看到最近大家都关心 usbhost 的实现, 论坛上能找到的代码仅是一些简单的 demo , 完整的源码级的协议层是找不到的 我就贡献一把, 将我前一段时间移植成功的 USBHost 代码奉上 注意事项 1. ohci 层移植自 u-boot-1.3.2-rc3 2. fat 层移植自 gba_nds_fat 3. 本代码只是我产品中的一部分, 使用 Keil RTL 操作系统, 任务为 void task_usb(void) __task 保证完整, 想要跑起来可能需要做些修改与测试-?#39 ??????#39 蠹??脊匦?usbhost 的实现, 论坛上能找??的

由于输出的是方波，比较难听:-) 只能说是非常难听:-)为什么呢？只因为输出的是方波,包含了大量的奇次谐波。 你可以用双龙的"虚拟仪器"分别产生正弦波、三角波和方波听一下，正弦波感 觉就比较纯正，而方波则要多难听有多难听！-As the output is a square wave, more bluntly :-) can only say that it is very nasty :-) Why? Simply because the output is square wave, including a large number of odd harmonics. You can use Shuanglong
