RS232 interfacing help
-
HI there!!. I have got a project in which i have to get the data of rfid card through a rfid reader connected through rs232 serial port to the computer and then further manipulate the data...i know i have to use the IO.Ports ...but the thing is i have got so many buks of c# , but whenever the chapter comes about IO.. there is nothing written about IO.ports!!...i just have to read the data from the serial port by detecting the appropriate com port to which its connected.. there are few tutorials but are in bits and pieces and is becoming real hard to understand...please help me refering to some good complete tutorial regarding this..and if you people know some c# book in which IO.Ports is explained then please tell. Thanx in advance!

It isn't covered in much detail because there isn't a whole lot to it! There are articles here which may help (try Serial Communication using C# and Whidbey[^]) There are also many more on other sites: Google is your friend here: http://www.google.co.uk/search?sourceid=chrome&ie=UTF-8&q=SerialPort+tutorial+c%23[^] It is pretty simple: the complexity comes when you actually talk to the device, and no book or tutorial will cover that! :laugh:
Real men don't use instructions. They are only the manufacturers opinion on how to put the thing together. Digital man: "You are, in short, an idiot with the IQ of an ant and the intellectual capacity of a hose pipe."

People who don't want to pay for the LAN hardware and protocol stack processing overheads! :laugh: Seriously, in embedded computing, you can fit RS232 for a few tens of pence, whereas the connector alone for a network cable can cost twice that before you get to the hardware behind the connector. Particularly when you are talking about low volumes.

i couldn't find any rfid reader at low cost, with any ither interface...the one with rs232 was the most common one..thats why i sticked to it...will try to understand the tutorial...will atch back i i encounter problems(which i definitely will! ) :) thnx
