The main function initializes the ADC, LCD, VDAC, Analog Buffer, and UART.
It also initializes DMA by allocating/configuring a DMA channel and
Transaction Descriptor and also copies the voltage table address to the DAC
address. In the main loop, it starts and waits for an ADC conversion, then
it displays the ADC raw count to the LCD, transmits the raw count serially,
and sets the DMA clock divider proportional to the raw count.
