OBD（On-Board Diagnostics），即随车诊断系统，可以通过汽车上安装的随车诊断装置，实时监测汽车的运行状况。美国汽车工程师协会（SAE）制定的汽车OBD 1随车诊断系统，统一了故障诊断接口和故障代码的设置及含义。随车诊断系统的不足之处是只能提供某一特征故障的故障代码与某些故障数据，不能对维修人员给以更具体的指导 ...

1、安装完成后，点击Continue Free，进入下一步。2、如上图依次点击1-4，选择下图所示从TI官网下载的封装文件，导出所需软件的封装配置文件。注：这里导出的还只是配置文件，需再做一些操作才能生成Allegro的原件库文件。3、导出文件后，配置文件会自动尝试生成原件封装，但是肯定会失败。这时需要把自动打开的txt文件中如 ...
