STM32CubeIDE generates reproducible erroneous code for the STM32L412 Nucleo-64 using ADC1 or ADC2 after a recent update to 1.7.0

[MWest.2]

STM32CubeIDE

Version: 1.7.0

Build: 10852_20210715_0634 (UTC)

In AL_ADC_MspInit an erroneos line is generated after a recent update of STM32CubeIDE and has to be commented out:

PeriphClkInit.AdcClockSelection = ADCCLockSelection;

The following error message is generated

../Core/Src/stm32l4xx_hal_msp.c: In function 'HAL_ADC_MspInit':

../Core/Src/stm32l4xx_hal_msp.c:107:18: error: 'RCC_PeriphCLKInitTypeDef' {aka 'struct <anonymous>'} has no member named 'AdcClockSelection'; did you mean 'I2c1ClockSelection'?

Hello,

I am getting the same error after the latest update. I hope they push a fix soon.

Hi again,

I've had some time to look into this and the STM32L412's ADCs take their clocks from the SYSCLK, so the clock selection would not have any effect (other STM32L4xx can have different ADC clock sources, so they would have a clock mux in there). You can comment out the "PeriphClkInit.AdcClockSelection = ADCCLockSelection;" line and the ADC will still have its clock.

Cheers.

Hi @MMart.20​  & @MWest.2​ ,

This is confirmed to be a limitation in STM32CubeMX 6.3.0.

A complete explanation is provided by @Khouloud OTHMAN​  in this discussion.

I am brand new to STM32Cube and STM32 in general. I've got a NUCLEO-L412KB. I'm running STM32CubeIDE, Version: 1.7.0, Build: 10852_20210715_0634 (UTC). For my first project, I did New, STM32 Project, selected STM32L412KB, and in Pinouts and Configuration, selected ADC1, and clicked Temperature Sensor Channel. I then saved with generate code, and clicked build. It dies on this:

This looks a lot like the error reported in this thread. I really need to use ADC. What's the best fix? Download an earlier version of STM32CubeIDE?

You can just comment out those two lines. There is no clock mux to configure, so the ADC will work.
