TIM7 TRGO selected as external conversion trigger for DAC channel
时间: 2024-06-05 16:12:15 浏览: 6
This message is related to configuring a DAC (Digital-to-Analog Converter) channel in a microcontroller or similar device.
In this case, the TIM7 TRGO (Timer 7 Trigger Output) is being used as an external conversion trigger for the DAC channel. This means that the DAC channel will convert digital values to analog signals based on the timing signals generated by Timer 7.
Using an external trigger like this can help synchronize the conversion of multiple DAC channels or tie the conversion to an external event.

In software mode, the channels for conversion are selected by control of the channel register. On power-up or after a reset, the default channels selected for conversion are Channel V0A and Channel V0B
根据你提供的上下文信息,我的理解是在软件模式下,通过控制通道寄存器来选择要进行转换的通道。在上电或重置后,选择进行转换的默认通道是通道V0A和通道V0B。这意味着如果没有显式地更改通道寄存器中的通道选择,那么在软件模式下进行转换时,将默认使用通道V0A和通道V0B进行转换。请注意,这里提到的默认通道仅适用于软件模式下的转换。
variant conversion error for v
"variant conversion error for v" 意思是变量 v 的类型转换错误。这通常是由于试图将一个变量转换为不兼容的类型导致的。例如,尝试将一个整型变量转换为字符串变量。解决方法是检查代码,确保正确转换变量的类型。
