i2c中，“master mode 、slave mode”是什么意思？
推荐回答（1个）
master mode 主机模式 （下面例子中老大的模式）
slave mode 从机模式 （下面例子中小混混的模式）
master or slave transmit mode 主机或者从机 发送模式
master or slave receive mode 主机或者从机 接受模式
i2c是一个传输的协议，可以通过协议来传递数据，需要有SCL时钟线和SDA数据线
主机就像老大，控制时钟线，从机就像小混混，小混混可以有1个或者多个 每个有固定的编号
也就是地址，老大如果要叫小混混打一个人，先发送小混混的编号（地址），小混混确认后，老
大再发打人的资料（数据），然后小混混得到数据 ，去执行，这就是主机模式！
英语（English）是印欧语系-日耳曼语族下的语言，由26个字母组合而成，英文字母渊源于拉丁字母，拉丁字母渊源于希腊字母，而希腊字母则是由腓尼基字母演变而来的。英语是国际指定的官方语言（作为母语），也是世界上最广泛的第一语言，英语包含约49万词，外加技术名词约30万个，是词汇最多的语言，也是欧盟以及许多国际组织以及英联邦国家的官方语言，拥有世界第三位的母语使用者人数，仅次于汉语和西班牙语母语使用者人数。
英语由古代从丹麦等斯堪的纳维亚半岛以及德国、荷兰及周边移民至不列颠群岛的盎格鲁、撒克逊以及朱特部落的白人所说的语言演变而来，并通过英国的殖民活动传播到了世界各地。由于在历史上曾和多种民族语言接触，它的词汇从一元变为多元，语法从“多屈折”变为“少屈折”，语音也发生了规律性的变化。在19至20世纪，英国以及美国在文化、经济、军事、政治和科学在世界上的领先地位使得英语成为一种国际语言。如今，许多国际场合都使用英语做为沟通媒介。
英语也是与电脑联系最密切的语言，大多数编程语言都与英语有联系，而且随着网络的使用，英文的使用更普及。英语是联合国的工作语言之一。 苏格兰语、低地撒克逊语、丹麦语、德语、荷兰语、南非荷兰语和英语也很接近。拥有法国血统的诺曼人于11世纪征服英格兰王国，带来数万法语词汇和拉丁语词汇，很大程度地丰富了英语词汇外，相对也驱使不少原生的语汇作废。
