Re: Use of Data pins of LPT
Sorry here is the pin layout:
1 -strobe
2-9 D0-7
10 -Ack
11 Busy
12 PE
13 Select
14 -Auto Feed XT
15 -Error
16 -Init
17 -Select in
18-25 GND (mostly shielding)

Re: Use of Data pins of LPT
Just like on a PIC or so. Use the address 278 LPT2 or 378 LPT1 to access the ports.
Depending on the program that you use.
But the law stays the same. Access the address then read from or write to the
address. Always watch the size of the data you send.
Just make...
Re: how can i start
Another could place that shares C is microchip.
It is the same as on a PC just using a bigger "PIC / Microcontroller".
It is a lot of fun using C than ASM. But you need to learn ASM
in order to under stand the devices regesters, stacts, est...
Enjoy and good luck.

Re: what is difference between MALLOC & NEW, FREE &
Malloc => Use a current variable and asign a diffrent size memory allocation for it.
New => Create a completely new memory allocation for that varible.
Delete => Delete the current memory allocation and variable index. (This destroys the...
Re: Designing led with PWM
That is right. The faster the switching the more brighter the LED become.
The slower the less brighter it becomes. But if to slow then youre LED will show a flash.
For access turn the port line on and off. |_|-----|_| long |_|-|_| short.
The short should be the...
Re: 2 rotated images
Did you load them on the Canvas or into a image box.
If on the Canvas you can write a little roteen that can rotate the image.
Else do the image in Paint shop or so and reload.
Do you want to rotate the image in run time?? :sm35:
Re: RC Notch Filter Doubt
Agreed.
If youre simulatar has the option make sure you fed it the
real values in for each component. On some of my
simulators I got diffrend results.
That is why I prefer to see before passing a cicuit on.
Re: gps in a robot?
I don't know your exact application.
But if you are in a set area you can use
a RF, sonar or so system to tell the robot in which part of the
grid he is in.
GPS has a lot of IC that requires it to work. So it can become costly.
I will look and see if I cant find a cheap...
Re: Big Problem!!
Sorry had to wait for the picture to come trhugh.
Try a parrallel resistor of equel size.
That should devide the voltage in half. But if the
bath has resistance you will need to lower it.
epp already stateted that.
Lets say the bath has a 10E resistance than place a
90E at...
Re: Big Problem!!
I think you forgot to add a comment to the file. Can't see it.
I agree with epp. You need a resistor to limit your current.
Do you know how much current you circuit requires?
If you to you can work out the total resistance to get the value
for the limit resistor.
But...
Re: Ground plane
akouz
Thank you for the reply. Do you know where I could find out
more about the groud pour rules then. Or can I just connect
the pour to the GND track.
