#115144 - Why guessing? Responding to: ???'s previous message |
Why guessing? If you need to test a Nand-gate, then you have to apply to the inputs the whole truth table, and check the output accordingly: If you apply (0,0) to the input of Nand-gate, is the output (1)? If you apply (0,1), is the output (1)? If you apply (1,0), is the output (1) and if you apply (1,1), is the output (0)?
The same procedure for the other kinds of gates. Also, refering to your code: .
.
.
GOOD: SETB P0.1 ;Green On
SJMP EXIT
REDLED: SETB P0.0 ;Red On
EXIT: CLR P0.1 ;Green Off
CLR P0.0 ;Red Off
JMP MAIN
What do you think: How long will the green LED be on? Can you capture it with your eyes? Kai |
