When I am using Timer1(or any other timer),what exactly means value in 16bit PR1 register?
Is it number of cycles,or maybe time in microsec?
Thanks

if this is still active,let me know,I have some simple and not very expensive solution

for inputs using cheap diodes(7 inputs and only 3 pins)
and for outputs using NOT and AND gates(3 pins for 7 outputs)

so theoreticaly you can have n pins and 2^(n-1) inputs or outputs!

just out of curiosity,how would IR sensor know if a person entered or left the room?

well maybe it is an old message,but I have one really simple solution:

If you do not need 6 separate limit switches (and separate inputs) ,you could just wire them all in parallel (if they are NO) or serial (if they are NC) and have only one input capture!

hey,man it works!
thanks ,I gues if I go out of the loop in one line,can`t go back at the beginning,so this code really works!
BTW,I`m kind`a new to this,just learning micro c as well as c++

Thanks again

Now I`m working with half step

[quote="miskol"]i've been trying to just turn on an LED using dsPIC30F4013 for 3 days, everything seems wrong to me and i dont even know where to learn from to start from beginning. Below is the programming that i think should really turn ON the LED and makes it blink for each sec. my first question...

Can anyone tell me what`s wrong with this code? void main() { char x,y,z,a,b,c; x=1; y=5; z=9; a=0; b=0; c=0; ADPCFG = 0xFFFF; TRISB=0XFFFF; TRISD=0X0000; ret: while (1) { if(PORTB.F0==1) if (a==0) goto mota; if(PORTB.F0==0) a=0; if(PORTB.F2==1) if (b==0) goto motb; if(PORTB.F2==0) b=0; if(PORTB.F4=...
