Input and output
hm... my problem is i cannot store ics test pattern because the PIC cannot be made input or output many time. input for IC 7400 and input for IC 7402 are not same. Output also not same.. how can i test this ic using PIC..
hello.. i want to design IC tester and i'm using PIC16F877A to test my ICs. every IC has its own input and output and not same for each ICs. i want to test ic from 7400 family.
Can i set Input and output severally for my PIC16F877A according to ICs input output?
motorola and pic
actually i want to design ic tester using PIC16f877 and interfece with 4x4 keypad, lcd and PIA6821 as interface with ic under test on ZIF socket. but the problem when interface with PIA and PIC.
16f877 programming
hi... can u help me? i want to design an ic tester using PIC16F877. but i have a problem to connect PIC and test zif socket. can u give me a schematic of ic tester using PIC16F877?
hi..
i want to design ic tester using PIC without PC . i'm using test zif socket to test ic 74xx but i have problem to connect it to microcontroller.
the microcontroller need interface to match each pins at zif socket. can anyone help me what is the interface from microcontroller to zif socket.
Is the pic16f877 need a componet as interface to connect to zif socket?
zif socket is used to test ic.
a componets used as interface to compare test patern.
IC Tester
The integrated circuit tester described here was designed to be connected to the parallel port of any IBM or compatible PC using a standard printer cable. The unit can be powered from the mains using a suitable AC adapter or alternately battery powered for portable use.
The tester is...
