Does STM32 support dual-ADC multi-channel sampling? For example, ADC1 enables IN1 and IN2, and ADC2 enables IN3 and IN4. Is the storage method in the adc_buffer as follows? adc_buffer[0]: High 16 bits = ADC1 IN1, Low 16 bits = ADC2 IN3 adc_buffer[1]: High 16 bits = ADC1 IN2, Low 16 bits = ADC2 IN4 And how should I configure this in CubeMX?

Does STM32 support dual-ADC multi-channel sampling? For example, ADC1 enables IN1 and IN2, and ADC2 enables IN3 and IN4. Is the storage method in the adc_buffer as follows?

adc_buffer[0]: High 16 bits = ADC1 IN1, Low 16 bits = ADC2 IN3
adc_buffer[1]: High 16 bits = ADC1 IN2, Low 16 bits = ADC2 IN4

And how should I configure this in CubeMX?

In general, yes, although samples will be interleaved. Look up dual mode interleaved in the relevant Reference Manual of your chip.
