Well, saying you're "a little stuck" isn't much of a clue as to how much you understand programming in general.  Have you done the usual tutorials, such as Blink and AnalogInput?
 
Yes, i have done a few of them like the blink and the "Knight Rider" loop

Quote
]Do you know how to hook up multiple LEDs to multiple outputs?
Yes i believe so....i designed this schematic based on the RBB and "Knight Rider" to work as a stand alone POV (but it may well be very floored)


Quote
Do you do any programming on non-Arduino devices or computers?
 
only HTML

Do you understand how numbers are encoded into binary bits?
is this BCD? as in:    
0=0000    
1=0001    
2=0010    
3=0011    
4=0100    
5=0101  

if so I am aware of the theory, but have have 0 experience with application.

]Have you seen the non-Arduino POV kits, such as those that LadyAda sells, so you're familiar with the concepts?
Yes im familiar with the concept and electronics, its just the issue of the code im totally out of my depth with.

For POV, the general idea is to store your "image" into a sequence of columns, and each column should be stored in such a way as to efficiently send them to a column of LEDs all at once.  Finally, the main loop of your program should just start pushing out your image, one column at a time, through the whole pattern.


Code:
........    B00000000    0x00
.****...    B01111000    0x78
...*.*..    B00010100    0x14
...*..*. -> B00010010    0x12
...*.*..     B00010100    0x14
.****...    B01111000    0x78
........    B00000000    0x00

Can you see the "A"?  Do you see the "A" in the binary bits also?

 smiley yes i see the A  smiley........so B would be

. . . . . . . .   B00000000
********    B11111111
*. . . *. . *   B10001001
*. . . *. . *   B10001001
*. . . *. . *   B10001001
. *** . **.   B01110110
. . . . . . . .   B00000000


but what are the  0x00,  0x78, 0x14 ect. and how would the above code for A or B fit into the sketch, and is it possible to code a full alphabet onto the sketch, but have a command line that you can just quickly adjust to tell it what word to spell?

thank you smiley

Hello guys and girls, am building a 8 led POV, but Im a little stuck when it comes to the programming.

any chance someone can point me in the right direction for a idiots guide?  
(this is my first project with the Arduino so please go slow on me!  :-*)

Cant see a 28pin IC Socket on the Single-Sided Serial Board plans, dose it fit on the PCB plans provided? or do i have to knock up a Ghetto AVR Programmer for post development?

I can only find ELFA or Digikey part numbers for the V2, not the V3 as shown here http://www.arduino.cc/en/Main/PartsSerialV2 yet no parts numbers on the V3 data sheets found here http://arduino.cc/en/Main/ArduinoBoardSerialSingleSided3

if anyone can let me know what the revisions were along with any part numbers, it would be much appreciated.

Hello guys, just wonder if anyone had any knowledge about using XML to control Stepper Motor Drivers?

would like to make vector image files on illustrator, export to svg files, if I am not mistaken. SVG files are easily passable XML files. Which would be turned into motor control commands for a whiteboard vertical plotter.

any help would be apprechiated, and hey it could be fun!  smiley-wink

For what it's worth, running a linear regulator (like the 7805) off of batteries is not a good idea, you're burning off almost half the power from your 9V battery as heat in the regulator.

But if i had only a 9v bat to hand, I could run my BBB?

and how would i attach it?  :-/

Here the manual for BBB says up to 12V are ok: http://www.moderndevice.com/Docs/BBB_RevC_schematic.pdf

can i only use 5v on my BBB, or due to the TO-92 voltage regulator can i use 9v?

That is a parallel port programmer used to burn bootloaders and programs onto the arduino via the 2x3 pin ICSP header

This does not allow you to communicate with the BBB, you have to use serial for that

So while the parallel port programmer is pretty neat it will help you that much

But i can use it just to load sketches onto the BBB? and will it provide power to the BBB or will i need to use the 5v power pack?

Quote
Are you absolutely sure you have a 25pin serial port?
Sorry no, i have a 25pin parallel port and 2 9pin serial ports.

so i can use the Parallel Port Programmer to the ICSP to load sketches (and bootload if i ever need too?)

gnu_linux, are you on commission from wulfden.org?  smiley-wink

i was hopping to make a cable for free out of bits i have floating about, while I wait for my BUB USB adapter.

there has to be something i can make???????

Are you sure you need a 5pin? The BBB has a 6pin header for TTL serial ( usually 90degree male ) but you can replace it if you get the BBB kit version ( I have a bunch )
Yes its a 6 pin, but do i need all 6 if i user another power supply?

i do have the 3x6 female socket  left over from the analogue I/O on the BBB, cant i just use the top row of 6 and on that and solder wires to the 25pin serial? and if so how?

thanks for your posts, was sort of hopping for something using a 25 pin serial port on one end and a 5 pin female header at the the other......any ideas?
