    <description>&lt;P&gt;Hi,&lt;BR /&gt;感谢回复，正如我上面说的，你可以通过以下连接下载对应i.MX RT的SDK 软件包，里面就有ADC例程。&lt;BR /&gt;Have a great day,&lt;BR /&gt;TIC&lt;/P&gt;

      <description>&lt;P&gt;我的问题如下：&lt;/P&gt;&lt;P&gt;用MIMXRT1011 51号管脚&amp;nbsp;&amp;nbsp; GPIO_AD_07通道采集电池电压，电池电压7.3V ，经75K、39K电阻分压后给MCU采集，理论应该为2.50V，实测2.61V，采样数值不准确，请问MCU的IO口配置是否有影响？该怎么配置，thank you !&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;得到的回复如下：&lt;/P&gt;&lt;P&gt;你好，&lt;/P&gt;&lt;P&gt;我们发现ADC采样结果会受到异步ADC时钟供电源的干扰，造成采样结果产生大范围偏差。&lt;/P&gt;&lt;P&gt;我们建议客户使用IPG时钟，并且将ADCx_GC[ADACKEN] 位设置成 0；&lt;/P&gt;&lt;P&gt;如果需要使用ADC异步时钟，则需要IPG时钟设置为无效。&lt;/P&gt;&lt;P&gt;希望对你的问题有所帮助&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;时间过去很久了&amp;nbsp; AD这一问题还没解决&amp;nbsp; 软件上不知道怎么配置 看能否发些AD例程过来&amp;nbsp; 帮我解决这个问题 谢谢&amp;nbsp; 我们是做打印机的&lt;/P&gt;</description>

      <description>&lt;P&gt;Hi,&lt;BR /&gt;非常感谢使用NXP产品，很高兴为你提供技术支持！&lt;BR /&gt;关于软件实现，就是在ADC初始化过程中，在ADCx_CFG寄存器中设置ADICLK选择IPG clock作为时钟源，接着ADCx_GC[ADACKEN] 位设置成 0，其他软件部分保持不变。&lt;BR /&gt;至于ADC例程，我建议参考&lt;A href="https://mcuxpresso.nxp.com/en/welcome" target="_self"&gt;SDK软件库&lt;/A&gt;中的ADC例程，可以在其例程基础上很容易修改ADC配置选项。&lt;BR /&gt;同时，我建议你从多方面查找问题，比如VDDADC是否稳定，采样脚附件是否有高频信号等。&lt;BR /&gt;希望这些建议对你能有所帮助。&lt;BR /&gt;Have a great day,&lt;BR /&gt;TIC&lt;/P&gt;

      <description>&lt;P&gt;能否提供一下修改好的ADC例程&amp;nbsp; 我这边软件还不会 谢谢！&lt;/P&gt;</description>
