This example shows how you can use signal functions in the Visiondebugger to simulate a signal that is coming into one of the analog inputs of the LPC21xx.The Measure example is described in detail in the Getting StartedUser's Guide.The MEASURE example program is available for several targets:Simulator: uVision Simulator for LPC2129MCB2100: Keil MCB2100 evaluation board with ULINK debugger - Application is loaded to internal Flash. - Switch S2 (INT1) is used as GPIO and sampled (jumper positions: J1= off, J7= on) - potentiometer POT1 is sampled as AIN0 (jumper position: J2= on) - serial port COM1 parameters: 9600 baud, no parity, 8-bits, 1 stop bit, flow control noneMCB2130: Keil MCB2130 evaluation board with ULINK debugger - Application is loaded to internal Flash. - Switch S2 (INT1) is used as GPIO and sampled (jumper positions: J1= off, J7= on) - potentiometer POT1 is sampled as AIN1 (jumper position: J2= on) - serial port COM1 parameters: 9600 baud, no parity, 8-bits, 1 stop bit, flow control none

一、建焊盤打開建立焊盤的軟件Pad Designer路徑:包括采用的制式,現在選公制單位毫米,精度3,右側問是否需要多重鉆孔,這個功能一般是用于做非圓孔。一般圓孔不用勾選。下面設定鉆孔樣式,一般是圓孔,鉆孔內部是否鍍銅 plated(no plated即為不鍍銅,一般用于塑膠件定位孔),再是鉆孔直徑,設置精度,是否偏移等。如果是表貼元件,鉆孔直徑設為0。如果是表面安裝元件,把signle layer mode勾選。焊盤一般需要 begin layer和end layer,還有就是soldmask_top,soldmask_bottom,pastemask top,pastemask bottom這幾個層面。對表面安裝元件來說,只需要begin layer,soldermask_top以及pastemask_top就可以了。鼠標左鍵點擊begin layer,會發現最下面三個對話框被刷新,在下面填入需要的值:從左到右:規則焊盤,熱焊盤,反焊盤。1規則焊盤下面需要填入焊盤形狀,長寬,是否有偏移。1熱焊盤,要求選擇焊盤類型,尺寸等;1反焊盤,作用是設定焊盤與周邊間距,一般比規則焊盤略大6-10mil。鼠標點擊soldermask_top,下面對話框刷新出該選項。按照需要填入數據。Pastemask top同樣處理。右邊上角還有視圖角度選擇,Xsection為水平視圖,TOP為從上往下看。

交換(switching)是按照通信兩端傳輸信息的需要,用人工或設備自動完成的方法,把要傳輸的信息送到符合要求的相應路由上的技術的統稱。交換機根據工作位置的不同,可以分為廣域網交換機和局域網交換機。廣域的交換機(switch)就是一種在通信系統中完成信息交換功能的設備,它應用在數據鏈路層。交換機有多個端口,每個端口都具有橋接功能,可以連接一個局域網或一臺高性能服務器或工作站。實際上,交換機有時被稱為多端口網橋。 [1] 在計算機網絡系統中,交換概念的提出改進了共享工作模式。而HUB集線器就是一種物理層共享設備,HUB本身不能識別MAC 地址和IP地址,當同一局域網內的A主機給B主機傳輸數據時,數據包在以HUB為架構的網絡上是以廣播方式傳輸的,由每一臺終端通過驗證數據報頭的MAC地址來確定是否接收。也就是說,在這種工作方式下,同一時刻網絡上只能傳輸一組數據幀的通訊,如果發生碰撞還得重試。這種方式就是共享網絡帶寬。通俗的說,普通交換機是不帶管理功能的,一根進線,其他接口接到電腦上就可以了
