Getting Started with MC56F80000-EVK

1. Create new project
   1. Click File → New → Bareboard project, or click the tool bar New icon and select Bareboard project, then click Next
   2. Enter the desired project name in the Project name field. Select the Use default location checkbox by default, the generated project will stored at current workspace location. Then click Next
   3. In the device page, expand the tree control and select 56800/E (DSC) → MC56F80xxx → MC56F80748, then click Next
   4. In the Connections page, select the desired connections. If the on-board debugger is used, select P&E USB Multilink Universal [FX] / USB Multilink. Then click Next
   5. In the Language page, select C language, then Click Finish, the IDE create the project
   
2. Modify the stationary and insert your own code

   There are three files in the new project that are most in need of modification: main.c, Flash_config.c and Cpu.c.

   1. Cpu.c contains the routine executed before main. Expand the project folder and select Project_Settings → Startup_Code → Cpu.c, open this file. 8MHz internal clock with PLL is used by default, changing CLOCK_CONFIG to choose other clock source
   2. Flash_config.c contains an array variable that configures Flash Configures Field (FCF)
   3. In main.c, delete the unwanted example codes, but keep below two lines
   4. Insert your own codes
3. Build, compile and run the project as described previously

1. Open the MCUXpresso Config Tool
2. Select the Create a new configuration and project based on an SDK example or hello world project radio button from the Start development window. Alternatively, you can select the option by choosing File → New from the Main Menu. Then click Next
3. On the next screen, click Browse… to select the location of the MCUXpresso SDK that you had unzipped earlier, then select Create new project for device MC56F80748. You can then also specify where to store this project and the project name. Then click Finish
4. Click Close and Update Code
5. Click OK

6. A new project is cloned and the Peripherals tool appears as default
7. After configuration, open the project with CodeWarrior. Import, build, and run the project as done in the previous section

Now, let's use the clocks tool that's part of the MCUXpresso Config Tool to change the clock settings.

1. Open the MCUXpresso Config Tool with below two options:
   1. Double click the '.mex' file in the project folder
   2. Open the MCUXpresso Config Tool program, in the wizard that comes up, select the 'Open an existing configuration' radio button, and click Browse… to select the project that you want to open, then click Finish
2. Open the Clocks Tool by selecting Tools→clocks from the toolbar, or by selecting the Clocks button from the menu bar
3. Use the clocks tool to modify the system clock. The template project configures the chip to use internal 8MHz OSC as the clock source, and enables PLL to generate the 100MHz BUS_CLK
4. After configuration, it's time to implement these changes into the project by exporting the new updated clock files that are generated by Clocks tool. Click on the Update Code in the menu bar
5. The screen that pops up will show the files that are changing, and you can click on 'change' to see the difference between the current file and the new file generated. Then click OK to overwrite the new files into your project

Next use the Pins tool that is part of the MCUXpresso Config Tool to show how to add a new GPIO pin to your project to blink an LED

1. Open the MCUXpresso Config Tool:
   1. Double click the '.mex' file in the project folder
   2. Open the MCUXpresso Config Tool program, in the wizard that comes up, select the 'Open an existing configuration' radio button, and click Browse… to select the project that you want to open, then click Finish
2. Open the Pins Tool by selecting Tools→Pins from the toolbar, or by selecting the Pins button from the menu bar. The pins tool now display the pin configuration for the template project
3. Use the pins tool to modify the LED routed pin:
   1. In the current configuration, GPIOC0 and C1 are routed as EXTAL and XTAL(routed pins have a check in a green box next to the pin name, and the functions selected for each routed pin are shown)
   2. Disable OCCS routed pins. Click the green box next to OCCS, in the wizard that comes up, uncheck EXTAL and XTAL, or click the Unroute All. Then click Done. The pins will then be disabled and disappear from the Routed Pins list
   3. Route GPIOF6 as a GPIO for LED D5.

      Option A: Find GPIOF in Peripherals signals window, then click the box next to the GPIOF. And select GPIO6 in the pop-up window, then click Done. The pin will then appear in the Routing details window.

      

      Option B: Add a new row directly in Routing details window, click the peripheral box and select GPIOF, then select GPIO,6 in the signal box.

      
   4. Configure GPIOF6 properties
   5. Now it's time to implement these changes into the project by exporting the new updated files that are generated by the Pins tool. Click on the Update Code in the menu bar
   6. The screen that pops up will show the files that are changing, and you can click on 'change' to see the difference between the current file and the new file generated. Then click OK to overwrite the new files into your project

Next use the Peripherals tool that is part of the MCUXpresso Config Tool to show how to configure a PIT for LED blinking frequency control.

1. Open the MCUXpresso Config Tool:
   1. Double click the '.mex' file in the project folder
   2. Open the MCUXpresso Config Tool program, in the wizard that comes up, select the 'Open an existing configuration' radio button, and click Browse… to select the project that you want to open, then click Finish
   
2. Open the Peripherals Tool by selecting Tools→Peripherals from the toolbar, or by selecting the Peripherals button from the menu bar.
3. Use the peripherals tool to configure PIT0:
   1. Add a PIT by clicking the Add button and select PIT, then click OK
   2. Now PIT0 appears in the components window and it's opened. Change PIT0 configuration as the following picture, PIT0 roll-over interrupt is enabled for GPIOF6 flip
   3. Now it's time to implement these changes into the project by exporting the new updated files that are generated by the Peripherals tool. Click on the Update Code in the menu bar
   4. The screen that pops up will show the files that are changing, and you can click on 'change' to see the difference between the current file and the new file generated. Then click OK to overwrite the new files into your project
4. Import the project into CodeWarrior IDE as done in the previous section
5. Open main.c in the project folder and add the interrupt routine in it by selecting 'Copy to clipboard' and pasting
6. Add the GPIOF6 flip code into PIT0 rollover interrupt
7. Build and download the project as done in the previous section
8. Run the application. You should now see the red LED is flashing
9. Terminate the debug session. Push the reset button SW1, you should now see the red LED starts flashing

With the template modified, you will see the MC56F80000-EVK's red LED blinking.
