you have to send ascii value of each number one by one then and then it will display the whole number.
for seperation of digit from whole number say 247 then do division by 10 and module by 10 to get separate each digit then send their ascii value to lcd.
hope this will help you
first igbt is got heated at 20khz frequency, my duty cycle variation is = 10% to 98% at all above switching frequency.
the output frequncy of my inverter is 50hz that i saw on power analyze. the variation on o/p frequency is less then 1%.
my problem is as i increse switching frequency my igbt...
hello friends,
i am working on three phase inverter. i use pic18f4331 microcontroller for pulsing irfp450 mosfet, i use ir2112 as mosfet gate driver,
my experimental result is as bellow..
Fpwm ----------- Vdc(i/p)-----------Vac(o/p)----------THD----------sinusoidal---------- no.of...
hello friends,
i am designing 3-phase inverter drives,and i have got satisfactorily result for without load. now when i rotate motor with some load my drive output current is incresing drasticaly and speed of motor also reduce to almost zero. i don't know why this happen?
please anyone can...
ok, i found that my supply frequency to motor is 50hz at 200vrms so i have to reduce it to 25hz for 200vrms, beacause 50hz is for 440vrms voltage,
and i feel that beacause of reduce speed upon appling load the reactance of motor reduce so that current is flowing more then expected.
am i...
hello friends,
i am trying to build variable frequency based ac drives, and i got success at 50-60%. in no load condition the drive works fine and motor runs normally and i can vary speed too. but now my problem is when i attached 1A resistive load motor speed reduced to half level from its...
hello friends...
i have install orcad 9.1 in my windows 7 computer.
but when i am trying to run capture then system error comes said that
" file enable32.dll is missing out from your system "
now what should i do??:roll:
hello friends,
i have probelm with avr studio 4 .
when i start it. it says "mfc application stopped working" and the program close.
please help me.
thanks in advance
hello friends,
i want to build laser distance meter with following requirement. if anyone worked on that please help me out.
1 it should measure upto 100m
2 it must works 3 days continuously.
3 with cm acuracy.
thank you in advance.

yes, my gps module support dgps facility.
what the meaning of "you would end up making your gps faulty at the end" ?
please specify what u mean to say.
