The digital IC tester is implemented by using the 89C51 microcontroller board. The processing of the inputs and outputs is done by the microcontroller. The display part on the microcontroller board is modeled using LCD. After the successful testing of the IC, the result is displayed on the LCD.
The basic function of the digital IC tester is to test a digital IC for correct logical functioning as described in the truth table and/or function table. It can test digital ICs having a maximum of 24 pins. Since it is programmable, any number of ICs can be tested within the constraint of the memory available. This model applies the necessary signals to the inputs of the IC, monitoring the outputs at each stage and comparing them with the outputs in the truth table. Any discrepancy in the functioning of the IC results in a fail indication, displays the faulty and good gates on the LCD. The testing procedure is accomplished with the help of keys present on the main board.
This project has been tested with most commonly used digital IC's, mainly belonging to the 74TTL series. Digital IC tester tests various types of IC's like OR, XOR, NAND, AND, NOT, NOR, XNOR GATES and also FULL ADDER, MULTIPLEXER, SHIFT REGISTER.

i am making a project of connecting 4 8051's using a can bus for which i am using mcp2515 and mcp2551.but before making it i want to ensure it works by simulating it on proteus though the two ic's mentioned above dont seem to have models in proteus so is there anyone who can help me with that

@sachinmm The 8051 timer can't do 1 second. It can do 50ms so count 20 times

How can one use XOR gate to ensure the first output is '1' and the next is '0'?

@baz..try adding a hash and a semi colon

@ExperimenterUK no..i dont do that i just type message example.. Hello my name is baz and then i click send message,

@baz..did you end your message with a hash and a semi colon

I want the program for v/f control technique of 3 phase induction motor
Sat Jun 13 2015, 07:06 AM
@ExperimenterUK okay thank you...but now I already complete and my dot matrix already light up but when i send message from pc to my hardware project it doesnt show any message on my dot matrix..its only blinking when i click send message....I really dont know whats the problem...I had follow all the steps...schematic and use the coding that have been provided..is it because firstly i had wrong burn the coding in AT24C16?? Is that effect ????
