看看这个IC, 有希望在上面找到数字输出吗
买了个单锭的车载播放器, 无损有损几乎所有音频格式通吃, 意在改个简单的数字音源.拆开却发现是单片方案, 没有独立DAC片, 处理器应该是国产的, 网上没有资料, 也几乎
无人提及, 发上来大家看看, 有谁认识它? 帮忙指点下它有没有数字输出,是哪个或哪
些脚. 脚真多。。。 要不，学习一下以前CD改VCD时的做法，一个个脚试… 这芯片的标示。。。好气人的:lol 实在没有资料的话，按照3楼的方法试，;P 只能用示波器看了? 指甲大的片子128个脚啊, 放大镜下面都不一定好数, 弄疲了一不小心就短路的, 难度挺大的. 没有数字音频输出，连GPIO的可选编程列表里面也没有该类选项，废物。结帖！
