+@par Example Description 
+
+This example describes how to use one DAC channel mode with DMA to generate an
+escalator signal on DAC channel1 output.
+
+DAC channel1 conversion is configured to be triggered by TIM6 TRGO triggers and
+without noise/triangle wave generation. 8bit right data alignment is selected
+since we choose to access DAC_DHR8R1 register.
+DMA2 channel3 is configured to transfer continuously, byte by byte, a 6-byte
+buffer to the DAC1 register DAC_DHR8R1.
+
+The transferred 6bytes buffer is made to have an escalator signal on DAC channel1
+output. DAC channel1 is then enabled. Once TIM6 is enabled, each TIM6 TRGO update
+event generate a DMA request which transfer data  to the DAC1 register and DAC
+conversion is started. The escalator signal can be visualized by connecting PA.04
+pin to an oscilloscope.

+@par How to use it ? 
+
+In order to make the program work, you must do the following :
+ - Copy all source files from this example folder to the template folder under
+   Project\STM32F10x_StdPeriph_Template
+ - Open your preferred toolchain 
+ - Rebuild all files and load your image into target memory
+ - Run the example 
+
+@note
+ - Low-density Value line devices are STM32F100xx microcontrollers where the 
+   Flash memory density ranges between 16 and 32 Kbytes.
+ - Low-density devices are STM32F101xx, STM32F102xx and STM32F103xx 
+   microcontrollers where the Flash memory density ranges between 16 and 32 Kbytes.
+ - Medium-density Value line devices are STM32F100xx microcontrollers where
+   the Flash memory density ranges between 64 and 128 Kbytes.  
+ - Medium-density devices are STM32F101xx, STM32F102xx and STM32F103xx 
+   microcontrollers where the Flash memory density ranges between 64 and 128 Kbytes.
+ - High-density Value line devices are STM32F100xx microcontrollers where
+   the Flash memory density ranges between 256 and 512 Kbytes.
+ - High-density devices are STM32F101xx and STM32F103xx microcontrollers where
+   the Flash memory density ranges between 256 and 512 Kbytes.
+ - XL-density devices are STM32F101xx and STM32F103xx microcontrollers where
+   the Flash memory density ranges between 512 and 1024 Kbytes.
