Hey All,

Sorry I'm only posting now....a bit buzy.

It worked....an it made me simplify my code even more.

Thanks all.

Hey Paul and Liudr,

Thanks a mil for the advice. (ah yeah, i saw the double lcd inclusion) I will definitely follow it. Will let you know how it went.

May take a couple of days.

          
I need some advice on coding something is strange
I have written couple of apps using the LCD and never had this issue
i'm not sure if my app is getting too big for the Uno or not
but there seems like i reach some point then the arduino does funny things
but as soon as i remove 1 line for the LCD
it works. There are other lcd.Print code lines which all work fine, but I really do not know what is going on.

Perhaps it's my structures or the way i initialize them. Can someone help?

Heard of anything like that?

You will see i have attached two files. one with code that is working, the other with code that is not working. The only difference is in the Non Working code i enable the following line   
 
        lcd.print("Loading done..");

But the Arduino resets before this line and restarts.

Thanks a mil. I will look into it.

Sorry forgot also:
6) All SC's initial baud rate is 9600, then you can get the max baud rate available from the ATR.
7) Atr's are much longer than 4 bytes most of the time. like :
   00 31 C0 71 D6 65 13 0D 01 81 01 83 
 

Hi There,
There  are a few things you need to be aware of with smart cards:
1) Know if the card is just a memory chip or a proper microprocessor card.
2)Smartcards (SC's) have two protocols T0 and T1. The comms from the chip is different for both.
3)Checkout http://www.cardwerk.com/smartcards
4) the bottom two contacts (4 and are not used = RFU
5) Some SC's work on lower voltages than 5v, so just be carefull not to pop the device.

Can anyone tell me how to do Windows xp Command line Compiling and uploading with version 0021?

Hi there,
I want to be able to change the Arduinio / Atmega328 's epprom values whithout changing the scetch / firmware I have uploaded initially. Any ideas?
 .
Forexample, I have uploaded initial values in eeprom positions 10,20 and 40. But at a later stage i want to change these values without having to reload the whole sketch again.
Regards,

Hey Pauls,

Thanks, i removed the include for the WString and it compiled.

Thanks

Hi All,

I have downloaded the new Arduino 0021 version and tried to compile a sketch that is already compiling and working under the Arduino 0018 version.

in this sketch i am using the libraries :
#include <Streaming.h>
#include <WString.h>
#include <EEPROM.h>

The error below is:

d:\My Documents\My Projects\Embedded_Development\Arduino\arduino-0021\libraries\String\WString.cpp:34: error: prototype for 'String::String(int)' does not match any in class 'String'

And many errors follows. I there a new updated version of WString for 0021?

What is the issue here?

Regards,

Thanks :

Thanks, i will have a look

[[glow]AVR libraries directory[/glow]]

Hi there,

I did something stupid. I accidentally deleted my who [glow]AVR libraries directory[/glow]. I can not find it where i downloaded it last. Were can i download it as i want to start using the interrupts on my arduino

Thanks all
