PSoC 4 Pioneer Kit Community Project#02 - CapSense Slider

cy.gul

On the 2nd day of our 100 Projects in 100 Days community effort, I am posting one of the PSoC 4 Pioneer Kit's bundled example projects.

 

This is a very simple yet effective CapSenseRegistered demo that implements a 5-segment slider, like the one available on the Pioneer kit.

Moving your finger across the capacative touch slider on the board, you will observe the multicolor LEDs gradually changing color from red to green. These LEDs are driven by the PWM Component.

 

 

Project Schematic:

    (CapSense Component Customizer - Implementing a Capacitive Touch Slider)



Hardware Connections (all internal to the board, no external connections required):

  • 5-segment Slider - P1[1] - P1[5]
  • Green LED - P0[2]
  • Red LED - P1[6]

 

Software Setup:

  • See steps #1 - #6 from the main post here
  • Main.C - This example project implement simple firmware in the project's main.c as shown below (already completed in the example project). The code implmented scans the CapSense slider, then updates the PWM's PulseWidth with the slider value.

  • Hi Im new to any sort of embedded programming but want to give it a go and get stuck in.

    I have the PSoC 4 pioneer kit and am trying to do these tutorials.

    I have tried to do this one however keep getting stuck.

    I have wrote the source code and built it and programmed it all onto the board with no errors showing up in the creator.

    However I just have a constant yellowish light on and the slider doesnt do anything.

    Was wondering if anyone else has encountered this problem or could suggest solutions.

     

    Cheers in advance

    I had the same problem.  I changed the "API Resolution"  in the "Widgets Config" tab of the Capsense Configuration box after i setup the linear slider and that worked for me.  The default was 100, but as the PWM goes to 255 so I was getting stuck with one light always being mostly on which gave it bright yellowish color.
