STM32 的 DAC 模块(数字/模拟转换模块)是 12 位数字输入，电压输出型的DAC。DAC 可以配置为 8 位或 12 位模式，也可以与 DMA 控制器配合使用。DAC工作在 12 位模式时，数据可以设置成左对齐或右对齐。DAC 模块有 2 个输出通道，每个通道都有单独的转换器。在双DAC 模式下，2 个通道可以独立地进行转换，也可以同时进行转换并同步地更新 2 个通道的输出。DAC 可以通过引脚输入参考电压 VREF+以获得更精确的转换结果。
The DAC module of STM32 (digital / analog conversion module) is a 12 bit digital input, voltage output type DAC. DAC can be configured as 8 bit or 12 bit mode, and can also be used in conjunction with DMA controller. When DAC works in 12 bit mode, data can be left aligned or right aligned. The DAC module has 2 output channels, each with separate converters. In the dual DAC mode, the 2 channels can be converted independently, and can also be converted at the same time and synchronously update the output of the 2 channels. DAC can input the reference voltage VREF+ by pin to get more accurate conversion results. (2018-05-18, MDK, 336KB, 下载0次)
