Testing out the LPC1343 board

Installing the toolchain

Installed YAGARTO according to MicroBuilder's tutorial

All good!

Install IDE

Go to for download I didn't install UnitTest++

Also downloaded the CodeBase

Followed the Codelite tutorial

Open Main.c in the root directory under the Workspace tab

Right-clicked on LPC1343_CodeBase and selected Build

That didnt actually work. Went into projectconfig.h and commented out #define CFG_INTERFACE did a Clean & Build. File is now about 3Kb. LED blinks! Hooray!

 Don't make the same mistakes I did, always do a Clean before Build!!!

Adding USB CDC

Now to add some basic printing capability!

int main (void)
  // Configure cpu and mandatory peripherals

  while (1)
    #ifdef CFG_INTERFACE
      // Handle any incoming command line input
      // Toggle LED @ 1 Hz
      if (gpioGetValue(CFG_LED_PORT, CFG_LED_PIN))  
        gpioSetValue (CFG_LED_PORT, CFG_LED_PIN, CFG_LED_ON);
        gpioSetValue (CFG_LED_PORT, CFG_LED_PIN, CFG_LED_OFF);
	// Say Hello to my little friend!
	printf("hello World!\n\r");

Do a build and upload the firmware. Connect using a Terminal program at 115.2kbps

You'll see a message every second when the LED changes state
