4.2 Clone an Example Project Using MCUXpresso Config Tool for 3rd Party IDE

The following steps will guide you through the manipulation of the general-purpose outputs. The example sets up a SCTimer to generate a PWM signal and change a LED brightness.

1. Open the MCUXpresso Config Tool
2. In the wizard that comes up, select the “Create a new configuration based on an SDK example or hello word project” radio button and click on Next

3. On the next screen, select the location of the MCUXpresso SDK . The SDK package must be unzipped beforehand. Then select the IDE that is being used. Note that only IDEs that were selected in the online SDK builder when the SDK was built will be available and click on clone select example. Then select the project to clone. For this example, we want to use the gpio led output project. You can filter for this by typing “ctimer” in the filter box and then selecting the “ctimer_match_interrupt_example” example project. You can then also specify where to clone the project and the name. Then click on Finish

4. After cloning go to the directory you selected and open the project for your IDE. Import, compile, and run the project as done in previous sections
5. You should see the RED and GREEN LED changing back and forth
6. Terminate the debug session

4.3 Use MCUXpresso IDE Pins Tools

Note: Previously, you had to clone an SDK project like in the previous step.

1. Open the pins tool by selecting “ConfigTools” on the top right hand of the file explorer window and then select “ Open Pins”

2. The pins tool should now display the pin configuration for the ctimer project

4.4 Use the Pins Tools to Modify the LED Routed Pin

1. We’ll use MCUXpresso IDE for the rest of the instructions, but the same steps can be done in MCUXpresso Config tools for third party IDEs. In the Pins view deselect “Show dedicated pins” and “Show no routed pins” checkboxes to see only the routed pins. Routed pins have a check in a green box next to the pin name. The functions selected for each routed pin are highlighted in green

2. In the current configuration, GPIO_12_LED_GREEN are routed as the outputs of the CTimer. Let’s add the pin configuration to enable the GREEN LED
3. Select “Show no routed pins” to see the other options. To enable the green LED, search for GPIO_12 and select GPIO_12, 0 under the GPIO column

4. Next configure the GPIO pin as an output in the “Routing Details” window
5. Now it’s time to implement these changes into the project by exporting the new updated pin_mux.c and pin_mux.h files that are generated by the Pins tool. Click on Update Project in the menu bar

6. The screen that pops up will show the files that are changing and you can click on “diff” to see the difference between the current file and the new file generated by the Pins tool. Click on “OK” to overwrite the new files into your project

Note: The clocks and other files may also be tagged as being updated since the header has been changed.


7. The screen that pops up will show the files that are changing and you can click on “diff” to see the difference between the current file and the new file generated by the Pins tool. Click on “OK” to overwrite the new files into your project

8. Let’s add some additional code to the example. Open simple_match_interrupt.c file and add the following macros for the third ctimer output

9. Some additional code to be implemented will be the third ctimer’s callback, this can be copied from ctimer_match1_callback and modify the content to match2. To be able to visually identify the new ctimer, we will remove one of the previous ctimers as shown

10. The main function will need to include the initialization and set up of the Ctimer

11. Build and download the project as done in the previous section
12. Run the application. You should now see the Green, Blue and RED LED blinking back and forth
13. Terminate the debug session
