richardv 0:b079fa4ed182 32 @par Example Description
richardv 0:b079fa4ed182 33
richardv 0:b079fa4ed182 34 This example provides a description of how to use a DMA channel to transfer
richardv 0:b079fa4ed182 35 data buffer from RAM memory to DAC.
richardv 0:b079fa4ed182 36
richardv 0:b079fa4ed182 37 DMA1 channel3 is configured to transfer continuously, word by word, a 32-word buffer
richardv 0:b079fa4ed182 38 to the dual DAC register DAC_DHR12RD. Both DAC channels conversions are configured
richardv 0:b079fa4ed182 39 to be triggered by TIM2 TRGO triggers and without noise/triangle wave generation.
richardv 0:b079fa4ed182 40 12bit right data alignment is selected since we choose to access DAC_DHR12RD register.
