    simulator like isis for altera cyclone II

    simulator like proteus for altera cyclone II Hi , I am new to fpga. and just started off with a simple square wave generator. To simulate this I used QSIM. The simulation was pretty decent and got outputs with the VHDL code( IDE was QUARTUS II,v12).... But the problem is for...

    How to simulate VHDL testbench in Modelsim?

    @k-j but for simulation shouldn't we compile the code and check for errors?? thanks for the help:)

    HELP!! PID with PIC16f877a

    I am trying to build a line follower using PID code..How can I vary the speed in accordance with the error from formula??? it's like when: error | Motor1 |Motor2 0 | max | max -half| 0 | half_max - full...

    line follower simulation

    Is there any software to simulate a robot take, a line follower in action.. I mean we can adjust the bot's sensor's and specifications and the surrounding environment , then the robot moves as per the code burnt in the microcontroller??? coz checking hardware conditions are lengthy and we can...

    pic16f877a THREE SERVOMOTORS SIMULTANEOUSLY!!!

    @BradtheRad: 3 pins of the uC sends pulses to the 3servo's separately...anyway using timers i figured it how!! @bigdogguru: ur link ws helpful!! I will try to post the code soon ---------- Post added at 23:07 ---------- Previous post was at 21:38 ---------- I tried using timers to control the...

    pic16f877a THREE SERVOMOTORS SIMULTANEOUSLY!!!

    @BradtheRad: Thnx for the reply... I am using these 3 motors at separate pivots...just like a mechanical model of our hand..for picking objects!! bt the problem lies in one uC giving 3 different waveforms at same time to the 3 servos @bigdogguru:: thnx

    pic16f877a THREE SERVOMOTORS SIMULTANEOUSLY!!!

    I am trying to build a vehicle with an arm attached to it...as a part of project.. The project demands the use of 3 "servo" motors so as to keep the torque always... The problem is the microcontroller pic16f877a needs to deliver signals of ON time(1-2ms) and time period 20ms... simultaneously to...
