LAB 3: Debugging using MCUXpresso

LAB SECTION: A B C D E F G H I J K L M N O P
OBJECTIVES:
1. To be able to EXPORT an MBED program to MCUXpresso.
2. To be able to IMPORT the program into MCUXpresso.
3. To be able to RUN the program in MCUXpresso.
4. To be able to TROUBLE SHOOT your program by TRACING, Checking Variables, Setting
Breakpoints, etc.
Please WATCH THIS VIDEO and then:
1. Setup MCUXpresso as shown. Then WATCH THIS VIDEO to see how to Trace code in MCUXpresso
2. Make sure you are signed into your MBED ACCOUNT.
3. Click on THIS LINK to download BLINKING_LED that can be Compiled and Downloaded using
MBED onto your FRDM-K64.
4. Compile and download it onto your FRDM-K64 and make sure it works.
5. Click on THIS LINK to download BLINKING_LED_COPY.
6. Export it from MBED to your Downloads folder.
7. Import it into MCUXpresso from your DOWNLOADS folder.
8. Click on the .cpp file and then select the BLUE BUG to download it to your board.
9. RUN it by hitting the ARROW button on the debugger, and make sure that it works.
10. Click on THIS LINK to get the BLINKING_LEDS program. Notice that it has the library needed
for MCUXPRESSO.
11. EXPORT this program to MCUXpresso, and make sure that it runs in MCUXpresso.
12. Go BACK to MBED (remember to disconnect and reconnect the cable -no RESET BUTTON).
13. CLONE the BLINKING_LEDS program and change the MBED Library to the one (Documenation
not ready).
14. Compile it and download it to DAPLINK, and make sure it works.

When you declared the unsigned char ARRAY name, were all elements of the array preset to
some default value? __________
In what type of MEMORY (ROM, EEPROM, RAM, FLASH) are variables and arrays stored ?
___________
In this program what character is put into the ARRAY when the ENTER key is pressed? ______
When dealing with STRING arrays, what is the terminating character ? _______
17. After exiting MCUXpresso, and returning to the MBED COMPILER, what must you do before you
can download any other files to the FRDM-K64?
