Hi,

Provided below is a custom implementation of analog Phase-Locked Loop (PLL_scm).

Component implements Phase-Frequency Detector (PFD) as phase comparator and voltage-controlled oscillator based on switched-capacitor delta-sigma modulator. Only few external capacitors and resistors required for low-pass filter. PLL_scm can lock to digital signal, producing one output of the same frequency, and another one of multiplied frequency, both are phase-aligned with the input. The component was designed to operate at low frequencies (10Hz–10kHz), with primary goal of tracking AC power lines (50-60 Hz).

Component was developed as part of RMS detection project. It can be useful for frequency multiplication, quadrature generation, motor control, guitar sound effects, etc.

It was tested using CY8KIT-059 PSoC5 prototyping kit. Several demo projects are provided.

Component Major features:

   Implements analog PLL using Type-II Phase Frequency Detector.

   Uses 1st-order delta-sigma modulator as VCO.

   Primary output is locked in both frequency and phase.

   Secondary output for multiplied frequency.

   Output for optional lock detection.

   Does not consume CPU.

Attached archive contains component library, component datasheet and several demo projects for PSoC5. Please read installation instructions in the readme.txt.

The component provided as-is, no liabilities. It is free to use and modify.

Hi everyone!

I want to share this project I'm working on using a CY8CKIT-050 (PSoC5-LP) to integrate a SSD1963 Solomon LCD controller and a XPT2046 Touch controller with uGUI library. I builded the SSD1963 and XPT2046 drivers and it's working very well.

GitHub - AndresNavas/PSoC5_uGUI_Sample: Sample and Test project of uGUI library in a PSoC5-LP Kit using a SSD1963 Solomo…

I created this project because there's not or really few information about this LCD and Touch controllers with PSoC and those panels are very neat and cheap to use it with cool projects!

Please feel free to use it, share it and improve it.

Don't hesitate to share your thoughts and feedback about it.

Next Improvement: To integrate SDCard for logging data and read Images to display!....

記事では紙面の関係で動作時の写真やプロジェクトが省略されていますのでこちらに置いておきます。

Because of the page real estate the working "picture" nor "project" were not included in the article,

so I put them here 😉

追伸：写真を見直してみて、測定電圧が正確ではないかもしれないことに気が付きました。

　　　まぁ、サンプルということで・・・

P.S.: Seeing the picture again, I noticed that the displayed value may not be accurate.

         But this is a "sample" anyway...

Hi,

Although the "Mission" list suggests to upload binary, I could not figure out where to put one.

So I upload it here. If this is not an appropriate place, please let me know where to put it.

This is the first demo sample binary of mine, a simple maze project using CY8CKIT-044

and  Adafruit 2.8" TFT Touch Shield.

https://www.adafruit.com/product/1651

It utilizes the KXTJ2 accelerometer on CY8CKIT-044 via I2C and

the 2.8" TFT via SPI.

The start point is upper-left and the goal is lower-right.

You can modify the maze by editing "maze.h."

Attached below is basic demo of polyphonic piano using PSoC5 (CY8KIT-059) as processing unit and MIDI Keyboard as input.

This is very basic demo to demonstrate interrupt-driven DDS technique with signal output to 8-bit VDAC. The project is heavily using CPU and interrupts (Arduino-style) and doesn't have  any "advanced" features (DMA, etc), but it is good for introduction.

Attached are: project demo, project screenshots, related Cypress application note and YouTube video.

Hi All,

Attached is my Thermistor Calculator component ("myThermistor"). It calculates thermistor temperature from the resistance, similar to the Creator's stock Thermistor component. Calculated temperature returned as float-precision value with accuracy approx. 0.001 degC. Calculation speed is about 14-15x times faster than stock Thermistor component (formula-based) taking about 1100 CPU cycles.

The component was developed for fast TEC control, where accuracy, speed and wide temperature range were important. Attached archive contains the workspace bundle of the demo project, datasheet, screenshots and reference materials. Tested on PSoC5LP.

Hi,
I am uploading a library of small off-chip components for annotation of the CY8CKIT-059 PSoC 5LP Prototyping Kit.

The KIT-059 component shows all on-board capacitors and pins with direct connections to the OpAmps, DACs, SARs, I2C, UART, LED and XTAL. It helps visualizing ports and pins and making connection diagrams for CY8CKIT-059 Prototyping Kit.

The accompanying library contains few small-sized off-chip annotation components (resistor, capacitors, OpAmps, DAC, etc.). The components are about 50% smaller than their stock analogs, allowing for tighter schematic placement.

The demo project shows all-analog PID control of the levitationg globe, implemented in CY8CKIT-059 PSoC 5LP Prototyping Kit, with annotation diagram created using KIT-059 component.

Attached archive contains component library, a demo project and enlarged picture of the Prototyping Kit. Last tested under Creator 3.3 CP3.

regards,

New version of the Annotation Library (v1.0) is available for download in the Community Code Examples section:

PSoC Annotation Library v1.0

Please note that the Library structure has been re-worked entirely, so that old components (Resistor, Capacitor, etc. will not upgrade). The KIT-059 will update OK.

I recommend to use v1.0 of the Library for new projects, while keeping old projects as-is.
