基于单片机的MIDI文件中delta-time的实现

Implement of delta-time in MIDI File Based on Signal-Chip Microcomputer

在单片机与某些MIDI模块进行通信时,由单片机将MIDI文件发送给MIDI模块时,MIDI模块仅能执行MIDI命令,不能识别和执行MIDI文件中的delta-time,而delta-time又是MIDI文件中非常重要的部分,在这种情况下单片机就要根据delta-time的特征,完成识别并执行delta-time的任务。

When microcomputer communicates MIDI data with some MIDI module, the MIDI module can only executes MIDI messages, it can＇t identify delta-time from MIDI file. But deltatime is a very important part of MIDI file. In this case, it＇s important to know how the signal-chip microcomputer identify delta-time and execute it.
