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 NXP LPC314x combine a 270 MHz ARM926EJ-S CPU core, High-speed USB 2.0OTG, 192 KB SRAM, NAND flash controller, flexible external bus interface, three channel10-bit A/D, and a myriad of serial and parallel interfaces in a single chip targeted atconsumer, industrial, medical, and communication markets. To optimize system powerconsumption, the LPC314x have multiple power domains and a very flexible ClockGeneration Unit (CGU) that provides dynamic clock gating and scaling.

The LPC4350/30/20/10 are ARM Cortex-M4 based microcontrollers for embeddedapplications. The ARM Cortex-M4 is a next generation core that offers systemenhancements such as low power consumption, enhanced debug features, and a highlevel of support block integration.The LPC4350/30/20/10 operate at CPU frequencies of up to 150 MHz. The ARMCortex-M4 CPU incorporates a 3-stage pipeline, uses a Harvard architecture withseparate local instruction and data buses as well as a third bus for peripherals, andincludes an internal prefetch unit that supports speculative branching. The ARMCortex-M4 supports single-cycle digital signal processing and SIMD instructions. Ahardware floating-point processor is integrated in the core.The LPC4350/30/20/10 include an ARM Cortex-M0 coprocessor, up to 264 kB of datamemory, advanced configurable peripherals such as the State Configurable Timer (SCT)and the Serial General Purpose I/O (SGPIO) interface, two High-speed USB controllers,Ethernet, LCD, an external memory controller, and multiple digital and analog peripherals
