DAC channel1 conversion is configured to be triggered by TIM6 TRGO triggers and without noise/triangle wave generation. 8bit right data alignement is selected since we choose to acces DAC_DHR8R1 register. DMA2 channel3 is configured to transfer continuously, byte by byte, a 6-byte buffer to the DAC1 register DAC_DHR8R1. The transfered 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.
