| + | ====== 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** | ||

| + | 0 errors, 0 warnings | ||
| + | </file> | ||
| + | |||
| + | 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! | ||
| + | |||
| + | <code> | ||
| + | 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 | ||
| + | } | ||
| + | } | ||
| + | </code> | ||
| + | |||
| + | Do a build and upload the firmware. Connect using a Terminal program at 115.2kbps | ||
| + | |||
| + | {{:lpchello.gif|}} | ||
| + | |||
| + | 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! | ||
| + | |||
| + | <code> | ||
| + | #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 | ||
| + | } | ||
| + | } | ||
| + | </code> | ||
