接收器像個U盤一樣插在筆記本側面，遙控器沒有對準紅外接收頭啊。這里其實沒太大關系的，沒對準的話，白色墻面也能幫你反射，還不滿意的話可以用USB 延長線調整。實際測試，支持家里幾乎所有遙控型號，測試距離4.5 米，在兩臺電腦上測試成功，支持常規(guī)功能和高級功能，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 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.

在DSP系統(tǒng)上運行的程序，系統(tǒng)上電復位后需要加載程序到DSP的程序存儲器內。這是使用外部加載模式時的系統(tǒng)開發(fā)不可缺少的環(huán)節(jié)。針對實際需求，提出了一種使用USB對ADSP_TS101S進行鏈路口加載的方案，并介紹了設計思想和實現(xiàn)過程。實際應用的試驗證明，提出的加載方案有效且簡單易行。
