Where is the rank N°1 settings? (ADC / STM32L151RETx)

[lclor]

I try to set, using last version STM32CubeIDE, the ADC to get 8 analog inputs, using DMA, with permanent conversion.

• I doesn't see anymore the rank 1 ? (see picture)
• When I start HAL_ADC_Start_DMA, i have only the AN0 value, and only 8 bits (I set12bits in parameters), and not refreshed (only one conversion). [HAL_ADC_Start_DMA(&hadc, (uint32_t*)adc_buf, ADC_BUF_LEN);] adc_buf is uint16_t array type.

Best regards,

Hello @lclor​ ,

Thanks for your feedback,

Could you please share a detailed scenario?, What is the CubeIDE version and did you open your project using the same version or did you migrate to a newer version.

Thanks,

Sara.

hello,

All my software and packages are up to date. And I didn't migrate from older version.

I have now again the Rank N°1, I have disabled all INXX, then enable again, and the Rank N°1 is now visible. I couln't give you detail scenario to make the rank N°1 not visible, because I made a lot of tries with ADC settings to try to make it running with DMA.

But I think there is an issue with STM32CubeIDE for this point.

Best regards,

Laurent

Hello @lclor​ ,

Did you by any chance imported a project on your STM32L151RETX using File -> Import Project?

If you didn't could you please share your ioc file to help me investigate more the issue?

Sara.

hello Sara, No, I created the project with CubeIDE. For the IOC file corrupted, I'm not sure that is the right one. /BR Laurent [cid:image001.jpg@01D87722.976A9E50] [Direct]+33 240367483 [cid:image004.jpg@01D87722.976A9E50] [Mail] laurent.clorennec@atauce.com Laurent CLORENNEC [Adresse de courrier]8 Impasse Tournebride 44115 Haute-Goulaine France Ingénieur R&D, Chef de Projet / Electronic Engineering, Project Manager [Web]<> P Please consider the environment before printing.

Hello Sara, Regarding the DMA function apply to ADC, there is an issue in order functions called in main.c : There generating code is : … MX_ADC_Init (); MX_DMA_Init (); … This doesn’t work. I have do that : MX_DMA_Init (); MX_ADC_Init (); And now it’s work.
