- | 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 | ||
