21 @par Example Description
22
23 This example describes how to use one DAC channel to generate a signal with noise
24 waves on DAC Channel1 output.
25
26 DAC channel1 conversion are configured to be triggered by software with noise wave
27 generation.12bit left data alignment is selected since we choose to access DAC_DHR12L1
28 register. Bits 0 to 8 are masked for the Linear feedback shift register.
29 DAC channel1 is then enabled. DAC Channel1 DHR12L1 register is configured to have
30 an output voltage of VREF/2.
31
32 Software triggers are generated continuously in an infinite loop, and on each
33 trigger the DAC channel1 start the conversion and calculate the noise value to
34 apply on the DAC channel1 output.
35
36 The output signal with noise waves can be visualized by connecting PA.04 pin to
37 an oscilloscope.

72 @par How to use it ?
73
74 In order to make the program work, you must do the following :
75 - Copy all source files from this example folder to the template folder under
76 Project\STM32F10x_StdPeriph_Template
77 - Open your preferred toolchain
78 - Rebuild all files and load your image into target memory
79 - Run the example
