Olimex LPC2148 + Crossworks + Wiggler

it looks slightly brighter on IE. But nothing a normal person would notice or complain about.

I am going to have to find a ribbon cable lol. Even tho i dont need it, its a good idea i have one lol

um.... i was thinking about making a nice little device. I might as well say what it is because i might not be able to make it anytime soon.

Since a SD card is SPI and you can have more than one on the same lines just using separate CS line i was thinking about making a SD Card Cloner or at least a Backuper lol like.

Ill have a 4GB SD Card as the backup drive. And use any other SD 32MB to 4GB as the source. And implement that FATFS or similar library to copy all files from the source to the backup.

Then if wanted copy from backup to another source.

I dont know why anyone would want something like this but i like the IDEA of it
I like having the option to create a backup of files without a PC.

Then i was thinking about a hard drive cloner. But instead of copying files you would have to have 2 identical hard drives and it would clone the entire thing from boot to end.

is it possible to make a huge mistake and not be able to program the LPC2148 again?

Im trying some interrupt code and for some reason i cant debug or program anymore and both my leds are on. How can i force it to erase the entire IC?

Is this fixable?

heh got it working thanks to the fella in the LPC2000 yahoo group. What i had to do was Connect my serial cable for ISP bootloader mode and then erase complete chip with a util like FlashMagic and now im back up!

Ok i finally got a button interrupt good!!

EDIT: I cleaned up the code and added a bunch of comments for all. Also I need more to comment but am tired lol so enjoy this for now

I am going to see if i can setup my own forum so i can keep track of my LPC stuff. I will of course support this forum and be here all the time.

**broken link removed**

Changed the ISR to :

void IRQ_Routine (void) {
      if(MyDat)                       //If MyDat >= 1 then 
        MyDat = 0 ;                   //set it to a 0
      else                            //if not
        MyDat = 1;                    //set it to a 1

      while(!GETBIT(IOPIN0,Btn1));    
      DelayMs(5);                     //5 millisecond delay
      EXTINT = 4;                     //clear interrupt flag
      libarm_set_irq(en);             //re-enable interrupts
}

Wow. You actually paid for a vBulletin license. Classy.

heh i got a deal from a guy who owned the hosting before me. I bought his and then redid it all and then bought a domain. And re registered it in my name smart right lol

Heh i finally changed that top logo
