STM32CubeMX Bug: NbrOfDiscConversion not set

When Discontinuous Conversion Mode is disabled CubeMX leaves the NbrOfDiscConversion field in ADC_InitTypeDef uninitialized which can cause assert_param(IS_ADC_REGULAR_NB_CONV(hadc->Init.NbrOfConversion)) in

HAL_ADC_Init to trigger resulting in an assert failure.

CubeMx Version 4.9.0

STM32Cube FW_L1 V1.3.0

Dear user,

thank you for reporting this issue.

Actually, the parameter

NbrOfDiscConversion

shall not be initialized when Discontinuous conversion is disabled.

The ADC HAL driver will be corrected so that the following line is executed only if Discontinuous conversion is enabled:

assert_param(IS_ADC_REGULAR_DISCONT_NUMBER(hadc->Init.NbrOfDiscConversion));

Best regards

Dear user,

The fix will be delivered within STM32L1 1.4.0 package supported in our next CubeMX version 4.11 (coming out this month).

Thanks.
