Project Creation:

• Open PSoC Creator.

• Go to File > New > Project.

• Choose the target device: PSoC5LP CY8CKIT-050 (CY8C5868AXI-LP035 chip).

• Select "Empty Schematic" and name the project Full_LED.

Hardware Configuration:

• Go to the Component Catalog on the right side of the screen, search for the following components and drag them to the TopDesign schematic:

  • PWM

  • SAR ADC

  • Clock

  • Logic Low

  • Digital Input Pin (three times)

  • Analog Pin

  • Digital Output Pin

  • Character LCD

  • Interrupt (twice)

Component Configuration:

• Double-click on the Analog Input Pin, rename it to "Potar", and choose High Impedance Analog drive mode.

• Double-click on a Digital Input Pin, rename it to "SpeedSW2", and choose Resistive Pull Up drive mode. Uncheck HW connection and set Interrupt mode to Falling edge.

• Double-click on another Digital Input Pin, rename it to "BrightSW3", and choose Resistive Pull Up drive mode. Uncheck HW connection and set Interrupt mode to Falling edge.

• Double-click on the remaining Digital Input Pin, rename it to "Reset", and choose Pull Up drive mode. Uncheck HW connection.

• Double-click on the Digital Output Pin, rename it to "LED", choose Strong Drive mode, and set the initial drive state to Low.

• Double-click on the ADC component, rename it to "ADC", set the resolution to 8 bits, the conversion rate to 100000, the input range to Vssa to Vdda (Single Ended), and choose internal Vref as the reference source.

• Double-click on the PWM component, rename it to "PWM", and set PWM mode to one output.

• Double-click on the Clock component and set the frequency to 100 Hz with ±5% tolerance.

• Double-click on the LCD component and set it up as a 2x16 character display.

• In the workspace explorer, double-click on Pins under Full_LED.cydwr and set Port to:

  • P6[3] for LED

  • P6[5] for Potar

  • P2[6:0] for the LCD

  • Appropriate ports for SpeedSW2, BrightSW3, and Reset.

• Rename the interrupt components to "Speed_Int" and "Bright_Int".

Programming and Results:

• Double-click on main.c in the workspace explorer under source files.

• Add the following code to control the speed and brightness of the blinking LED:

• Build the design by clicking on "Build" or pressing Shift+F6.

• Verify and resolve any warnings or errors.

• Connect the PSoC 5LP to your computer using the USB cable.

• Click on "Program" or press Ctrl+F5 to upload the code to the PSoC.

• Adjust the potentiometer to see the changes in the LED's speed and brightness and display the values on the LCD.
