writing to sd card

claym53

Ok I have the variable to be written to the card set like this:

int value = recbuf[noparse][[/noparse]k]+recbufA[noparse][[/noparse]k];

What is happening is that it is adding the numbers and not putting them side by side...
So I tried to use Concat... like this:

int value = recbuf[noparse][[/noparse]k].concat(recbufA[noparse][[/noparse]k]);

So value = 123456, not 579, but when I do this I get an error:

'This type of expression,"int", is not a valid refrence type in this context.

Please help

Here is the whole program I am working on... In case your curious I'm trying to get these arrays broken apart and put on the sd card, so I can then later read the data from the card and put it back into arrays...

CPU.writePin(CPU.pin2,false); //idle state output pin
CPU.writePin(CPU.pin3,false);

//record

int value· = (recbuf[noparse][[/noparse]k]<<8) | (recbufA[noparse][[/noparse]k]&0xFF);

edit: note that this only works if recbuf[noparse][[/noparse]k] and recbufA[noparse][[/noparse]k] have values 0 to 255

regards peter

claym53

Ok , I tried that:

int[noparse]/noparse recbuf = new int[noparse][[/noparse]128];
recbuf = 234;
recbuf = 134;

int value = (recbuf<<8) | (recbuf&0xFF);
System.out.println(value);

It prints the value as -5498, but I need it to be 234134

Peter Verkaik

If you need to print two values adjacent:
System.out.print(recbuf[noparse][[/noparse]k]);
System.out.println(recbufA[noparse][[/noparse]k]);

To create a string
char[noparse]/noparse buf = new char[noparse][[/noparse]13];
int n = Format.bprintf(buf,0,"%05u",recbuf[noparse][[/noparse]k]);
n = Format.bprintf(buf,n,"%05u\r\n",recbufA[noparse][[/noparse]k]);
buf[noparse][[/noparse]n]=0;
If recbuf[noparse][[/noparse]k] is 123 and recbufA[noparse][[/noparse]k] is 456 then
buf is "0012300456",CR,LF,0

I used %05u to print unsigned decimal values 00000-65535
Without a fixed length of the values you won't be able to split
the string at a later time. If you use %u then
buf is "123456",CR,L,0

The code if have now, records 128 pulses from both channels, plays them back and then records them to data.txt on the sd card. The problem is, say I want to record pulses for like 15 minutes, that wouldn't work because that big of an array would cause the javelin to run out of memory and throw an error. So what I tried to do was as the pulse came in I would just try to write it to the file and not put it in the buffer array. The problem with this is that it takes to long to write to the card and then the pulse timing is off.

So what I want to be able to do is something like this:

while (CPU.pin10 = true) // while button is pressed record

(record pulses and write to card)

}


Here is the code I have now:

You can save 50% of ram used by the arrays, by defining them as char arrays.
Because the pulses are servo pulses, their high periods are 1 to 2 msec.
This corresponds to 115 to 230 ticks of 8.68usec.
recbuf[noparse][[/noparse]i] = (char)CPU.pulseIn(2350,CPU.pin0,true)+10; //record high period
This decreases also the time to store the value since only 1 byte is stored.
Note that the special values -1 and 0 of the pulseIn() are stored as 255 and 0,
so these do not interfere with normal pulse values.

You can record approx. 4 minutes that way.
2 channels * 50 pulses/sec = 100 pulses/sec = 100 bytes/sec
4 minutes = 240 secs = 240*100 bytes = 24kBytes
That still leaves you 8kBytes for code.

Do I also need to declare my arrays as char when I declare them?

int[noparse]/noparse recbuf = new int[noparse][[/noparse]128]; //high periods
int[noparse]/noparse recbufA = new int[noparse][[/noparse]128];

I tried this:

char[noparse]/noparse recbuf = new char[noparse][[/noparse]128]; //high periods
char[noparse]/noparse recbufA = new char[noparse][[/noparse]128];

But I get errors...

Peter Verkaik

When you declare the arrays as char arrays,
you must cast the pulsIn result to char.

static void main() {
char[noparse]/noparse recbuf = new char[noparse][[/noparse]128]; //high periods
char[noparse]/noparse recbufA = new char[noparse][[/noparse]128];
CPU.writePin(CPU.pin2,false); //idle state output pin
CPU.writePin(CPU.pin3,false);
//record
for (int i=0; i<128; i++) { //record 128 pulses
recbuf[noparse][[/noparse]i] = (char)(CPU.pulseIn(2350,CPU.pin0,true)+10); //record high period
recbufA[noparse][[/noparse]i] = (char)(CPU.pulseIn(2350,CPU.pin1,true)-10);
CPU.pulseOut(recbuf[noparse][[/noparse]i]&0xFF,CPU.pin2); //high pulse out
CPU.pulseOut(recbufA[noparse][[/noparse]i]&0xFF,CPU.pin3);
System.out.println("record: "+recbuf[noparse][[/noparse]i]+" - "+recbufA[noparse][[/noparse]i]);
CPU.delay(100); //wait 10msec·· 100
}
CPU.delay(10000); //wait some time
Terminal.getChar();
for (int i=0; i<128; i++) {··· //playback (on another pin)
CPU.pulseOut(recbuf[noparse][[/noparse]i]&0xFF,CPU.pin2); //high pulse
CPU.pulseOut(recbufA[noparse][[/noparse]i]&0xFF,CPU.pin3);
System.out.println("play: "+recbuf[noparse][[/noparse]i]+" - "+recbufA[noparse][[/noparse]i]);
CPU.delay(200); //wait 20msec 200
}

I got this:

"Error: Type java/lang/Character was not found"

Is there a library I need to include or something? and if so where do I get it?

Peter Verkaik

Type char is a builtin type, just like int.
Are you sure you used char, and not Char or Character?

Also check your classpath
Menu Project->Global options
If you installed the Javelin IDE in the default directory, you should have
c:\program files\Parallax inc\Javelin Stamp IDE\lib;
If not, browse to this directory using the button on the right.

regards peter

claym53

Yes, I used char not Char or Character and the classpath is correct.

Peter Verkaik

Can you post your program
as an attachment?

and I'm still getting that error and still confused as to why?

maybee importing the stamp.util.text.* is conflicting with char?

Peter Verkaik

The error is caused by the lines

and
System.out.println("play: "+recbuf+" - "+recbufA);

Change them to
System.out.print("record: ");
System.out.print(recbuf[noparse][[/noparse]i]&0xFF);
System.out.print(" - ");
System.out.println(recbufA[noparse][[/noparse]i]&0xFF);

Ok nevermind, after the recbuf and recbufA needed to be recbuf and recbufA....

Peter Verkaik

You did leave out the array indices for recbuf,recbufA and buf.
The attachement compiles without error.
