    Proteus x Mplab Source Code

    Hi guys. What is the difference between these two procedures for the reset and interrupt vector. One in mplab and one in the Proteus? org 0x00 ;reset vector goto Start org 0x04 ;interruption vector goto Start PGM code 0x0 Goto Start ORG 4 ;some code here PGM code Start

    Dimmer Circuit Simulation Problem

    Hi I am trying to make a dimmer circuit with proteus. But it is not working according to our calculations. I am very new both in proteus and also learning about OP-AMPs. So I am not understanding what's wrong with the schematics. Both the current and voltage is showing zero. Here is the...

    Power factor correction circuit with PIC16F887

    I have made a circuit in Proteus with the PIC16F887 for measuring the voltage, current , power and also power factor and display them on the LCD. In the circuit, the L1 and R5 can be any value as it is just a value for the load connected to the circuit. I was wondering if I were to place some...

    Simulation not working well in Proteus?

    I'm not understanding Proteus or something I'm doing wrong, and it's really basic, I put a 9v Battery, a Red Led, simple circuit and a 10k resistance, so the led shouldn't turn on right? Well, is turning on even If I set a 1000k resistance...what I'm doing wrong? I've done things in Livewire...

    0 to 9, 9 to 0 counter

    Hi there, got a serious problem about Counters. i have to create "a circuit that counts from 0 to 9 then from 9 to 0 using two separate counters" and "must consider BUS concept". i used two 74192 and two 74153 Multiplexers ( for BUS ), one of the counters is ascending and another one is...

    Simulate PSoC in Proteus

    Hello. I am working on extracting strain gauge values mounted on my ATV (front suspension) with the help of a 20 bit ADC of PSoC. Before that I would like to simulate it. So could you please suggest how can I do this in proteus(or any other SW if not possible). Please help. Thank you for your time.

    Assembly Language Program

    So we've been instructed to write an assembly language program to display numbers 0-9 on a common anode 7 Segment Display and simulate it using the Proteus Software. (8051 microcontroller) (And 0-F as well) I'm a complete beginner in this field and was hoping that I'd get some help here from...

    PIC16F877A DS18B20 multiple sensors connection

    Hello. I have a problem with connecting N number of DS18B20 sensors on pic16f877 microcontroller on same pin in proteus simulation. I got it working with one sensor. But I cant get it working with multiple sensors (number of sensors greater then 1). So the C code needs to do next: when I connect...

    Hello cool people, I'm new to Proteus and overall designing digital electronic circuits. I have to design a 4 BIT ALU unit capable of adding, subtracting, multiplying using full and half adders, so the information has to enter by 2 registers of 4 bits type D, and have a selector system that will...

    The ohmmeter shows wrong output resistance of an optocoupler in Proteus

    In the attached Proteus circuit I used optocouplers NSL-32SR3. Its dependence on the LED current is depicted in the attached graph. Unfortunately for some reason the ohhmeters show always 100MOhms, and it doesn't matter on the applied to LED current.

    Is it valid to create your own model of optocoupler in Proteus?

    I'm modelling an all-pass filter which uses optocouplers with linear output resistance characteristics. The scheme is in the attached file. I was suggested to use any of these optocouplers...

    Problem with simulation in proteus???

    I built the circuit for simulating the all-pass filter by using optocouplers. But I don't know why its frequency response differs so much from the same but with the resistors instead of the optocouplers.

    using from 74185 IC (binary to BCD converter) in Proteus

    Hi, I try to design circuit that convert 10 bit binary to BCD with 74185 IC in Proteus, but when i run this project output of this IC like this attached picture is unknown(IC don't work!) and I did active enable. why? and how can give suitable output?
