Actualmente estoy montando un sistema mucho m�s sencillo que este para poder controlar con un simple mando de televisi�n universal, cualquier dispositivo mediante un PIC y un receptor de Infrarrojos.

En breve colgar� informaci�n.

The Basic Stamp IR remote interface

My friend and fellow mad scientist Craig Gardner came up with this nifty little project. It is simple and cheap to make, and works really well. It allows the user to send commands to a Stamp using any standard universal remote that can use the Sony protocol. Craig is a Basic Atom guy (don't hold it against him, he's a really nice person ;-)) so I told him I would make a Stamp friendly version. Craig has an article HERE for his version.

His was neatly designed to plug into the servo pins of the Basic Atom equivalent to the Board of Education. Unfortunately, as we discovered, the Stamp BOE has VIN on the servo pins, and the Atom has VDD. I assumed (making a you know what out of you know who) that the BOE had VDD on the servo pins. The smell of scorching silicon is what alerted me to the problem. Oops! A tribute to the durability of the Stamp, it didn't smoke the pin, although it was really hot and refused to program until it cooled off.

So, I decided to make another board design. If I had any 5V zeners laying around, I might have made one that could mount as Craig intended onto the servo pins. But I didn't, so I made it to plug into a breadboard. I also added a jumper to allow user selection of the baud rates 9600 and 2400. I did this so that the device may be used with the BS1 as well as all BS2's.

The function of the device is very simple. Any IR remote than can be programmed to use the Sony protocol will work. The module outputs the device code (TV/VCR/DVD/AUX) and the button pressed, so the device can be used on as many different projects as your remote has devices (usually four). The numeric keys output the number of the key (0 outputs a 0, etc.). The function keys all output unique numbers. Note that not all buttons are available depending on which device you have selected. The VCR setting seems to use most of the keys on the remote. Also note that the first key pressed after the device is powered up does not output what it should. All subsequent numbers are correct. Luckily, all of the numbers so generated make a number different than any of the key codes, so it doesn't cause any problem. This could even be used to let the device know if it has just been powered up or rebooted. I have no idea why it does this.

Construction of the device is also simple. You will need:

1* PIC12F675

1* 8 pin DIP socket

1* T-1 LED

2* 1k resistor, 1/8 or 1/4 watt

1* 10k resistor, 1/8 or 1/4 watt

2* .1uF caps, 6V or higher ( I used E.G. part # G4408A)

1* pair jumper pins and jumper (Optional, see below)

1* IR module

The IR module I used was from the Electronic Goldmine, part #G6042. It is a Vishay/Telefunken TSOP28. There are many units you can use, but the pinout may be different. A 12F675 may be had for free from Microchip through their samples program. This project can basically be made for nothing on a piece of perfboard in 20 minutes. Now that's a good deal! Since many Stamp users will not have access to a PIC programer and the PicBasic Pro complier, pre-programmed PIC12F675's are available for US$10.

As it happened, when Craig gave me one of his units, I was working on a project that has need for a lot of user interface. I was in the process of getting a keypad and decoder set up on a breadboard, but after five minutes of playing with the IR remote, I was hooked, and pulled the keypad off and put it away. Now I have 38 buttons at a cost of one I/O pin, for less than US$6 if all is bought new! And I can use it on four different projects in the same room! It really can't be beat for a simple interface to the Stamp.

The schematic is shown below.

Here is the board layout. Note that the jumper can be omitted if you don't want 2400 baud. You must still put the 10K pullup resistor (R3) in place, or the baud rate may not set itself correctly. The long leg of the LED should be facing R3. The LED indicates the serial data output, and should blink once on powerup. It may be omitted along with it's current limiting resistor (R1) for lower power consumption on battery powered devices.

Here is the board artwork. I use the laser printer method, but as you can see it is simple enough that it could be hand drawn or mounted on perf or proto board. To use the artwork, I recommend printing it out and placing the 12F675 on it to make sure that it is the correct size. I have had trouble with downloaded art work not printing the right size before.

IMPORTANT NOTES: The PIC Basic Pro code

available for download here: http://madlabs.info/assets/images/IR/IRreceiver_1.0.bas

IS NOT compatible with Craig's board!! This is because I added the jumper for the baud rate and changed the board layout.

The HEX file is available: http://madlabs.info/assets/images/IR/IRreceiver_1.hex

for use with any programmer.

The ASM file is available: http://madlabs.info/assets/images/IR/IRreceiver_1.asm

The ASM file is available for use with other compilers. There are a number of cheap/easy programmers out there to build if you don't have one.

Here is a Basic Stamp code example for the unit. It is compatible with either unit.

irPin CON 1 ' Change this to whichever pin you want to use

irBaud CON 240 ' Default baud. Change to 1021 if jumper installed

command VAR byte

device VAR byte

main:

SERIN irPin,irBaud,[device,command]

DEBUG "Device: ", dec device, " / ", "Command", dec command,CR

goto main

Publicado: Lun 01 Sep, 2008 16:51 (GMT 0)

Tengo un proyecto de un Robot que lo quiero comandar con un mando a distancia, con StampBasic ( BS2 ) lo he conseguido con el c�digo siguiente:

C�digo: [Ocultar]

DO ' Main DO...LOOP
 
remoteCode = 0
 
DO ' Wait for end of resting state.
 
RCTIME irsensor, 1, irPulse
 
LOOP UNTIL irPulse > 1000
 
PULSIN irsensor, 0, irPulse ' Get data pulses.
 
IF irPulse > 500 THEN remoteCode.BIT0 = 1
 
RCTIME irsensor, 0, irPulse
 
IF irPulse > 300 THEN remoteCode.BIT1 = 1
 
RCTIME irsensor, 0, irPulse
 
IF irPulse > 300 THEN remoteCode.BIT2 = 1
 
RCTIME irsensor, 0, irPulse
 
IF irPulse > 300 THEN remoteCode.BIT3 = 1
 
RCTIME irsensor, 0, irPulse
 
IF irPulse > 300 THEN remoteCode.BIT4 = 1
 
RCTIME irsensor, 0, irPulse
 
IF irPulse > 300 THEN remoteCode.BIT5 = 1
 
RCTIME irsensor, 0, irPulse
 
IF irPulse > 300 THEN remoteCode.BIT6 = 1
 
' Map digit keys to actual values.
 
IF (remoteCode < 10) THEN remoteCode = remoteCode + 1
 
IF (remoteCode = 10) THEN remoteCode = 0
 
DEBUG CLS, ? remoteCode ' Muestra el codigo en el Debugger del StampBasic
 
IF remoteCode=110 THEN high 2 ' Enciende un LED si se pulsa ese codigo ( mando flecha hacia arriba )
 
LOOP ' Repeat main DO...LOOP

Como esquema he utilizado un simple Receptor de infrarrojos Panasonic de 3 patillas, V5+, GND, OUT, con la tipica resistencia de 220 omhios, etc... y funciona perfectamente con un mando universal, habiendole encontrado el codigo perfecto de emulacion.

Ahora.. el problema!

En el 90% utilizo placas con Pic's como el 16F877A utilizando el PicBasic Pro 2.50a y como Frontend el MicroCode Studio y me encuentro con el problema de ya para empezar algunos mandatos como el "LOOP UNTIL" no me lo reconoce, entiendo que hace repetir el loop en caso de cumplirse la condicion que tiene por delante, pero.. lo he adaptado a PicBasic Estandar y no me funciona.

Este seria el codigo adaptado ( segun entiendo y he podido... ) al PicBasic Pro ( y que no me funciona ):

C�digo: [Ocultar]

 
define osc 4
 
Include "modedefs.bas"
 
irsensor var portc.6
 
irPulse VAR Word
 
remoteCode VAR Byte
 
bucle var word                                   
 
inicio:
 
remoteCode = 0
 
inicio2:
 
RCTIME irsensor, 1, irPulse
 
if irPulse > 1000 then goto inicio2
 
PULSIN irsensor, 0, irPulse ' Get data pulses.
 
IF irPulse > 500 THEN remoteCode.BIT0 = 1
 
RCTIME irsensor, 0, irPulse
 
IF irPulse > 300 THEN remoteCode.BIT1 = 1
 
RCTIME irsensor, 0, irPulse
 
IF irPulse > 300 THEN remoteCode.BIT2 = 1
 
RCTIME irsensor, 0, irPulse
 
IF irPulse > 300 THEN remoteCode.BIT3 = 1
 
RCTIME irsensor, 0, irPulse
 
IF irPulse > 300 THEN remoteCode.BIT4 = 1
 
RCTIME irsensor, 0, irPulse
 
IF irPulse > 300 THEN remoteCode.BIT5 = 1
 
RCTIME irsensor, 0, irPulse
 
IF irPulse > 300 THEN remoteCode.BIT6 = 1
 
' Map digit keys to actual values.
 
IF (remoteCode < 10) THEN remoteCode = remoteCode + 1
 
IF (remoteCode = 10) THEN remoteCode = 0
 
Lcdout $FE, 1   ' Borra pantalla LCD
 
Lcdout "IR Valor= ",dec5 remoteCode ' Muestra valor del codigo pulsado
 
IF remoteCode=110 THEN high portb.4 ' Enciendo LED - Flecha Arriba
 
IF remoteCode=111 THEN high portb.5 ' Enciendo LED - Flecha Abajo
 
IF remoteCode=116 THEN high portc.4 ' Enciendo LED - Flecha Derecha
 
IF remoteCode=117 THEN high portc.5 ' Enciendo LED - Flecha Izquierda
 
goto inicio:

Alguna idea ???

"Los robots ser�n m�s inteligentes que los humanos en 2050",dice un director de Intel

* A esta m�quina la han bautizado como 'The Singularity'.

* Tambi�n se investiga una especie de plastilina, inteligente y animada.

* Ha sido en un congreso para presentar los avances en este campo.

Justin Rattner, director tecnol�gico de Intel, ha declarado en el marco de un Foro de Desarrollo Tecnol�gico, que para el a�o 2050 las m�quinas ser�n m�s inteligentes que el ser humano. La idea del encuentro era presentar los avances que en este campo de la ciencia se est�n llevado a cabo, informa BBC.

"No hay duda de que una de las cosas que ocurrir�n en los pr�ximos 40 a�os es que lograremos acortar la distancia entre las m�quinas y la inteligencia humana", dijo a la BBC Justin Rattner. Los expertos incluso ya tienen un nombre para esta m�quina m�s inteligente que el humano. La han llamado The Singularity (La singularidad).

"Lograremos acortar la distancia entre las m�quinas y la inteligencia humana"

Seg�n Rattner, la compa��a est� investigando en el campo de las relaciones entre los social, lo rob�tico, a la vez que en el campo de las se�ales inal�mbricas que ayudar�n en un futuro a una computadora a "sentir" el mundo que la rodea.

"La capacidad del ser humano para comunicarse con las m�quinas y de �stas para comunicarse con el ser humano ser� mucho m�s eficiente", agreg�. Rattner afirma que "quiz�s nos estamos acercando a un punto de inflexi�n donde el ritmo de los avances tecnol�gicos se est� acelerando a una tasa exponencial".

Microrobots

Un grupo de cient�ficos tambi�n presentaron, durante el mismo seminario, otra investigaci�n sorprendente. Una tecnolog�a que utiliza miles de millones de robots microsc�picos capaces de tomar la forma de distintos materiales.

Es una especie de plastilina, pero inteligente y animada, que cambiar�a de forma seg�n las necesidades.
