Dvshade Easy Looks Serial Port

49 thoughts on “ Easy Portable Serial Ports ” Ren says. Purchased less than a month ago by my boss who has no reason to look for a serial port when shopping. Sure enough, there’s that. Serial port is a type of device that uses an UART chip, a Universal Asynchronous Receiver Transmitter. One of the two basic ways to interface a computer in the olden days, parallel ports were the other way. Serial is simple to hook up, it doesn't need a lot of wires.

Frogeraie 18-Feb-13 12:19 18-Feb-13 12:19 I love your project, unfortunately I cannot make it work! I have been trying for quite a while to do something like that (getting Arduino data on the web as well monitoring Arduino from a web page) and I looked at Duino, Noduino, Johnny-five projects to no avail.

I thing your idea to use Wamp is very good. Can you give me some more guidance?

You give a list of libraries required (JQuery, Flot.), do I need to put them in my project directory together with server.js and index.html? In index.html should I change the path and the name accordingly to what I actualy have downloaded?

Thank you for your help. I don't have a netduino yet, but i think the only part that needs changing is the MCU code. In other words we can easily translate my code for Arduino to Netduino compatible. The communication from the MCU to COM PORT is standard serial comms and must be readable by SerialPort on the receiving end. Hence I think the whole thing can still work. If I get the chance to play with Netduino no doubt I will write something about it.

I am currently working on a PIC variant for this project and would be writing my experience about it as soon as it's done. PIC is most widespread in our place because of its generally cheaper implementation. But it's more difficult because there are too many PIC chips available causing confusion.

Bhol dena mujhe ringtone download. Anyway, I will just update this in the future when things are ready. Thanks for the vote! I do think though that this article really needs some updating because a lot has changed since i wrote this.

Udesh Settinayake 28-Jul-12 5:16 28-Jul-12 5:16 Hi, 'Setup the Apache config to point to your working directory and have it serve the index.html for the clients.' I didn't understand this step. Wamp server already has c:/wamp/www directory as the default. I created my working folder inside that www directory and followed your steps. And when I run node server.js through cmd by going to my working directory it's shows as 'info - socket.io started' But when I go to this url working directory]/ It doesn't shows me any data from the serial.

Only just empty potentiometer value and empty graph. I'm sure I did follow all your steps. Don't know what's the problem. I'm using windows 7 OS, WampServer and arduino UNO @ com7. Note: I changed the com3 to com7 also but still it doesn't seems to work for me.

Please help me on this will you. Regards, Udesh. You must make sure your server side js file is running. You must make sure you have the correct port. To verify this make sure to use the arduino programmer and use the same port used to program the arduino.
