可以提供一个CH32V307RCT6 的多个触摸按键的ADC 和 别的 ADC采样一起使用采集的例程吗？我这里不知道为啥总会有点问题，
不用这个
// while(!ADC_GetFlagStatus(ADC1, ADC_FLAG_EOC))
// ;
用和这个的话
if(ADC_GetFlagStatus(ADC1, ADC_FLAG_EOC) == 0)
{
}
else
{
TK2_Data = (uint16_t)TKey1->RDATAR;
}
总有个ADC的值是错的

别的地方还用着一个通道10在采集着别的东西
不支持ADC模块与触摸按键同时采样，触摸按键结束后，可以关闭TKENABLE 进行ADC采样。
