can nyone help me with interfacing pic16f877a and adc0809(lm35 is d input to adc).......the internal adc is nt accesible.....i hav tried out sm programs but in vain........if nyone can help me by giving d code it wl be helpful....its urgent!!(date of submission crossed)...
 

we are working on a kit and the porta(which has the adc) is used for sm other inbuilt led glowing purpose in the kit itself and the male connector in the kit does nt have the pins for porta.....
 

the link u hav given is not opening..!!.......we have tested with porta by giving an analog input to it.....the voltage at the porta pins is reading 1.75v and wen we are giving an input(lm35) to porta its o/p voltage is showing 1.55v and we are getting the corresponding value in adresh after a/d conversion.....y is it happening lik dis.....can we connect to the pins of PIC directly by separate wires in a kit?? ....
