hi,
for a college project i require to generate a waveform of time period
T=50 microseconds continously from ports p1.1 and p1.2 using 89c51 ,
of which p1.1 should go high for 38us and go low
while p1.2 should go high after 2us remain high till p1.1 is high
and go low for remaining time period
i have written a program for the same and works fine on emulator and i have
burned it in the ic
but i dont seem to get an output when i implemented the circuit '
i think there is something wrong with the interfacing so can anyone provide me with circuit for the same
any help given is appreciated
