Good one. Reminds me of college days.

Visit to MASTER's By Microchip in Banglore

2010-11-28T00:20:00.000-08:00

On 25th to 26th November, i attended a conference cum hands-on-workshop by Microchip in Banglore. It was a good workshop where i learnt some new concepts. The topics that i attended were related to dsp and power supply design. Lectures were mainly based on the Microchip product utilisation in different fields. But i must say that really Microchip is in competition. You ask anything they have the solution. It was an good and quite knowledgeable experience. Lets see how much io can utilise from this workshop. However, i got one more way to think creating any system.

Creating permanent link to Your USB physical device in ubuntu

2010-10-25T01:05:00.000-07:00

Whenever you plug in your USB device to the system it has been assigned a node in /dev directory e.g. /dev/ttyUSB1, /dev/sda1 etc.. For me problem came when i tried to use a evdo to connect to Internet. whenever i insert the evdo it creates three nodes in /dev directory with name ttyUSB"number". Now this "number" is dynamic. Dynamic means it can vary from time to time when you plug and un-plug your device. So you have to always take care of this thing that which node is actually for evdo. So what is the solution?? one solution is to use wvdial which automatically recognizes your device and starts the connection but here i'm looking for some other idea which will just create a dedicated node for my device.

The hero is UDEV!!!

I dont know much about UDEv but there are so many sites which gives a good description on udev and its use. I'm mentioning some of them at the end of this post. In udev we can create some rules that can define our devices name, links, ownership, group etc.. Here, i'll tell how to create a dedicated node for our device. rules.d The folder where we are going to put our rules is /etc/udev/rules.d/ . Here, u'll find many rules created for other devices. One more thing that u'll notice here is files starting with numbers. These numbers indicate the priority. So, what we'll do, we chose a name such that it should be executed at the end of all the rules execution such that our rules will be the final. So, we'll give name starting with alphabets with extension ".rules". e.g usb-names.rules For writing the rules, the basic idea is to first locate your device and then give any name or apply any setting. So how to locate our device?? I have a EVDO which gets registered to /dev/ttyUSB0,1 and 2. It creates three interfaces out of which only the first interface connects to Internet.

Locating our device:

udevadm info -a -p $(udevadm info -q path -n /dev/ttyUSB0) Output of this command gives a hierarchal description of the device. This output is even good for them who have interest in device drivers. Output for this command for my device is:

Udevadm info starts with the device specified by the devpath and then walks up the chain of parent devices. It prints for every device found, all possible attributes in the udev rules key format. A rule to match, can be composed by the attributes of the device and the attributes from one single parent device.

looking at device '/devices/pci0000:00/0000:00:1a.1/usb4/4-2/4-2.4/4-2.4:1.0/ttyUSB0/tty/ttyUSB0':

KERNEL=="ttyUSB0"
SUBSYSTEM=="tty"
DRIVER==""

#Parent node of above device
looking at parent device '/devices/pci0000:00/0000:00:1a.1/usb4/4-2/4-2.4/4-2.4:1.0/ttyUSB0': KERNELS=="ttyUSB0"
SUBSYSTEMS=="usb-serial"
DRIVERS=="option1"
ATTRS{port_number}=="0"

#Parent of above device
looking at parent device '/devices/pci0000:00/0000:00:1a.1/usb4/4-2/4-2.4/4-2.4:1.0':
KERNELS=="4-2.4:1.0"
SUBSYSTEMS=="usb"
DRIVERS=="option"
ATTRS{bInterfaceNumber}=="00"
ATTRS{bAlternateSetting}==" 0"
ATTRS{bNumEndpoints}=="03"
ATTRS{bInterfaceClass}=="ff"
ATTRS{bInterfaceSubClass}=="ff"
ATTRS{bInterfaceProtocol}=="ff" ATTRS{modalias}=="usb:v12D1p140Bd0000dc00dsc00dp00icFFiscFFipFF"
ATTRS{supports_autosuspend}=="0"
ATTRS{interface}=="Data Interface"

looking at parent device '/devices/pci0000:00/0000:00:1a.1/usb4/4-2/4-2.4': KERNELS=="4-2.4" SUBSYSTEMS=="usb"
DRIVERS=="usb"
ATTRS{configuration}==""
ATTRS{bNumInterfaces}==" 4"
ATTRS{bConfigurationValue}=="1"
ATTRS{bmAttributes}=="a0"
ATTRS{bMaxPower}=="500mA"
ATTRS{urbnum}=="7479"
ATTRS{idVendor}=="12d1"
ATTRS{idProduct}=="140b"
ATTRS{bcdDevice}=="0000"
ATTRS{bDeviceClass}=="00"
ATTRS{bDeviceSubClass}=="00"
ATTRS{bDeviceProtocol}=="00"
ATTRS{bNumConfigurations}=="1"
ATTRS{bMaxPacketSize0}=="64"
ATTRS{speed}=="12"
ATTRS{busnum}=="4"
ATTRS{devnum}=="7"
ATTRS{version}==" 1.10"
ATTRS{maxchild}=="0"
ATTRS{quirks}=="0x0"
ATTRS{authorized}=="1"
ATTRS{product}=="HUAWEI Mobile"

Here, you can see the desription about your device. To distinguish my EVDO device, information that we can take is converted to bold letters in above outout. So, as we know the things that we can use to discriminate our device, it's time to write our rule

Writing rules:

create a file with name of your choice in /etc/udev/rules.d/ with .rules extension. I chose usb-names.rules .
gedit usb-names.rules

DRIVERS=="option", SUBSYSTEMS=="usb", ATTRS{bInterfaceNumber}=="00", SYSYFS{../idVendor}=="12d1", SYSFS{../idProduct}=="140b", NAME="INTERNET"

save your file and exit.
Now, to implement this rule, use following command

udevadm trigger
See your device in /dev directory u'll find that instead of /dev/ttyUSB0 your device is connected with name /dev/INTERNET. I've only changed the name of first interface out of three interfaces that is created by my EVDO. because it's only used to connect to internet. If you device only creates single node you can safely remove ATTRS{bInterfaceNumber} parameter.
To add more attributes you can directly copy paste the ATTRS from your device description. Like i can direcly take ATTRS{product}=="HUAWEI Mobile" description to match my device.
Even, if just want to create link to your device you can write like this

DRIVERS=="option", SUBSYSTEMS=="usb", ATTRS{bInterfaceNumber}=="00", SYSYFS{../idVendor}=="12d1", SYSFS{../idProduct}=="140b", SYMLINK+="INTERNET"

This will create link for your device.

This much for this post. I think this post will help you guys. If u get any query feel free to write.

Life @T Hyderabad

2009-10-25T18:57:00.000-07:00

So this time this post is from hyderabad.... it's good to write a column on lyf at "somewhere" becoz to write a column on it u hav to be at somwhere... and now for me this somwhere is HYDERABAD...

so starting with the reason, why am i here??? this is the cdac, hyderabad which i joined last month i.e. 9th of sept.. diploma in embedded system is the course which im pursuing right now.... the course that i ever wanted to do.... after completion of month i even found it really that thriiling and exciting as i was thinking abt it... being one among strength of 75, it feels gud to realise that im in a govt organisation which develops so many gud and benificial ideas for our country and PARAM (the superfast parallel computer), Bharat Operating System etc... are some on uncountable list of cdac work.... the lecturer and teachers are those who research here.... thats why the lectures here at cdac is different from our college lectures... this lectures got the flavor of experience, practicallity and understandibilty... till now we are done with c, c++, java, data structures, data communication, operating system, AVR 8bit microcontrollern and Unified Modeling Language.... man i didnt count before that it's like completing one whole semester in a month... from today onwards we are goin to look on RTOS.... wooooo, it's gonna be xciting...

but one more thing i learnt here is that u r not goin to be spoon fed.... u'lll be shown the way but u wont be accompanied on the way... u can get help, support but u hav to go on ur own.. the reason is that if we get so much dependent on the lecturers, it cud be difficult for us in the future... we sud develop on our own... then only we can become independent to fight in today's scenario....

apart from studies, lyf at hyerabad is not that xciting.... livin alone in a single room paying 3100 and eating one of my lyf's horrible food, it's not that gr888.... people here dont understand u and u cant understand them, it's like programin 8085 using avr instructions... even food are getting worse day by day... just imagine how can u eat rice in breakfast,in lunch and in dinner... u hav to eat a daal which has so many leaves and many other external friends delibrately added to make it delicious but on my part it gets worse.... so without going into deep of my heart .... lets end up here giving 6 stars out of 10 for lyf at HYDERABAD...

Kitabo k Panno ko Palat k sochta hu, Yu Palat jaye meri zindgi to kya baat hai,

khwabon me Roz Milti hai jo Hakikat me Aye to kya baat hai,
kuch Matlab k liye dhundte hai mujko, bin matlab jo aaye to kya baat hai,

katal kr k to sab le jayenge dil mera, koi baaton se le jaye to kya baat hai,

jo sharifo ki sharaft me baat na ho, 1 SHARABI keh jaye to kya baat hai,

apne rehne tak to khushi dunga sabko, jo kisiko meri maut pe khushi mil jaye to kya baat hai..
