OOPIC Forum

This Forum is Dedicated For all The Object Oriented PIC Lovers .......... The concept behind OOPic is straight forward. Use preprogrammed multitasking Objects from a library of highly optimized Objects to do all the work of interacting with the hardware. Then write small scripts in Basic, C, or Java syntax styles to control the Objects. During operation, the Objects run continuously and simultaneously in the background while the scripts run in the foreground telling the objects what to do.

no, it was giving around 8~9 volts
it was nothing about connections.

hi guys, ladies;

i have been working on a graduating project and i decided to use
oopic. few tries later, there was an error occured;
-------------
the fallowing was detected while establishing I2C communications

the I2C bus clock status reported a logic state 1, when a logic state
of 0 expected this could be caused any of the fallowing;

A. the programming port is not configured correctly
B. the programming cable was not attached to the PC (it was)
C. the programming cable's I2C clock line is not properly connected
D. the programming cable's I2C clock status line is not properly connected
E. the I2C clock line is shorted to +5 volts on the oopic or in the cable.
F. the I2C clock status line is shorted to +5 volts in the cable.
-------------------

i tried the cable, it was ok. i controlled it's connections. also
remade a new one still the same error.

i tried the troubleshooting page on the manuel. the oopic passed all
the tests also.

i tried the 10k on the resistance near to eeprom for capacitances.

i don't know what to do next. i need some advices.
thanks for your helps.

[oopic] LCD Displays

I have just about finished up a little project to use the oopic-c to
control a matrix of relays and switch the signals to an external dvm.
Ended up trying a few displays to see which I liked best. The one that
I chose from melabs.com works well. it has a buss for i2c as well as
serial but I didn't get around to trying that part. The code for the
oLCDSE worked just fine with their controller at 9600 baud. It is a
bit cheeper than the scott edwards device and they also sell just the
serial controller if you have a standard lcd display on hand. I made
up the pcb to connect to a standard display but that uses up a lot of
I/O. Posted a couple of pics in the photos page if anyone is
interrested to see the project.

[oopic] Re: The OOPic, Computer Vision and Remote Control

I have ordered the NTSC wireless camera for my first approximation.
There is a tutorial re: adding vision to a Lego NXT at the RoboRealm
site that discusses the camera, receiver and RGB->USB converter.
We'll see how it works out.

About 4 years ago I started to work on an R/C Hummer that I wanted to
have chase an orange soccer ball around the yard. I was never able to
get the CMUCam working well enough with local processing. I think the
wireless link for the camera and a BlueTooth link for the onboard CPU
(ATMega128?) should work out fine.

The parts should be here in a week or so.

On the high price end of things, the approach used by Surveyor is
terrific. There is a Blackfin on board (500 MHz) to handle the camera
interface and a Lantronix serial->Ethernet gadget to send the data
back to the host. RoboRealm can run on top of all this and control
the 'bot. But it's close to $500 for the 'bot and that's put it on
back burner until I learn a lot more about using computer vision.

I have to agree with you that RoboRealm is great free software. Since
starting to play with RR about a year ago my robot has evolved from
using on-board sensors to using a single fixed ceiling mounted webcam.
This has resulted in a robot that has progressed from stop-start jerky
type motion to one with smooth driving/steering and accurate navigation.
The robot is equipped with two juxtaposed colour disks (Red & Green) of
100 mm diameter, mounted parallel to the floor atop a short mast to give
an unobstructed view to the camera.
The RR program using a red and a green filter calculates the COG
co-ords of the two disks which is then read into a navigation
interface(VB6). To close the control loop, motion and steering data(SCP)
is streamed to the robots Oopic via a wireless RS232 link.

I would like to experiment next using an on-board camera but am yet to
find a suitable wireless network camera.

Hope you enjoy playing with RR as much an I have.

[oopic] The OOPic, Computer Vision and Remote Control

From time to time a user will post something about wanting to do an
OOPic project with computer vision. Equally often, some of us just
groan! Well, I do...

Things are changing. If you haven't played with RoboRealm, you may
have missed the best thing to happen to robotics in a long time.

Briefly, RoboRealm is about computer vision. It can take input from
wireless cameras (hence the application to OOPic and robotics) via a
translator (RGB -> USB), process the image (find the blue ball), move
the 'bot, grab the ball, find the orange cone, move to it and drop the
ball. See http://www.roborealm.com/tutorial/ball_picker/slide010.php

It also uses USB cameras or other sources like the network camera of
the Surveyor (www.surveyor.com).

The only piece missing is the link between RoboRealm and the OOPic.
This can be ANY serial link such as BlueTooth, Zigbee or any other
scheme. The communication protocol is simple: at each frame scan,
RoboRealm sends a sequence to the OOPic containing commands for the
next frame period while the OOPic sends back a sequence containing the
state of local sensors. See http://www.roborealm.com/help/Serial.php

I haven't had time to work on the interface because I am too busy
getting up to speed on USB and wireless cameras with the idea of
buying the Surveyor. OTOH, there is that tutorial for the Lego NXT
which I already have!

There are other input devices such as the keyboard or a joystick that
can be used to command the 'bot. There is a great tutorial about
interfacing with a USB Missle Launcher! In fact, it would be easy to
add tracking of a moving part of the image, get the CG (center of
gravity) and fire!

I have only been playing around with this for a few days but I really
think it is the most important vision software available.

Watch the movies for each tutorial to get an idea of the capabilities.

And, it's free!
