虚心请教一个GPIB接口编程的基础问题,大家不要骂我笨。
仪器写到GPIB有两个数据,用labwindows/CVI从GPIB读取数据的时候, 如果想分别存成
两个变量,应该怎么写啊? ibrd()只能指定读取的byte,该怎么写啊?
谢谢, 谢谢!!!

THis is a command in labwindows.
int result = OpenComConfig (int COMPort, char deviceName[], long baudRate,
int parity, int dataBits, int stopBits,
int inputQueueSize, int outputQueueSize);
Purpose
Opens a com port, and sets port parameters as specified. If inputQueueSize
or outputQueueSize is between 1 and 29, it is forced to 30.
Parameters
Input COMPort integer Range 1 through 32.
deviceName string Name of the COM port.
baudRate

To be more precise, it's the 16550 compatible chip which support
115200bps, not 8250.
what is labwindows?
Never heard it......
Nowadays PC always have 16550 compatible communication chips.
I can't find it now, but I remember that 128000 and 256000 is not for
serial ports. but 115200 is, maybe some driver doesn't support it.

Labwindows is a kind of foolproof software designed for
device driver or psedo real time programming. It runs
in 98/NT, so I guess the baud rate of serial port from
this command. VC should have such command too.

功能差不多,Labview用的是图形化编程语言,Labwindows就是C语言

GPIB is simple per se, you can create scripts via LabVIEW, LabWindows, VB, C
#, HP VEE, even TCL or Ruby. However, when you try to integrate a bunch of
HW(FPGA, DAQmax, GPIB, RS232, Field Point, CAN bus, etc.) to write a complex
test plan, it's always convenient to use LabVIEW/TestStand

没编过GPIB的东东,只编过PCI和PXI的 :(

If you know the format of the output data, you can certainly
write a tiny code to separate it after reading from your instrument.

来自主题: Engineering版 - cost of activation for labwindows cvi
Hi,
I am trying to activate a CVI for data acquisition on a computer. My company
has a license, but I don't if it will charge extra to activate the program
in another computer. Thanks so much!
