使用簡單: 用 控件->Active=true 打開串口 控件->Read()讀, 控件->Write()寫. 可以處理控件的事件, 但不是必須的.

procedure senddata var i:integer commflg : Boolean begin commflg:=true for i:=1 to 8 do begin if not fcomm comml writecommdata(sendbutter,i) then begin Commflg=false break end end end (4) 接收數據 在編寫基于串口的計算機工業測控時，通常需要由下位機向PC機發送數據以使PC機了解系統的測試數據或下位機的運行狀態，并進而控制下位機的行為。利用Spcomm串口控件接收下位機發送的數據信息的示例代碼如下： //事件驅動方式接收數據程序 procedure TForm1.CommlReceiveData(Sender:Tobject Buffer:Pointer bufferLength:Word) var receivedata:array of byte begin sleep(100) //等待100ms，保證接收到所有數據 move(buffef ,receivedata,bufferlength) //將接收緩存區中的數據轉移到數組中 …… end (5) 關閉串口 在系統開發中，應注意在不使用串口時應及時關閉串口，釋放系統資源，否則可能會影響系統的其它應用。關閉串口的代碼如下： procedure TForm1.FormClose ( Sender TObj ect:var Action:TCIoseAction ) begin comml.StopComm end

a true random number generator (TRNG) in hardware which is targeted for FPGA-based crypto embedded systems. All crypto protocols require the generation and use of secret values that must be unknown to attackers.Random number generators (RNG) are required to generate public/private key pairs for asymmetric algorithm such as RSA and symmetric algorithm such as AES.

The LTC®1966 is a true RMS-to-DC converter that uses aDS computational technique to make it dramatically simplerto use, significantly more accurate, lower in powerconsumption and more flexible than conventional logantilogRMS-to-DC converters. The LTC1966 RMS-to-DCconverter has an input signal range from 5mVRMS to1.5VRMS (a 50dB dynamic range with a single 5V supplyrail) and a 3dB bandwidth of 800kHz with signal crestfactors up to four.

Differential Nonlinearity: Ideally, any two adjacent digitalcodes correspond to output analog voltages that are exactlyone LSB apart. Differential non-linearity is a measure of theworst case deviation from the ideal 1 LSB step. For example,a DAC with a 1.5 LSB output change for a 1 LSB digital codechange exhibits 1⁄2 LSB differential non-linearity. Differentialnon-linearity may be expressed in fractional bits or as a percentageof full scale. A differential non-linearity greater than1 LSB will lead to a non-monotonic transfer function in aDAC.Gain Error (Full Scale Error): The difference between theoutput voltage (or current) with full scale input code and theideal voltage (or current) that should exist with a full scale inputcode.Gain Temperature Coefficient (Full Scale TemperatureCoefficient): Change in gain error divided by change in temperature.Usually expressed in parts per million per degreeCelsius (ppm/°C).Integral Nonlinearity (Linearity Error): Worst case deviationfrom the line between the endpoints (zero and full scale).Can be expressed as a percentage of full scale or in fractionof an LSB.LSB (Lease-Significant Bit): In a binary coded system thisis the bit that carries the smallest value or weight. Its value isthe full scale voltage (or current) divided by 2n, where n is theresolution of the converter.Monotonicity: A monotonic function has a slope whose signdoes not change. A monotonic DAC has an output thatchanges in the same direction (or remains constant) for eachincrease in the input code. the converse is true for decreasing codes.
