Final version of K8055 full demo

August 26th, 2009

After some time i finnaly managed to finish the full demo appication for K8055 board. This is everything i need so i can start now making some projects with the board.

This new version (and last one) has a new custom control, the Joystick control. With this you can control the outputs (digital and analog) with a joystick. It’s just a demo how to control the outputs with a joystick and it’s very easy to change what happens when you use your joystick.

This version also includes some bug fixes, the latest version of the K8055 Velleman DLL and the code has been cleaned a little.

Download here (version 1.2.0.1)

I can say about myself that I’ve seen an impressive amount of stand-up comedy, funny improvisations, excellent comedy TV series… but i really don’t know I missed this show. It’s brilliant, it’s funny… it has everything … it’s WOW !

I highly recommend it. Here is the first episode of the show (and it’s only the beginning)

Sound level meter with K8055 (video)

August 20th, 2009

I have implemented a new custom control in the K8055 Full Demo application that can send signals on outputs (analog or digital) based on the sound input in your microphone.

The control also has a sensitivity track bar witch allow you to make the microphone more or less sensitive to input.

Based on the sound level (and sensitivity adjustments) the program sends signals (you can see the LEDs light up) on a number of channels. So if the sound that is coming into the microphone is 6 the first 6 digital outputs are set (first 6 LEDs light up).

The same thing applies to the analog outputs, but instead of setting the output to ON or OFF it sent the voltage between 0-5V. For example if the sound level is 5 (this means the input in the microphone is around 127) it sends ton the analog channel a 127 signal that translates to 2.5V

Velleman K8055 C# test application

August 19th, 2009

In my attempt to (re)learn electronics and PIC programming I’ve bought a K8055 board from Velleman. I know it’s not good to learn PIC (actually you can’t do it with this board) but all i want initially is to make some simple projects without the headache of  programming the PIC.

K8055

The board comes with source code for C++ and a DLL so you can use it in your project to easly communicate with the board. If you need the library for linux get it from here.

As my C++ skills are … well … let’s just say i haven’t programmed anything in C++ for a long time, I made myself a small program in C#.

PHP Spell Checker

August 18th, 2009

This package can be used to check the spelling of text and get fix suggestions.

There is a base class that defines functions for spell checking.

There are also two classes for checking the spelling of text using either PHP scripts that contain arrays of valid words and grammar definitions, or using the hunspell program.

If the classes determine that there are misspelled words, they may return suggestions for eventual fixes.
