The following steps will guide you through the manipulation of the general-purpose outputs.

  1. Find the Quickstart Panel in the lower left-hand corner and click on Import SDK example(s)
  2. Click on the EVK-MCXNx4x board to select that you want to import an example that can run on that board, and then click on Next
  3. Use the arrow button to expand the driver_examples category, then expand the ctimer examples, click on the check box next to ctimer_match_interrupt_example to select it. To use the UART for printing (instead of the default semihosting), Select UART as the SDK Debug Console checkbox under the project options. Then, click on Finish
  4. Click on the “Click on the “evkmcxnx4x_ctimer_match_interrupt_example” project in the Project Explorer View and build, compile and run the demo as described in the previous section
  5. You should see the GREEN and RED LED changing back and forth
  6. Terminate the debug session

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.

  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 BLUE 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, PIO3_2 and PIO3_3 are routed as the outputs of the CTimer. Let’s add a third Ctimer Match output and enable the Green
  3. Select “Show no routed pins” to see the other options. To enable the third Ctimer Match Output, browse the column for Ctimer and select and output. In this example, we will select, Ctimer4 Match 2 on PIO3_6. Select the item in the Ctimer column to enable
  4. Now, let’s route the Green LED. In the search box type “green” so that the routed pin for this LED is shown. Finally, click the box under the GPIO column. The box will highlight in green, and a check will appear next to the pin
  5. Next configure the GPIO pin as an output in the “Routing Details” window
  6. 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
  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.cfile and add the following macros for the third ctimer output
  9. Add the Green LED functions as well
  10. 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
  11. The main function will need to include the initialization of both the Green LED and the Ctimer
  12. Build and download the project as done in the previous section
  13. Run the application. You should now see the Green and Blue LED blinking back and forth
  14. Terminate the debug session
