I wrote an assemply program to generate pulses like this 00110011 and move on the Port, I Connected Four pins to the Damn ULN other Four of ULN to stepper Motor.... I conected 9 pin of ULN to -ve and 10 to +12V which is volt of stepper Motor... The Problem is ULN is Not Working.. The Program is working Fine, i checked with LED's directly from 8051 and working checked from the ULN and Nothing so what is the Problem ?????
hi,
Is the -v [0V] of the ULN connected to the 0V, of the 8051 supply.??
No, Separated
They MUST be connected together else the 8051 cannot drive the ULN
ok i will try, if this ruined my at89c51, you will pay me $1, price of the chip here in Egypt and Thx for Help
Is Egypt a 3rd world country?
In Canada where many people are paid $100 an hour at work, $1 buys almost nothing. A newspaper costs $1.25 or more. A loaf of bread is $1.50 or more. A liter of gasoline is $1.28 today.
Egypt was a world leader a few thousand years ago. What happened to change things? Was it your religion that messes everything up?
