4.1 Clone an Example Project from MCUXpresso IDE

The following steps will guide you through the manipulation of the general-purpose outputs. The example sets up a CTimer to generate a PWM signal and change between two LEDs.

  1. Find the Quickstart Panel in the lower left-hand corner and click on Import SDK example(s)
  2. Click on the FRDM-MCXA156 board to select that you want to import an example that can run on that board, and then click Next
  3. Use the arrow button to expand the driver_examples category, then expand the ctimer examples, click on the checkbox 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 frdmmcxa156_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. The example sets up a CTimer to make RED and GREEN LED changing back and forth.

  1. Open the MCUXpresso Config Tools
  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 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. Click on "Clone the selected example for a board or kit". Then, select the project to clone. For this example, we want to use the CTimer match interrupt 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, PIO3_12 and PIO3_13 are routed as the outputs of the CTimer. Let's change the pin configuration and add the BLUE LED

  3. Modify the CTimer output pin PIO3_12 as GPIO and output Logical 1 to disable RED LED

    Modify the CTimer output pin PIO3_13 as GPIO to drive GREEN LED

  4. Select "Show no routed pins" to see the other options. To enable the BLUE LED, search for P3_0 and select GPIO3,0 under the GPIO column
  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. Note: The clocks and other files may also be tagged as being updated since the header has been changed.

  7. Let's add some additional code to the example. Open the simple_match_interrupt.c file and add the following macros to initialize the BLUE LED and GREEN LED
  8. Modify the CTimer callback array as below
  9. Add the macro to enable the use of the LEDs, instead of the CTIMER output, so that we can visualize the behavior on the board easily
  10. In the main function, let's reset the GPIO3 peripheral, to ensure it is ready to use
  11. Build and download the project as done in the previous section
  12. Run the application. You should now see the GREEN and BLUE LED blinking back and forth
  13. Terminate the debug session

5. MCUXpresso Developer Experience

Check out each of the following sections to learn about the ecosystem provided for flexible prototyping and development. In the video below, we will introduce you to the FRDM platform, the full-featured EVK and the compatible shields for extended capabilities. In addition, we will walk you through our Application Code Hub portal where we provide numerous application examples through NXP's GitHub.

5.1 FRDM Platform, Full Feature EVK and Shields

For quick prototyping platforms, we offer both the low-cost FRDM platform and the full-featured EVK.

FRDM Development Boards come with standard form factor and headers, easy access to MCU I/Os, onboard MCU-Link debugger and a USB-C cable. Our full features evaluation kits include extended I/Os and interface access, extendable with WiFi and additional MCU-Link features. There are also many compatible Click Boards and/or Arduino Shields. For those that are supported with an Open CMSIS Pack example may be available on ACH, but if not many of them are easy to use via serial interface like I²C, SPI and UART, for which we provide drivers with examples in the MCUXpresso SDK.

5.2 Application Code Hub

The Application Code Hub further enhances our MCUXpresso Developer Experience by giving developers an interactive dashboard to quickly locate software. Visit the ACH  today to start exploring or discover additional details and benefits of the new interactive Application Code Hub. Software accessible from Application Code Hub is located in NXP’s GitHub repository  so, it can be easily accessed and cloned from that location directly.

5.3 Demo Walkthrough

The following demo walks us through importing a project from ACH using a system based on the FRDM platform with a motor control shield and a low-cost LCD. Although your evaluation board may differ from this system, the following steps can be replicated and used for all supported platforms.
