IRDA JOY V2.1

 

Here is the final IRDA Joy interface.

V2.1 Updates

* Changed a few components to use 3V power supply

* Added a power switch and a status led

* Fixed a random behavior

* Removed 20ms tempo between each byte frame

* Allow USART (debug) or IRDA mode

The attached IRDAJOY-V2.1-hw.7z file contains schematics.

The attached IRDAJOY-V2.1-sw.7z contains source and hex files to program the PIC. All other details are in the README.txt file.

 

To use this interface with your PSP, you need specific PSP firmware and software. Go to the following link: [http://zx81.zx81.free.fr/serendipity_fr/index.php|http://zx81.zx81.free.fr/serendipity_fr/index.php|fr]

Prototyping board for PIC16F84/16F628

This simple board can be used to do some prototyping, to develop and debug applications based on 16F84/16F628 PIC.

It contains all the necessary components such as crystal, capacitors, I/O, serial interface. So, there is no need to wire everything each time you want to practice PIC programming ! You can quickly test your piece of code.

 

NOTE:

This board cannot program the PIC. You should use a dedicated external programmer !

 

Caracteristics

• PIC 16F84/16F628
• 11 I/O configurable ports d'E/S configurables (jumpers)
• Ouput ports connected to LED
• Input ports connected to dip-switchs
• Serial RS232 or TTL port avec with 9 pin connector. RX/TX pins are using PA0 and PA1 PIC ports
• Power jack to be used with an external power supply or a battery pack (4.5V battery for example)
• Extra power connector to connect other boards
• Removable Crystal

 

The attached file contains all the necessary information to make you own prototyping board.

Have fun !

Temperature logger

 

The purpose of this project was to use a nice and cheap LCD display originally used in a Nokia cellphone.

This project is a small thermometer used to display 2 temperatures (in & out) every 2 seconds.

Le montage présenté ici est un petit thermomètre autonome, permettant d'une part d'afficher toutes les secondes deux températures (intérieure et extérieure) et d'autre part, de visualiser sur deux courbes distinctes, les 72 dernières températures, prises toutes les 5 minutes.

Principales caractéristiques:

• Afficheur graphique 84x48 (LPH7779)
• PIC 18LF452 en boitier TQFP (pas facile a souder mais tellement plus petit !)
• Capteurs de température Dallas gérés par protocole 1-Wire
• Alimentation par deux piles 1.5V
• Il se loge dans une petite boite en plastique contenant a l'origine des vis.

Le package en pièce jointe contient le PCB (format Eagle 5.0), le typon 600dpi, les sources et projet MPlab pour le Pic.

C++ Maze generator

 

This application is used to generate random mazes.
The attached package contains the source code. The implementation uses my own graphical library (Gfx).

Cell identification in an hexagonal mesh

 

 

This C++ application is used to demonstrate how to quicly identify a cell in an hexagonal mesh.

The algorithm is only based on line equations which describe the hexagonal mesh. It is fast and simple.

The attached package contains the source code for two different graphical implementations. The first one is made with the Gtk library and the other with my own small library (Gfx).

The "Schemas" directory contains few quick draws to illustrate how it is done.

Enjoy !

ZX Spectrum emulator for Windows with JUCE library

This 48K Spectrum emulator is a Windows port of the emulator I've made originally for Linux with Allegro library. This time the interface is more comprehensive and has been developped with the fantastic Juce graphical library (http://www.rawmaterialsoftware.com/juce).

• 48K ZX Spectrum
• Snapshots loading / backup on SNA format
• Pause
• Poke memory
• JPG screenshots
• Sound
• Joysticks cursor, kempston, Sinclair 2 interfaces
• Windowed display 320x200

The source files and binary are available in the attache file.

Enjoy!

TI99/4A Toolkit

 

This application can be seen as a set of functions to "emulate" Basic routines of the TI99/4A and as a collection of original Basic games translated in C language.
To be more precise, this application is a TI99/4A framework (main screen, key & joystick management ...) and a set of C routines that can be used to easily translate Basic listings to C code. So, old Basic programs will survive without the need of using an emulator.

Today, there is no integrated Basic interpretor inside. This is in progress.
The application contains only one game : Texas City. The original game comes from "Hebdogiciel N°61" and has been made by Didier Delansey. It is up to you now to add more.
By default, the resolution is 256x192. The executable can be launched with the -scale option. The resolution will be 512x384.

Everything needed to use the toolkit is given in the README file.

Sources and others files are inattached file.

IRDAJOY : IRDA joystick Interface for PSP

This interface allows to connect a digital joystick (Atari) and/or two analogic paddles.

The information are transmitted both on IR (IRDA SIR mode) and serial (TTL).

The interface corresponds to the first release. A little more elaborated version has been made (IRDAJoy V2.1).

This interface is composed of two different boards. One generic PCB (Pic18Proto) equiped with one PIC18F452 microcontroller and one expander on which 1 joystick, or 1 or 2 paddles can be connected.

The attached file contains all the needed things to build your own IRDAJoy.

LM213XB LCD Display Routines

This source code (see attached) contains a set of basic graphical routines for the LCD LM213, based on the HITACHI HD61830 controller.

The routines are usable on a PC (both on Windows or Linux) and the display is connected to its parallel port.

Furthermore, the routines are usable on a PIC microcontroler (not tested).

Enjoy !
