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.

A special thanks to Sunil Raina, Piyush Sonawane and Parimal Sikchi for sharing their work with us.

help please how do i initiate port 3 as an input port in assembly? acutely there is push switch connecting to p3.2 push switch connecting to p3. 3 push switch connecting to p3.4 push switch connecting to p3.5 and i need to call function when the user pressed the push switch for the previous pins (not used as counter and not as timer… just call a function ( do special thing) when any push switch is pressed ???????

Hello, I am referencing this project: http://www.8051projects.net/wiki/I2C_Implementation_on_PICI am using PIC16F1847 and XC8 so I've had to make a few changes to the code. While making changes, my compiler gave me an error for the I2CWait function for the while statement. It says "unexpected token amp". Here is the line in question:while ((SSPCON2 & 0x1F ) || ( SSPSTAT & 0x04 ) );I changed the register names to be consistent with my PIC but it didn't solve the problem.What changes do I need to make to this function so that this error does not occur?
