KB 01: Create a PSoC Project using PSoC Creator

Create a New Project

A project in PSoC Creator contains all the source code and files necessary to generate a single output module that can be programmed onto a target PSoC 5LP device.

Start PSoC Creator

To launch PSoC Creator 4.x, follow one of these methods:

• From the Windows Desktop: Double-click the PSoC Creator icon.
  
• Launch PSoC Creator from the Windows Start Menu.
  
• From the Start Menu: Open the Windows Start Menu, search for "PSoC Creator," and click on it.

Create New Project

The first step in creating a design is to use the New Project Wizard in PSoC Creator. This wizard will guide you through the following steps:

• Select the kit, module, or device.
• Select the type of project to create
• Specify the project name and location
• Choose whether to create a new Workspace or add to an existing Workspace

Follow the next steps to open the wizard dialog and configure for a new project:

1. Start a new project by either:
   
   • Click the "Create New Project..." link on the PSoC Creator Start Page.
   • Click the "Create New Project" button in the menu bar.
   • Selecting "File ➤ New ➤ Project ..." from the menu.

   

2. In the Create Project dialog, select one of the following options:
   
   • Target kit: Select a specific kit or the last used kit.
   • Target module: Select a specific module or the last used module.
   • Target device: Select a device family and series, the last used device, or launch the Device Selector.Selecting the kit, module, or device
   Follow these steps to open the wizard and configure a new project:
   
   • If you are using the CY8CKIT-059 Kit and have installed the associated design kit file, select "Target kit" and choose "CY8CKIT-059 (PSoC 5LP)".
     
   • If you have not installed the design kit file or are using another PSoC 5LP development board, click "Target device". Choose "PSoC 5LP" as the chip type and "CY8C58LP" as the chip family, or select "<Launch Device Selector...>". You can then select the specific device you want to use.
     
   • If you choose "<Launch Device Selector...>", the system will display a list of all available PSoC 5LP parts. Select the chip number on your board, and click OK.

     You should probably never need to change this again unless you use another PSoC development board. PSoC Creator remembers the parts you have used in the past.

3. Select the Project Template:
   Next, in the "Select project template" dialog, choose "Empty schematic" as your project template.
   
4. Define Workspace and Project:
   In the following dialog:
   
   • Workspace name: Enter a name for your workspace (e.g., "PSoC5LP"). A workspace is a container for one or more projects.
   • Location: Specify the path where the project will be saved, or click the " Browse" button to select a directory.
   • Project name: Enter a name for your project (e.g., "01_MyFirstPSoC").

   

   PSoC Creator organizes applications into Workspace that can contain one or more projects.

5. Finalize Project Creation:
   Click the Finish button. PSoC Creator will create a new directory based on the location you specified. Inside this directory, it will generate a subdirectory for the workspace, and within that, a folder for the project..
   
6. Once the folders and files are created, the main PSoC Creator window will appear, displaying several panes:
   
   
   • Workspace Explorer: Displays all the files and folders in your project.
   • Schematic Editor (TopDesign.cysch): Shows the top-level schematic for your design.
   • Component Catalog: Lists the available components you can incorporate into your project.
   • Message Panel: Displays build messages, errors, and warnings related to your project.
   This layout allows efficient management of your project resources and design elements.

Device Selector

If you change the PSoC development board, follow these steps to update the microcontroller model:

1. Expand the "Design Wide Resources (.cydwr)" folder in Workspace Explorer and double-click Pins to view the device pin assignments and the current device number.
   
2. Verify that the device number matches the one on your PSoC 5LP board. If not, go to the Project menu, select Device Selector, and choose the correct device.
   
3. Once the correct device is selected, you won’t need to change it unless switching boards.
   

Add/Configure Component

In this step, you will drag Components from the Component Catalog to the Schematic, configure them, and wire them together.

Steps:

1. In the Component Catalog panel, expand the "Digital ➤ Functions" folder and drag a PWM Component onto your TopDesign.cysch.
   
2. Double-click the PWM Component to open the "Configure" dialog, change the Implementation setting to "Fixed Function", and click OK.
   
3. In the Component Catalog, expand the "Digital ➤ Logic" folder, drag a Logic Low '0' Component onto your design, and connect it to the kill terminal on the PWM. Connect another Logic Low '0' to the reset terminal.
   
   
   Select the Wire Tool to connect the logic (or press 『w' as a shortcut). The wire is Green, which means that it is a digital connection.
   
4. In the Component Catalog, expand the "System" folder, drag a Clock Component onto your design, and connect it to the clock terminal on the PWM.
   
5. Double-click the Clock to open the Configure dialog, change the Frequency value to 250 Hz, and click OK.
   
6. Expand the "Ports and Pins" folder in the Component Catalog, drag a Digital Output Pin Component onto your design, and connect it to the pwm terminal on the PWM.
   

Assign Pins and Connect Hardware

At this point, the hardware design is complete. However, the Pin Component must still be associated with a physical pin.

If you did not assign any pins, after you click Generate Application or Build your project from the Build menu, the PSoC Creator will automatically assign the pin to a physical port/pin on the device. To specify a specific pin, use the Pin Editor to assign the pin for the component.

1. In the Workspace Explorer window, expand the "Design Wide Resources (.cydwr)" folder in your project and double-click on the Pins to open the Design Wide Resource (DWR) Pin Editor.
   
2. Pull down the menu in the Port or Pin column and assign Pin_1 to the following pin, depending on the kit you are using:
   

   Cypress CY8CKIT-059 Kit

   Cypress CY8CKIT-059 kit already has a switch and an LED on the board. The switch is connected to port 2, pin 2 (P2[2]), and the LED is connected to port 2, pin 1 (P2[1]). Therefore, for the CY8CKIT-059 Kit, you can assign Pin_1 to P2[1] (or Pin 63).

3. You will notice that many pins have some extra text associated with their port/pin information; for example, P1[2] is also labeled as 「XRES[0]:opt」. These special functions can be associated with the pin for improved performance rather than mandates that a given pin be used for a specific function.

Generate Application

Before you write the code, you must let PSoC Creator generate all the necessary API files to support the hardware components you placed in the schematic earlier. Choose the "Generate Application" item in the Build function to do that.

1. Select the PSoC Creator menu item Build➤Generate Application, or click the icon () on the toolbar.
   
2. If there is no error, PSoC Creator generates several code files under the folder Generated_Source. These are the support files for the components. Do not edit them. They are, in fact, just standard C files, and you could rework them to fit your needs, but the IDE can, and does, frequently regenerate those files, which would wipe out any changes you've made.
   

Write C Code

Add code to the auto-generated file main.c.

1. In the Workspace Explorer panel, double-click the main.c file in your project to open it on the Document window.
2. Add the following function to main():
   PWM_1_Start();

This code assumes that the PWM Component has the default name. If you renamed your PWM Component to something other than the default value, use those names in the _Start() function call.

int main(void)
{
    CyGlobalIntEnable; /* Enable global interrupts. */

    /* Place your initialization/startup code here (e.g. MyInst_Start()) */
    PWM_1_Start();
    for(;;)
    {
        /* Place your application code here. */
    }
}

/* [] END OF FILE */

Program the Device

The programming process is the same for all the development kit boards.

1. Connect the programmer to your PSoC 5LP development board and plug it into your PC with a USB cable.
3. Confirm that the programmer is connected to PSoC Creator through the USB port.
   Select the PSoC Creator menu item Debug ➤ Select Debug Target... A "Select Debug Target" dialog is displayed

4. Click the Program button () in the menu bar.
5. Select your device if the Select Debug Target dialog displays, then click Connect and OK.

PSoC Creator will build your design, generate code, and program the device. When programming is complete, the selected LED on the board will blink; press the Reset button if needed.
