if i change the instruction little bit how would it change the order of the instructions ?? :
for (line=0,cl=0,temp=0;temp<=i,cl>15;cl++,++temp)
{
proc1();
proc2();
}
thanx for the fast reply,

i want to scroll message by 2x16 lcd cell by cell and line by line and i m wondering weather i can do it automatically by the lcd features and instructions or i should do it by software ????
thanx in advnace,

hi,
let me put some light on the physical side:diode is a non linear device because the current that flows through it is proportional to exponent.rd is the differential resistance of the diode and is determined by the potential difference on the diode. when ac is small dc potential is much...
Re: I have a problem with pic16f84a plz help??????????!!!!!!
your controller is in reset state which all the ports are in 0 state.i dont see that u used the TRISB register. configure portb as output by using the instructions:
clr TRISB
by the way u wont see the change unless u r using scope.i...
thanx for the reply you both....
ian thanx for the backup . i build the ciruit and its working fine.
the battery diode wo'nt let current from the transformer to flow and the transformer diode w'ont let current from the battery to disturb its work and they can both work together though its not...
hi,
i want to build a 5v regulated source based on 7805. i have 9v battery and 9v wall transformer 200ma. i would like to combine them together because i may use them both ( i want to mobile the unit ). can i only connect diode at the output of each source to prevent interference from the other...
hi,
i am talking aboat one interrupt source !!
what the program will do if an interrupt of the same source is asking to branch.
will the program go immediatly to the start of the interrupt or avoid the interrupt completly and finish the first interrupt.

hi,
i m programming Pic 16f877 with c and wondering what happens when an interrupt is happenning when the program is proccessing an interrupt call.

interfacing keyboard microcontroller
hi,
if u send the electric diagram it will be much more easy to help u.
r u using bi-directional communication or uni ?? make sure that the microcontroller's control pins are configured as input when using uni direction (in my opinion keyboard-host is...
the formula to calculate the capacitors is:
cl=(c1*c2)/(c1+c2)+cs
cl is load capacitor whice is mentioned in the data sheet
cs is the stray capacitor of the printed board typically 5pF
c1 and c2 is the parallel capacitors. usually its the same value
