CubeIDE Ver1.13.1的hadc1初始化代码默认enable了OversamplingMode

regsofweb

日，同时用到了ADC1和ADC2，一样的设置，运行发现adc1超时。最后发现cubemx生成的初始化里面adc1的OversamplingMode是enable，adc2的OversamplingMode是disable。
把 hadc1.Init.OversamplingMode = ENABLE; 改成 DISABLE就可以了

找到了原因。之前设置中，先是enable了regular conversion，也enable了oversample。后来修改直接diable了regular conversion，这时oversample那个选项就不可见了（其实还是enable的状态）。然后generate code后，oversample还是保持了ENABLE的设定。
