please tell me,is this correct formate for pwm wave generation

HI, i am driving dc motor through mosfet with pwm, motor will rotate 1sec forward and 1 sec reverse with various speed. my code giving pwm single time only then maintaining zero

#include "I&# ...

dear all i changed crystal value (16mhz) . i got perfect output thank you very much sir................ Very Happy

sir i checked normally it has 0.8 v
when connected variable resistor for adc input

adc v --------------- controller pin (v)

starting ---- ...

thank you dear Ttelmah i got continuously 5.0 volts, i used your code, again thank you for your valuable code, i used 20mhz crystal 22pf capacitor in my hardware circuit.

even i am connecting adc to gnd result is 255 sir didn't show 0

8 bit adc enough this application sir , i used int but simulation showed negative values ,if i use unsigned int and %u simulation showed 0 to 255
properly ,i checked in a0 pin during the adc input ...

dear all, i am using pic18f4431 controller. I am using adc channel pin a0. I got 255 only in serial window through hardware crystal value 20mhz. Pls help me dear all
