Podrias construir un medidor de frecuenciaLos de MADLAB tienen este, podriamos basarnos. Simple low-cost digital frequency meter by MadLab En el cual estos posts nos vendria de mucha ayuda durante el processo: Programacion del PIC16F84 (ASM)http://foro.elhacker.net/index.php/topic,36031.0.htmlMini-intro al PIC16F84...http://foro.elhacker.net/index.php/topic,27770.0.htmlaunke este proyecto esta hecho con otro PIC el tutorial del PIC16F84 de BADBYTE sirve de base para el aprendizaje del uso de los PIC Y para poder basarnos en como hacer el Frequency Meter ocuparemos esta WEb. Esta en ingles claro pero yo lo tradusco o lo hacemos todos con bavelfish http://www.madlab.org/source/frqmeter.txthttp://www.madlab.org/kits/frqmeter.htmllist F=INHX16,P=16C54
;************************************************************************** ; FILE: frqmeter.asm * ; CONTENTS: Simple low-cost digital frequency meter using a PIC 16C54 * ; COPYRIGHT: MadLab Ltd. 1996 * ; AUTHOR: James Hutchby * ;**************************************************************************
;************************************************************************** ; * ; Summary * ; * ;**************************************************************************
; The following software functions as a frequency meter with an input signal ; range of 15Hz to ~ 8MHz and with an accuracy of +/- 1Hz.
; Signal pulses are counted over a fixed time interval of 1/8 second or ; 1 second. High frequency pulses are counted over 1/8 s to make the meter ; more responsive with no loss of displayed accuracy.
; Pulses are counted using the real time clock/counter (RTCC) of the PIC, ; which is set to increment on rising edges on the RTCC pin. The 8-bit ; hardware register is extended by software into a 24-bit pulse counter. ; If the RTCC rolls over (msb 1 -> 0) between successive polls then the ; high two bytes of the pulse counter are incremented.
; The RTCC is unable to count more than one pulse per instruction cycle ; (per 4 clock cycles) so the prescaler is used at frequencies above ; 5MHz (20MHz clock / 4) and also to ensure that pulses are not lost ; between polls of RTCC (which would happen if more than 128 pulses were ; received).
; Timing is based on a software loop of known execution period which is ; iterated using a 16-bit loop counter. The loop duration is 20 us which ; gives integer iteration counts to time 1 s (50 000) and 1/8 s (6 250).
; The frequency in binary is converted to decimal using a powers-of-ten ; lookup table. The binary powers of ten are repeatedly subtracted from ; the frequency to determine the individual decimal digits. The decimal ; digits are stored at the 7 bytes at 'digits'. Leading zeroes are then ; suppressed and the four significant digits are converted to LED data ; for the 7-segment displays using individual lookup tables.
; The signal frequency is displayed on four 7-segment displays. The displays ; are multiplexed which means that only one display is enabled at any one ; time. The variable 'disp_index' contains the index of the currently ; enabled display. Each display is enabled in turn at a sufficient frequency ; that no flicker is discernable. A 5-bit prescaler ('disp_timer') is used ; to set the multiplexing frequency to around 1KHz.
; The display always shows the signal frequency in KHz, according to the ; following table:
; ----------------------- ; | Frequency | Display | ; ----------------------- ; | < 1Hz | 0 | ; | 1Hz | 0.001 | ; | 10Hz | 0.010 | ; | 100Hz | 0.100 | ; | 1.000KHz | 1.000 | ; | 10.00KHz | 10.00 | ; | 100.0KHz | 100.0 | ; | 1.000MHz | 1000. | ; | > 8MHz | E | ; -----------------------
; Underflows (frequencies less than 1Hz) or no signal at all are displayed ; as a single zero, and overflows (frequencies greater than 8MHz) are ; displayed as the letter 'E' (for error).
; Use is made of the indirection register of the PIC (FSR). This is set to ; point to a register in the register file which is then accessed using the ; dummy register address of 0.
; A pecularity of the PIC's instruction set should be noted. The subtraction ; instruction (subwf) does not behave as one would expect. Specifically the ; carry flag is complemented. In other words a subtraction that underflows ; clears the carry flag rather than sets it. This should be borne in mind ; when studying the multi-byte arithmetic macros that involve subtraction.
; This file is written to assemble using MPASM from Arizona Microchip. ; Decimal constants are preceded by a '.', hex constants are followed by ; an 'h'.

Joder, segun lo que sabia yo no era XBOX 360 era XBOX 2 estas seguro? Mira esta noticia. Según el documento la Xbox 2 podría incluir tres micros PowerPC G5 a 3,5Ghz, una tarjeta gráfica ATI con procesadpr a 500 Mhz y 256 Mb de RAM compartidos para la tarjeta gráfica y la CPU. Los tres micros irán montados en un mismo chip, soportando dos instrucciones por ciclo de reloj para cada uno, lo que proporcionará un total de seis hilos de ejecución disponibles para los juegos. Cada procesador incorpora una caché L1 (de primer nivel) de 32 KB para instrucciones y otros 32 para datos y los tres comparten una caché L2 (de segundo nivel) de 1 MB. En cuanto a la tarjeta gráfica, el procesador para shaders tiene 48 Unidades Lógico-Aritméticas (ALUs) que pueden ejecutar 64 hilos simultáneos en grupos de 64 vértices o píxeles. Las ALUs pueden ejecutar una operación vectorial y otra escalar por ciclo de reloj, para un total de 96 operaciones con shaders por ciclo. La GPU lleva una memoria embebida de 10 MB, muy rápida y que funciona como una especie de caché intermedio entre la GPU y la RAM unificada. El chip de ATI incorporará un superconjunto de funciones de DirectX 9.0 (incluyendo soporte para HLSL - High Level Shading Language - con soporte para shader model 3.0 y añadidos a éste). La consola incorporará puerto de red a 100 Mb y puertos USB2, aunque es más que probable que no incluya disco duro de serie, que podría ser adquirido como extra. En cuanto al sistema operativo que emplearía, sería similar al de XBoX, y basado en Windows NT. Microsoft no ha confirmado oficialmente ninguna de las características anteriormente mencionadas Hasta Pronto

Hola, abro este hilo para que todos compartamos que camara tenemos, porque la tenemos, y que nos gusta sobre ella. Porque hago esto, pues talvez en el futuro alguno de nosotros se quiera comprar una camara y si compartimos en este post, daremos buenas sugerencias sobre las nuestras. El formato preferible que le daremos es este... Equipo: Foto: Caracteristicas: Sugerencias: Equipo:Yo tengo una Nikon coolpix3200 Foto: La mismita de la foto igualita... Caracteristicas:Aqui les dejo algunas caracteristicas de la camara... 3.2 Megapixxeles efectivos. 3x zoom optico 15 scene modes memoria integrada. Cuando la compras trae todo, memoria extra y cables y drivers para la PC. Sugerencias:Pues a mi Padre le costo como 300$ dollares, tiene una resolucion exellente, y tira una imagen perfecta esta camara me gusta muchisimo y estoy muy contento con ella, no me a dado ningun tipo de problema. Hasta Pronto

Para los Mod-Chips revisa en este link: http://www.mod-chip.com/El Mod-Chip cuesta alrededor de 80$ si lo das a que alguien te lo instale, pero si lo instalas tu mejor. Yo instale el mio, solo ocupe el Mod-CHip claro me costo 40$ y un soldador de estaño y el maual de como ponerlo... El modchip o chip pirata a salido ya en varias versiones... Despues para el Xboxlive, necesitas comprarlo, este cuesta como 80$ y necesitas comprar una tarjeta de membrecia para poder jugar, una de un año te cuesta 12 o 20$. Hasta Pronto
