&par Example Description

This example describes how to trigger ADC regular and injected groups channels 
conversion using two external line events. Discontinuous mode is enabled for regular
group channel conversion and configured to convert one regular channel on each 
external trigger.

ADC1 is configured to start regular group channel conversion on EXTI15 event.
On detection of the first rising edge on PE15 pin, the conversion of the first regular 
channel (ADC1 channel1) is done and its converted value is transferred by DMA to 
ADC_RegularConvertedValueTab table. 

Provide a rising edge for PE15, the converted voltage will display on serial assistant 
through USART1.

  - USART1 and USART2 configured as follow:
  - BaudRate = 115200
  - Word Length = USART_WordLength_8b
  - Stop Bit = USART_StopBits_1
  - Parity = USART_Parity_No
  - Hardware flow control disabled (RTS and CTS signals)
  - Receive and transmit enabled
