&par Example Description

This example describes how to use the ADC to convert Channel0,Channel1 and Channel2  
simultaneously in dual mode using DMA in mode 1.

A DMA request is generated each time 2 data items are available
1st request: ADC->CDATA[31:0] = (ADC2_CH1_REGDATA[15:0] << 16) | ADC1_CH0_REGDATA[15:0]
2nd request: ADC->CDATA[31:0] = (ADC2_CH2_REGDATA[15:0] << 16) | ADC1_CH1_REGDATA[15:0]

The ADC1 are configured to convert ADC Channel 0 and Channel 1.
The ADC2 are configured to convert ADC Channel 1 and Channel 2.

The converted voltage is displayed on serial assistant through USART1.

&par Hardware Description

using ADC_Channel0(PA0)
using ADC_Channel1(PA1)
using ADC_Channel2(PA2)

The USART1 is configured as follows:
    - TX:PA9, RX:PA10
    - BaudRate = 115200 baud
    - Word Length = 8 Bits
    - One Stop Bit
    - No parity
    - Hardware flow control disabled (RTS and CTS signals)
    - Receive and transmit enabled
