RM44L485 外设

TI各位好，我想问下，现在项目中要使用ADC的自检功能，该怎样使用。

Susan Yang：

我在TI网站内没有找到您给出的芯片型号，请您先确认一下，谢谢

Susan Yang：

在用户指南的 20.8.2 ADC Self-Test Mode中，您可以看到具体的内容

Self-test mode is enabled by setting the SELF_TEST bit (ADCALCR.24). Any conversion type (continuous or single conversion, freeze enabled or non-freeze enabled, interrupts enabled or disabled) can be performed in this mode.

In normal mode, setting the self-test mode while a conversion sequence is in process can corrupt the current channel conversion results. However, the next channel in the sequence is converted correctly during the additional self-test cycle.

请您先看一下，若是还有具体问题，您可以继续跟帖
