The 6-channel ADC is converted to DMA but only the first channel is changed?

Here is my program, but only the first route has AD change, but I give 3.3V or 0V.I use Cubelde 1.3.0 and CuBlemx6.2.0 software.

  • I don't know why not enter the ADC callback function?

  INT8U AdcChFlags;

  uint16_t AdcConvertedValue[12];

  • Why is there no code for the DMA register?
