Re: how to minimiz of horominc problem in electric DC drive
thank u sir, actually the assignment required to explain the different operation of electric motor in electric light rapid transit system (LRT) . the different operation must include the starting accelerating , steady state, change of...
HI everyone
Need some suggestion here
There is a school project that I need to develop electric drive system , they are asking about the minimization of harmonic problem.
I want to know basically what are the factors for minimization of harmonic in electric drive system (DC drive).
Thanks
Hi I meausred the resistance but it shows 0 ohm, but while I measure the voltage and I apply force with my finger it shows various number, anyhow do you know how much should be the power supply (excitation voltage) assume that I want use half bridge circuit (two strain) or full bridge circuit...
I have bought strain gauge but I do not know how is the connection ? I mean which one is output or.... here is the photo of strain gauge, I searched alot but I didn't get it .
this link gives me the information but still confusing how much must be the value of resistors in the circuit ? is it...
Hi actually this algorithm I can't got the logic , can you give me the sampe ?
I am using dip switch and i want to display it in LCD and count it down until zero.
I just write the code as :
dip_read = PORTB ;
now I think I need to convert the dip_read value to decimal
right ?
do you have any idea ?
not actually i need to set the time so I prefered the normal one as the binary value set the time in seven segment , my problem is how to program to read the value from DIP switch and the display it on seven segment,
thanks
Hi Im back I had exam until today, I want to start the assignment today, actually Ive got news that for this assignment we need to use DIP switch to set the time, I know how DIP switch works. is anyone have sample code for DIP switch ?
after the time set and displayed in seven segment then it...
thanks a lot sir
The following are the design considerations to be followed:
1. Set the time using a DIP switch (maximum value is 99 seconds)
2. The setting values should be displayed on the seven segment display
3. The spin process should begin when the start button is pressed and then
„h...
Hi guys I have same problem I need to show counter on seven segment which count from 99 to 0, using PIC microcontroller and assembly language ,
any idea ? thanks
thanks for your advice , so is better to write with assembly language from the first, yes I have chosen PIC16F877A because I have it already ,
do you know how to write the program for counter ?
thanks
the lecture asks to write the program wish assembly language , I think I can write it with C and then convert it to assembly language , I heard that there is software which is able to convert C to assembly language , right ?
