1  Using Arduino / Displays / Re: displaying sensor readings with the nokia 5110 on: January 30, 2011, 04:05:21 am
its very simple actually......

http://www.nuelectronics.com/estore/index.php?main_page=product_info&products_id=12


go to this link and download their pdf which gaves about the pin outs of their product.Then connect the display with the arduino as per their pin outs and use their software library...

i have done this...
i think gaving this display 10$ is very expensive.So try to buy the display of 3310 from the mobile maintenance shop....

I know c  c++ and VB.....i like to study PYTHON, as i have done some small experiments on my symbian mobile with python.....but dont know full details about how to access com port from it(for arduino).....

any tutorial will be appreciated greatly

ok when i connect arduino most time the com port generated in com 30

and if my bluetooth or wifi is on(same switch)
the bluetooth coms that are generated are
com16
com17
com26
com27
com28
com29
com4
com5

i dont know how to control the com port creation...any help on it???
am using HP integrated bluetooth (Broadcomm)

noboby know a solution for this?????????
where are the experts  :-/

In that sense Ubuntu is the best smiley-wink
but i cant take full advantage of programming VB there(comm port) >smiley-sad

My arduino IDE is not starting when my wifi or bluetooth of the laptop is on....
its because of the extra com ports that is created when we connect to internet i think...

could any body can resolve this....am suffering a lot :-[

I have problem with the IDE's because it will not start simply wen my wifi or bluetooth is on.....its so embarrassing....

am using vista...its because of the COM port conflict....any idea how to solve??? ...

i think am starting a post on that problem...

ok am wrong........
is there any way to write programs from any other IDE other than arduino?

I know my program is alone....with out any underlying kernel that make the memory management .....but the program have full control over the memory and can do any at the machine level and also the amount of garbage will be small which could handled...........

but did u think actually my program is alone there???

no its not alone .....because we are using arduino

if we are using direct assembly or pseudo code for the atmega then only it will be alone. smiley-grin

i just want to know if i can do so.....thats all....

i think dynamic memory allocation using the common "new" or "malloc" is mostly needed for small memory...
for example
if we are declaring an array a[200] and only taking 10 locations then rest of the part is wasted..i think u know that cormen. smiley-wink

Is there any way to implement some of the data structures such as linklist,tree,graph or some thing in arduino???

it basically will need pointers and dynamic memory allocation.....

any way????????experts??????????? 8-)
