| volatile uint32_t* ADC_Input_Buffer |
Buffer to store samples transfered from the ADC by a DMA.
The DMA is configured to continually transfer samples from the ADC(s) into the ADC_Input_Buffer. When the buffer is half-full or full, an interrupt is generated to allow the valid samples to be translated into float values and handed to the user.
In Mono input mode, samples are 12-bits, left-aligned in the least significant 16 bits of each word of the buffer. In Stereo input mode, the least significant 16 bits holds channel 1, and the most significant 16 bits holds the channel 2 data.

| volatile uint32_t* DAC_Output_Buffer |
Buffer to hold samples to be transfered to the DAC(s) by a DMA.
A DMA is configured to continually transfer samples from DAC_Output_Buffer to the DAC(s).
In Mono input mode, samples are 12-bits, left-aligned in the least significant 16 bits of each word of the buffer. In Stereo input mode, the least significant 16 bits holds channel 1, and the most significant 16 bits holds the channel 2 data.
