Example description
===================
This example describes how to convert ADC regular group channels continuously using
TIM1 external trigger and injected group channels using the auto-injected feature.
The ADC is configured to convert on each TIM1 rising edge ADC channel14.
Each time an end of regular conversion occurs the DMA transfers, the converted data 
from ADC1 DR register to the ADC_RegularConvertedValueTab table. 
Enabling the auto-injected feature, permit to convert automatically the injected 
channel ADC channel11 after the end of the regular channel14. An ADC interrupt is 
generated then by JEOC flag at the end of the injected channel conversion and in 
the interrupt routine the result is stored in the ADC_InjectedConvertedValueTab table.
The procedure is repeated 32 times then the TIM1 peripheral is disabled and thus, 
no conversion will be done neither regular or injected.
TIM1 start conversion triggers can be visualized on oscilloscope on PA.08 and at the
same time the toggle of pin PC06 which indicates the automatic auto-injection 
conversion.
The ADC1 clock is set to 14 MHz.

Hardware environment
====================
 - Connect a known voltage, between 0-3.3V, to ADC Channel14 mapped on pin PC.04
   (potentiometer RV1 on STM3210B-EVAL board) and ADC Channel11 mapped on pin PC.01
   
      
How to use it
=============
In order to make the program work, you must do the following :
- Create a project and setup all your toolchain's start-up files
- Compile the directory content files and required Library files :
  + stm32f10x_lib.c
  + stm32f10x_adc.c
  + stm32f10x_dma.c
  + stm32f10x_tim1.c
  + stm32f10x_gpio.c
  + stm32f10x_rcc.c
  + stm32f10x_nvic.c
  + stm32f10x_flash.c
  
- Link all compiled files and load your image into either RAM or FLASH
- Run the example
