  • 遥控在客厅—自制USB电脑遥控器

    接收器像个U盘一样插在笔记本侧面,遥控器没有对准红外接收头啊。这里其实没太大关系的,没对准的话,白色墙面也能帮你反射,还不满意的话可以用USB 延长线调整。实际测试,支持家里几乎所有遥控型号,测试距离4.5 米,在两台电脑上测试成功,支持常规功能和高级功能,更多功能期待和大家一起完善。

  • 无线电干扰 Radio Susceptibility

      Abstract: Engineers often wish that radio susceptibility (RS) or radio immunity could be cured with an antibiotic, a vaccine, or someform of cure-all. Unfortunately, solving the RS problem is not that easy. Indeed, the laws of physics apply. In this article we discusssources of RS. We also offer tips and hints to protect systems, power supplies, printed circuit boards (PCBs), and electroniccomponents from radio frequency interference.

  • 基于USB总线的ADSP-TS101S链路口加载

        在DSP系统上运行的程序,系统上电复位后需要加载程序到DSP的程序存储器内。这是使用外部加载模式时的系统开发不可缺少的环节。针对实际需求,提出了一种使用USB对ADSP_TS101S进行链路口加载的方案,并介绍了设计思想和实现过程。实际应用的试验证明,提出的加载方案有效且简单易行。
