CubeMX generates wrong ADC code for F0 family when using Vrefint or Temperature channels

Steps to reproduce:

1) Create new project, select STM32F030C8Tx chip

2) In Peripherials enable Vrefint Channel for ADC

3) Click Configuration -> ADC, optionally configure ADC parameters, note that in the channel config Rank is preset to

1

and cannot be changed

4) Generate code

Following code will be generated to configure channel:

/**Configure for the selected ADC regular channel to be converted.

*/

sConfig.Channel = ADC_CHANNEL_VREFINT;

sConfig.Rank = 1;

sConfig.SamplingTime = ADC_SAMPLETIME_1CYCLE_5;

HAL_ADC_ConfigChannel(&hadc, &sConfig);

It will fail

IS_ADC_RANK

assert in

HAL_ADC_ConfigChannel

because provided Rank value is

1

, and macro accepts only

ADC_RANK_NONE

or

ADC_RANK_CHANNEL_NUMBER

values:

#define IS_ADC_RANK(WATCHDOG) (((WATCHDOG) == ADC_RANK_CHANNEL_NUMBER) || \

((WATCHDOG) == ADC_RANK_NONE)

Hello,

This will be fixed in 4.7 with:

sConfig.Rank = ADC_RANK_CHANNEL_NUMBER;

Best regards
