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]

HW Package 

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 !

Package

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.

Package

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).

Enjoy!

Package 

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 !
