可以提供一個CH32V307RCT6 的多個觸摸按鍵的ADC 和 別的 ADC采樣一起使用采集的例程嗎？我這里不知道為啥總會有點問題，
不用這個
//? ? while(!ADC_GetFlagStatus(ADC1, ADC_FLAG_EOC))
//? ? ;
用和這個的話??
?if(ADC_GetFlagStatus(ADC1, ADC_FLAG_EOC) == 0)
? ? {
? ? }
? ? else
? ? {
? ? ? ? TK2_Data = (uint16_t)TKey1->RDATAR;
? ? }
總有個ADC的值是錯的

別的地方還用著一個通道10在采集著別的東西
不支持ADC模塊與觸摸按鍵同時采樣，觸摸按鍵結(jié)束后，可以關(guān)閉TKENABLE 進行ADC采樣。
