ok guys! the problem is solved by the Grace of Almighty Allah.

I removed the lcdout command, and now the coding works well:)

Thanks a lot for ur kind help

ok i will disable global interrupts and will check it. But interrupt is not a problem here. The first time it executes very perfectly, it is the second time that is creating a huge problem. Second...

actually my code is something like this



Include "Modedefs.Bas"

DEFINE HSER_RCSTA 90h
DEFINE HSER_TXSTA 24h
DEFINE HSER_BAUD 9600
DEFINE HSER_SPBRG 25

ok guys!

so i have studied a few threads here and made the following modifications in the SPI master program. but again the same problem is occuring. In the first iteration, the program runs very...

hi guys!

im using SPI between the two pics. here is my program for SPI master



'****************************************************************

hi guys!

im making a project that has two PIC18f452. one pic is acting as SPI master, the other is acting as SPI slave. The master makes portB.0 of SPI slave low which it takes as INT0 interrupt....

Hi guys!

i have setup a circuit that involves two PICs. both are PIC18f452. One pic (SPI SLAVE) has a sensor on its analog input, it senses the value and sends it through SPI to SPI Master PIC....

thanks for your help

mat jensson you have raised a nice point here. I have tried almost every possibility in my coding as well as in my connections, but its not working at all. Please explain me...

Dear jerson and mister e

i have rechecked my connections, they are correct. I dont know where is the problem. I have even grounded WP which i havent done before. One more technical aspect that i...

Dear fellows

Im facing problems working with 24C512 eeprom. Im posting here my coding. IN simulation, it seems to work fine on proteus but in the real it doesnt. Herez my coding.

Include...

Thank you for ur replies.

I want to tell you that im using Labview serial transmission. It is asynchoronous serial transmission. SO it can send 256 bits serially one after the other. On the other...

Hi guys!

Im using serial communications in labview. That is connected with PIC16F877A with serial interface. The labview will send a bit stream of data that will be greater than the WORD sized...

Hi guys,

im working on my project. that project is related with smart sensors. Im using labview to create a binary file which is of 256bit. Now i want such a system that can transfer this file...

haha Skimask!

that was superb Intelligence.

WEll! Im asking about the effect actually.

I want to know what is the effect of frequency over the running of a DC motor.

Does...

That was just superb!

I got it now how to deal with Software PWMs. Thanks a lot all of u!

Now can anybody tell me that how would i determine that what frequency do i need to supply in order to...

A bundle of thanks to u Mr. Skimask!

Now i have understood your coding. Thank u very very much!

As far as i have understood is this that let us suppose that the Left motor is having a speed...

Thanks a lot for all ur help!

@skimask:

Thanks for that idea ! Well! surely i have written up my own code as well, that dint work so i have asked on this forum to provide me some help. I do...

Hi guys!

Well! im a novice in robotics. IM making a robot which will be having two wheels in the differential drive formation. That is each wheel will be connected with one motor. So there will be...

Many Many Thanks Mr. Vladimir

please tell me the following two points as well!

1) Which type of LCD screen have u used. Can i use an LCD screen with three terminals (+5V, GND, control) using...

Hi guys!

Well ! i have some confusions in understanding the following program :

1) what is the purpose and function of this line :

DEBUG " Compass Bearing ", # bearing,13,10

2) Why is...

That was just tremendous Mister.

Im very very thankful to u for this.

Now im getting that this is really possible to control the cycles in HPWM.

Now i have some important questions...

Thanks for ur precious helo Mister.

but one reason that is just stopping me from using this sorts of PICs is this that i donot know how to program HPWM in the way in which i want.


Lets take...

very sorry for making a late reply. well here is the scenario in which i want to use this cascading.


I have made a robot in which there will be two drive wheels, each supported by a separate DC...

Hi guys!

well! i want to use PIC16877 for my two wheels that are driving my robot.

There is one DC motor attached with each of the two wheels so there are total Two DC motors for Two wheels. I...

Hi guys!

well! im using PIC16F84 in my robot system. What im doing is using two of them simultaneously. Now let me tell u that how i want to do this:

Supposing PIC # 1 is connected with my...
