然而，我想要能够设置一个超时值，以便它不会卡住，如果说在总线上没有设备。
但是在超时之后，如果我尝试启动另一个异步读写适配器挂起，因为有(例如2)未完成的挂起事务。我如何取消这些挂起的事务，或者更好的是，如何使用ad_i2c_async_read或ad_i2c_async_write超时。< / p > < / div > < / div > < / div > < div class =”字段field-name-field-forum-keywords field-type-taxonomy-term-reference field-label-above”> < div class = "字段标签" >关键词:,< / div > < div class = "字段条目" > < div class =”field-item甚至“> < a href = " / resource-keywords / i2c”“=“skos:概念”属性=“rdfs: label skos: prefLabel”数据类型= " " > i2c < / > < / div > < div类= " field-item奇怪" > < a href = " / resource-keywords / adi2c”“=“skos:概念”属性=“rdfs: label skos: prefLabel”数据类型= " " > ad_i2c < / > < / div > < div class =”field-item甚至“> < a href = " / resource-keywords /大师”“=“skos:概念”属性=“rdfs: label skos: prefLabel”数据类型= " " >主< / > < / div > < div class = " field-item古怪”> 超时< / > < / div > < div class =”field-item甚至“> < a href = " / resource-keywords / freertos”“=“skos:概念”属性=“rdfs: label skos: prefLabel”数据类型= " " > freertos < / > < / div > < div class = " field-item古怪”> < a href = " / resource-keywords /异步”typeof = " skos:概念”属性= " rdfs: label skos: prefLabel”异步数据类型= " " > < / > < / div > < div class =”field-item甚至“> < a href = " / resource-keywords /适配器”“=“skos:概念”属性=“rdfs: label skos: prefLabel”数据类型= " " >适配器< / > < / div > < / div > < / div > < div class = "字段field-name-field-device field-type-taxonomy-term-reference field-label-above">
