Hi everyone,
I want to make a small demo for Open Firmware to show that it can play a music. the very basic is : play, pause, play with play, I use tone . but, I can't find WORD for pause, where is it?
For pause, do you mean a time delay? If so, you can use
ms ( #msecs -- )
For example
d# 1000 ms
will delay for 1 second.
further more, I read some articles about midi file. It's a little complicated for me. So I want to finished the first tone-music first :)
PS: Are there some detail articles about Open Firmware handle with music? wav, midi, mp3 or event avi?
OFW can play .wav files - see cpu/x86/adpcm.fth .
OFW does not have any built-in support for midi or mp3. Midi playback requires sound synthesis code or a hardware sound synthesizer. mp3 playback requires a patent license from Fraunhofer so I cannot include that capability in free software.
I'm not sure what you mean by "event avi".
