As mentioned, most computers include a serial port. The only hardware setup required is connecting the serial cable to the serial port on the PC and the serial port on the instrument. The serial instrument may include some hardware drivers or software utilities for communication, and should include documentation on the Baud rate, packet size, stop bits, and parity bits that the instrument will use. Additionally, check the National Instruments Instrument Driver Network to see if LabVIEW drivers already exist for yout instrument, as

自己编写的串口-CAN口的转换程序，已经测试过没有问题！ 一.传输数据协议： 1.初始化 初始化波特率（CAN）：$Baud（$：起始符；Baud：波特率标识符； 相应编码：0x24 0x42 0x41 0x55 0x44） 传输ID号设置：$IDERSTD（相应编码：0x24 0x49 0x44 0x45 0x52 0x53 0x54 0x44） $IDEREXT（相应编码：0x24 0x49 0x44 0x45 0x52 0x45 0x58 0x54） （$：起始符；IDER：ID标识符；STD：标准帧；EXT：扩展帧） 2.数据发送 发送数据 ：$DATA（$：起始符；DATA：数据标识符 相应编码：0x24 0x44 0x41 0x54 0x41）

RS232.C was written to provide all of the basic functionality needed to employ serial I/O in any application written with Borland C language compilers. Some features are: 1. Ease of use. No assembly language or library files are used and a simple "#include" statement is all that is required to access all of the functions provided. 2. Both input and output are buffered and interrupt driven for efficiency. 3. Serial ports 1 - 4 are supported on PC, AT and PS/2 compatibles.Chained interrupts used on port 3 and 4 are allowed for so as not to interfere with devices such as a mouse or printer. Transmission speeds of 110 to 115200 Baud are available. 4. Detection and utilization of hardware buffered UARTs (NS16550AF etc.) found in some machines is automatic. 5. Interrupt driven hardware and XON/XOFF flow control is provided for. 6. All source code is included. RS232.C can be used with all memory models.

Echo a received character, RX ISR used. Normal mode is LPM0. // USART1 RX interrupt triggers TX Echo. // Baud rate divider with 1048576hz = 1048576/38400 = ~27.31 (01Bh|03h) // ACLK = LFXT1 = 32768Hz, MCLK = SMCLK = default DCO = 32 x ACLK = 1048576Hz // //* An external watch crystal between XIN & XOUT is required for ACLK

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
