Testing out the LPC1343 board

Installing the toolchain

Installed YAGARTO according to MicroBuilder's tutorial http://www.microbuilder.eu/Projects/LPC1343ReferenceDesign/LPC1343Toolchain.aspx

All good!

Install IDE

Go to http://www.codelite.org/ for download I didn't install UnitTest++

Also downloaded the CodeBase http://www.microbuilder.eu/Projects/LPC1343ReferenceDesign/LPC1343CodeBase.aspx

Followed the Codelite tutorial http://www.microbuilder.eu/Projects/LPC1343ReferenceDesign/LPC1343CodeLiteTutorial.aspx

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
  systemInit();

  while (1)
  {
    #ifdef CFG_INTERFACE
      // Handle any incoming command line input
      cmdPoll();
    #else
      // Toggle LED @ 1 Hz
      systickDelay(1000);
      if (gpioGetValue(CFG_LED_PORT, CFG_LED_PIN))  
        gpioSetValue (CFG_LED_PORT, CFG_LED_PIN, CFG_LED_ON);
      else 
        gpioSetValue (CFG_LED_PORT, CFG_LED_PIN, CFG_LED_OFF);
	
	// Say Hello to my little friend!
	printf("hello World!\n\r");
	
    #endif
  }
}

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

Adding analog

You can read from the ADC converter (it can do up to 200ksps) quite easily!

#include "sysinit.h"
#include "core/adc/adc.h"

int main (void)
{
  // Configure cpu and mandatory peripherals
  systemInit();

  // initialize the internal ADC
  adcInit();

  while (1)
  {
    #ifdef CFG_INTERFACE
      // Handle any incoming command line input
      cmdPoll();
    #else
      // Toggle LED @ 1 Hz
      systickDelay(1000);
      if (gpioGetValue(CFG_LED_PORT, CFG_LED_PIN))  
        gpioSetValue (CFG_LED_PORT, CFG_LED_PIN, CFG_LED_ON);
      else 
        gpioSetValue (CFG_LED_PORT, CFG_LED_PIN, CFG_LED_OFF);
	
	// Say Hello to my little friend!
	printf("Analog 0: %d\n\r", adcRead(0));
	
    #endif
  }
}
