This application note describes the three methods that can be used to program the Flash code memory of the 89C51Rx+/Rx2/66x families of microcontrollers. It discusses in detail the operation of the In-System Programming (ISP) capability which allows these microcontrollers to be programmed while mounted in the end product. These microcontrollers also have an In-Application Programming (IAP) capability which allows them to be programmed under firmware control of the embedded application. This capability is also described

Airline Reservations System A small airline has just purchased a computer for its new automated reservation system. You have been asked to develop the new system called ARSystem. You are to write an application to assign seats on each flight of the airline s only plane (capacity: 24 seats.) Your application should display the following alternatives: Please type 1 for FirstClass and Please type 2 for Economy. If the user types 1, your application should assign a seat in the first-class section (seats 1-8). If the user types 2, your application should assign a seat in the economy section (seats 9-24). Your application should then display a boarding pass indicating the person s seat number and whether it is in the first-class or economy

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

C280x C/C++ Header Files and Peripheral Examples The DSP28xx C/C++ peripheral header files and example projects files facilitate writing C/C++ Code for the TI鈥檚 28xx MCUs. The code can be used as a learning tool or as the basis for a development platform depending on the current needs of the user. We suggest that you immediately download these header files in order for an easier transition to understanding the 28xx peripherals.
