion code:

TS_CAL1 = *TS_CAL1_ADDR;

PFA project for reference.

Please help in resolving the issue.

Thanks.

What, exactly, do you mean by "getting crash" ?

If it's a Hard Fault, see Tips on debugging Cortex-M Hard Faults.

 

BTW: Although it doesn't really matter for just a single line like that, please see How to insert source code for putting source code in a post.

Hello,

I suspect you have an issue as described in this knowledge base article: How to avoid a HardFault when ICACHE is enabled on the STM32H5 series 

PS: your project hasn't been uploaded.

It seems to be stuck on "virus scan in progress..." - I've raised this in the Feedback Forum.

It was like that when I made my 1st reply - which is 3 hours ago now.

I think I've also seen other posts like that today...

Exact and I reported that internally.

Hi @Andrew Neil ,

Sorry for delayed reply from my end.

We followed project attached in below related post on:

https://community.st.com/t5/stm32-mcus-products/stm32h5-inconsistent-internal-temperature-measurement-using-adc/m-p/857049#M288942

Since this post is for same STM32H563 mcu, so attached project (H5_Internal_Temp.zip) should have worked for us straight. But we are getting Hard fault to access this OTP area.

Though we are able to read ADC channel data from internal temperature sensor,  we dont' know how to convert that data to actual temperature value.

Pls help to resolve the issue.

attaching my project again

 

thanks,

Subhash

Did you read my previous post:

PS: Unfortunately there is an issue regarding the attachments these days. Infinite "Virus scanning in progress" .. reported here.

Hi, 
Thanks for your support. i am able to get temperature after mpu config. it is not calibrate 
Please help to calibrate the temperature.

That's a new question. Please ask that question separately.

Thank you for your understanding
