Abstract
La presente invención tiene por objeto dotar al ordenador personal de un sistema sencillo capaz de realizar las funciones de un osciloscopio y un generador de señales. La sencillez radica, principalmente, en que el circuito se acopla directamente al puerto paralelo del ordenador. El invento consta de dos conversores. El conversor analógico/digital es el encargado de leer una señal alterna de entrada (ver gráfico) y enviar la señal convertida en digital al ordenador. Esta señal, que tiene 8 bit, se envía en dos fases 4 bits-4 bits al puerto paralelo. Un software apropiado convertirá estos datos en un valor (entre 0 y 255) y dibujará la señal. El conversar digital/analógico realiza la función inversa. Lee los 8 bits que le llegan del puerto paralelo y los convierte a tensión alterna. El programa de ordenador genera, en función de la señal que se quiera enviar, bytes entre 0 y 255 que se convertirán a tensión entre -1 V y 1 V.The present invention aims to provide the personal computer with a simple system capable of performing the functions of an oscilloscope and a signal generator. The simplicity is mainly that the circuit is coupled directly to the parallel port of the computer. The invention consists of two converters. The analog / digital converter is in charge of reading an alternate input signal (see graph) and sending the converted digital signal to the computer. This 8-bit signal is sent in two phases 4-bit-4-bit to the parallel port. Appropriate software will convert this data to a value (between 0 and 255) and draw the signal. Digital / Analog Talk performs the reverse function. It reads the 8 bits coming from the parallel port and converts them to AC voltage. The computer program generates, depending on the signal to be sent, bytes between 0 and 255 that will be converted to a voltage between -1 V and 1 V.
