-=== DAC ===
-* The output impedance is a concern. Without the Output Buffer enabled, >100kohm impedance for the load is recommended. Even WITH Output Buffer enabled, a 1kohm load is not really possible, both high and low end of range is not reached, which is a bit strange. 10kohm hasn't been tested yet.
-* For fastest write to DAC output, this is used;
- <nowiki>
-DAC->RD12BDHR = dac_value1 + (dac_value2 << 16);
-</nowiki>
-* Simple initialization is;
- <nowiki>
-    RCC_APB1PeriphClockCmd(RCC_APB1Periph_DAC, ENABLE );
-    DAC_InitTypeDef DAC_InitType={0};
-    DAC_InitType.DAC_Trigger=DAC_Trigger_None;
-    DAC_InitType.DAC_WaveGeneration=DAC_WaveGeneration_None;
-    DAC_InitType.DAC_OutputBuffer=DAC_OutputBuffer_Enable;
-    DAC_Init(DAC_Channel_1,&DAC_InitType);
-    DAC_Init(DAC_Channel_2,&DAC_InitType);
-    DAC_Cmd(DAC_Channel_1, ENABLE);
-    DAC_Cmd(DAC_Channel_2, ENABLE);
-</nowiki>
