how to send adc reading to 16x2 lcd and simultaneuosly serial port............
If anybody have this programme then Give me full programme of lm35-adc0808 yar.
send me on my id firstname.lastname@example.org.
did u got full programme of lm35-adc0808 ????????
we are facing problems in adc0808 ...our vcc is 5v ..what will be our vref?....
Hey man i m trying to interface pressure sensor with adc0808. namely honeywell sscdann030paaa5 it has a range of 0-30 psi with min v0 = 0.5v and max 4.5v with resolution of 12 bits(analog) means i think it has a stepsize of (4.5-0.5)/2^12 = 0.97mV.
m i doing correctly?
and secondly if m doing correctly then what voltages i put on both vref pins.
i m currently giving 0.5 at vref(-) and 4.5 at vref(+)
will it show me correct value on lcd interfaced with at89c51?
i m little confused here i hope u'll reply as soon as possible. and thanks for your lm35 tutorial now i dont need to multiply adc value with constant to get correct value :-)
just as like as lm35 i want to do it for pressure sensor too...... m confused alot :-(
how to read battery voltage(9v) using ADC and 8051?
hey anybody can tell me how much delay time in above assembly programme
sir what about clock signal pin
