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。

The LPC1850/30/20/10 are ARM Cortex-M3 based microcontrollers for embeddedapplications. The ARM Cortex-M3 is a next generation core that offers systemenhancements such as low power consumption, enhanced debug features, and a highlevel of support block integration.The LPC1850/30/20/10 operate at CPU frequencies of up to 150 MHz. The ARMCortex-M3 CPU incorporates a 3-stage pipeline and uses a Harvard architecture withseparate local instruction and data buses as well as a third bus for peripherals. The ARMCortex-M3 CPU also includes an internal prefetch unit that supports speculativebranching.The LPC1850/30/20/10 include up to 200 kB of on-chip SRAM data memory, a quad SPIFlash Interface (SPIFI), a State Configuration Timer (SCT) subsystem, two High-speedUSB controllers, Ethernet, LCD, an external memory controller, and multiple digital andanalog peripherals.
