+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 EXTI11 event.
+On detection of the first rising edge on PE.11 pin, the conversion of the first regular
+channel (ADC channel4) is done and its converted value is transfered by DMA to
+ADC_RegularConvertedValueTab table. On the following edge detection, the second
+regular channel (ADC channel14) is automatically converted and its converted value
+is stored by DMA in the same table. The number of transmitted data by DMA, in this
+example is limited to 64 data.
+
+The procedure is repeated for both regular channels on each EXTI11 event.
+ADC1 is configured to start injected group channel conversion on EXTI15 event.
+On detection of the first rising edge on PE.15 pin all selected injected channels, which
+are two in this example (ADC channel11 and channel12), are converted and an interrupt
+is generated on JEOC flag rising at the end of all injected channels conversion.
+Both injected channels converted results are stored in ADC_InjectedConvertedValueTab
+table inside the interrupt routine.
+The procedure is repeated for injected channels on each EXTI15 event.
+The ADC1 clock is set to 14 MHz.

+
+Hardware environment
+====================
+This example runs on STMicroelectronics STM3210B-EVAL and STM3210E-EVAL evaluation
+boards and can be easily tailored to any other hardware.
+
+ - Connect a known voltage, between 0-3.3V, to ADC Channel14 mapped on pin PC.04
+ (potentiometer RV1 on STM3210B-EVAL and STM3210E-EVAL boards), ADC Channel4 mapped
+ on pin PA.04, ADC Channel11 mapped on pin PC.01 and ADC Channel12 mapped on pin PC.02.
+ - Connect a push-button to pin PE.11 (EXTI Line11) and another push-button to
+ pin PE.15 (EXTI Line15).
+
+
+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_exti.c
+ + stm32f10x_gpio.c
+ + stm32f10x_rcc.c
+ + stm32f10x_nvic.c
+ + stm32f10x_flash.c
+
+- Link all compiled files and load your image into target memory
+- Run the example
