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.

Re: [oopic] Strange serial operations

What type of ooPIC are you using? Can you post some code?

Re: [oopic] Serial settings question

If you are using a ooPIC R, ooPIC C or ooPIC S 2.2+ I don't recommend
that you mess with this. The ooPIC devices above are all 9600 baud, 8
bits, one stop bit, no parity.

Thanks Rich
That's just what I was lookin' for. I overlooked that zip file the
first time around. Another great item on that web site is the
breakout boards for the surface mount chips-to-dual in-line chips.
Finding a great looking chip and realizing it was only available in
surface mount was always dissapointing to me. Thanks again!

The factory provides a BUNCH of OOPic code at

http://www.micromegacorp.com/oopic.html

The simple example (that does nothing) is umfpu-serial.osc. It
provides the entire framework for an application without actually
doing anything. You insert your own code - perhaps something trivial
like add a couple of numbers and send the result to the serial port
as a string. There are many other LCD examples that will provide
guidance.

There is also a reference guide specific to the OOPic
http://www.micromegacorp.com/downloads/documentation/uMFPU-V3_1%
20OOPic.pdf The guide also provides tutorials.

Alas, I haven't bought the chip... I don't have an application for
it at this time.

[oopic] Strange serial operations

I'm using a TTL to RS232 converter to communicate with a load cell
scale Display. Sending commands to the Display works as expected but
receiving has some unexpected results. I can successfully communicate
with both OOPic and Display from my PC without any hardware control,
which is how I have the OOPic to Display setup. I am using the
oSerialPort object and my program copies the serial.value to
buffer.value as soon as the serial.received goes high. An example of
the value that is being sent to the OOPic from the Display is within
the quotes, " 0.355 kg" followed by a crlf. The leading
spaces/blanks and the numbers seem to consistently make it, but only 1
trailing space follows with a couple random characters, often either
ascii value 223 or 164. I can't see any reason why it should be a
buffer overrun. There is nothing else going on at the same time.
Anyone have any suggestions/experience with the OOPic's serial UART?

Hi Rich
Just took your advice and ordered one of the coprocessors. After
looking at the datasheet about interfacing with the OOPIC I'm still
confused about communicating with it (coprocessor). Can you give me a
sample code that would demonstrate how to do this?

[oopic] Serial settings question

Hi all,

I'm wondering what serial settings the oopic uses. It seems you can
change baud rate but what about number of data bits, stop bits,
parity? Can't seem to find anything in the manual/object list.

Thanks

Version A1 doesn't include the oStepper object. Nevertheless, look at
the documentation and you can see how to wire the driver and motor,
assuming a bipolar motor.

Then you need to define an oDIO4 and control the output pattern just
like oStepper - pick a pattern you like. The easy way might be to
define an array of step patterns. Use an index variable to step
through the array and send the patterns to the oDIO4.

Before you can wire the stepper, you need to know if it is unipolar or
bipolar. The documentation assumes bipolar. Google for 'jones on
steppers' for more information.

[oopic] Stepper motor with Oopic s

I would like to use oopic s A1 with Stepper motor and photocell. I am
not sure how do we do wire diagram and program it. Does anyone have
sample with code that I can take a look? I think stepping motor use 5
volts. I got it from Epson printer. It is SM-E040

[oopic] Re: URGENT - OOPic Events not functioning

Thanks for your help - I got the events working in time for the
presentation. Here's the general process I used (based on what others
said in this thread) in case anyone is still puzzled:

-Write code as if oEvent worked
-For each event, add these lines (or something functionally similar)
into your definitions section:

Dim RAM_Access# As oRAM
Const Event_Obj_Location# = 41 ' oEvent "Event" memory location
Const EventCode_Location_Hi# = 0 ' Event_Code EEPROM location High
Const EventCode_Location_Lo# = 67 ' Event_Code EEPROM location Low

(Where # is replaced by the event number)

-Event_Obj_Location can be found in the compiled code (with OOPic 6
compiler after making the code, this can be seen by going to
View->Compiled Code or the C tab, or Ctrl-F2). It's in the
Constructors.Begin section where the oEvent you're linking is defined
(e.g.:
C0039:008 ;Loc 52 Dim Event_Name As New oEvent
In the above code, 52 would be the relevant location).

-To find the Event Code location stuff, download and extract the Sub
Address Finder from the Files section in this group. Run this and load
the .OPS file that is generated in the code directory after you make
the code. It should give a list of subprocedure names and their memory
addresses. Look for the one corresponding to the event you're setting
up. It will give you one number. If this number is less than 256, then
EventCode_Location_Hi will be 0 and EventCode_Location_Lo will be the
number. If it's equal to 256, Event_Location_Hi will be 1 and
EventCode_Location_Lo will be 0. If it's 300, then Hi will be 1 and Lo
would be 44. As the guy who came up with this fix said, Hi is (the
EventCode address)/256 (dropping everything after the ones place) and
Lo is (the EventCode address)-Hi.

That doesn't really explain what's going on, but others in this thread
have explained that pretty well.

I am having problems getting other stuff working, but the problems are
kind of all over the place. I'll work on it a bit more tonight and may
post another question tomorrow if I'm still stumped.

[oopic] Re: Providing a clock/time to the PIC

Not sure if i have time to include additional components to my
project but i will look into it. Since its only a prototype, i could
include inside my future recommendations. Thanks Richard. So much to
microcontrollers than i ever expected. Glad that this yahoo grp is
here to help me.

I think for the inverse trigo, doesn't seem possible, maybe i will
just generate the values and make the oopic implement them. :)

Excellent, then I shan't bother with that route any longer. The pity of it is
that I may have discarded the working code I had for the non-VC route.

I wouldn't bother to make the compares in a VC - You are correct,
reading the I2C and then putting the data into variables takes enough
time that you won't see any particular speed improvement by trying to

[oopic] Oopic and CMUCAM 2

Hello all,

I'm trying to interface an oopic S with a cmucam 2 to make an object
following robot. I'm having difficulties, any help would be greatly
valued. Details follow:

I've got an LCD connected to the oopic and working fine. Camera TX
connected to oopic IO line 23, camera RX to oopic IO line 22. Also
have the camera connected to +5V and ground from the oopic (checked
with DMM).

Camera is on, serial jumper in place, jumper on pin 0 in place to
specify 9600 baud.

Code follows:

Delay = 1000

cmu As oSerialPort
LCD As oLCD(3,1,27,26,cvOn)
' Set camera settings
cmu.Init
cmu.Baud = 9600
cmu.Operate = 1

LCD.Init
LCD.Clear
LCD.Locate(1,2)

x:
cmu.Value = 65
If cmu.Received ==1
Then
LCD.VString = "Data received"
EndIf
Goto x

I get absolutely nothing on the LCD. Does the oopic use a stop bit in
serial transmission? Also, even if the baud/stop bit are wrong, there
should be SOMETHING in the received buffer, even if it is trash.

Thanks in advance
Ash

[oopic] Question about event design

I'm running into an issue where I might run out of object memory, so I have
to choose what to build as a virtual circuit, and what I should just leave
in code. I have two motors that run based on a countdown timer. I set the
value of the countdown object, and the motors run until the countdown
reaches 0. There are also 24 touch switches. My intention is that if one of
the switches is triggered, the countdown value is set to 0, thereby
switching off the motors immediately. I was figuring that this "reflex"
should be among the fastest things to happen, so I thought I might create a
VC for the switches. However, the switches are read from an I2C object, and
those can't be included in a VC directly. Therefore, I thought I would read
the three banks of switches into three bytes (I have to do this anyways,
because I need the bytes). Then the VC would use three oCompare0 objects to
check whether any of the bytes are above 0. An oGate3 object will OR the
three oCompare0.Above properties and trigger an oEvent based on whether the
oGate3 results in True or False.

However, the event triggered by the oEvent clears the counters, and sends
some information out the serial port. None of that is VC, but it has to
happen. It would be a bit more difficult to try to put the clearing of the
countdown timer into the VC, and I'm already pushing the limit of the object
memory, so I didn't seriously consider doing it.

My problem is that even this VC is gobbling up about 20 bytes, or about 25%
of the object memory, which appears to be acceptable, though only marginally
so. I don't have the event quite working yet (v B2.2+, so I don't have the C
oEvent bug), but I'm uncertain whether it's even worth doing. Considering
that reading the I2C into the three bytes is not part of the VC, and that
the event itself, where the countdown is cleared (in certain situations
only, so there are two if statements prior to the clearing of the value), is
not part of the VC, will I actually see much of a speed boost versus the
single line:

if alert1 > 0 or alert2 > 0 or alert3 > 0

which is all I am really replacing with the three oCompare objects and the
oEvent.

Try http://www.sparkfun.com/commerce/product_info.php?products_id=99

If you add this to the local I2C bus, you might as well add that
floating point co-processor at the same time.

Re: [oopic] Providing a clock/time to the PIC

The oRTC can make this a little simpler, but you'll still have some
accuracy issues. Look at the oTimer options which include the ability
to put a 32.7KHz crystal on an IOline and get a real RTC signal for the
oTimer output. However, you'd have to write your own functions to
decode it, it will be closer to correct for time for a longer time.
Note, to keep the RTC in proper sync you cannot interrupt power to it.

Re: [oopic] Re: Question regarding bootloader

The key item of note is that if you plugged the dongle into a different
USB port everything that you had set up before would be lost. The
drivers are irritating that way.

Since you only have bytes, unsigned words and integers, trig function
can be a challenge. No floating point, no extended precision and,
worse, no speed.

The way to get around this?

Just use an external co-processor.

I would think the oRTC object would be best suited for your purpose. It
is an object that maintains a real-time clock. It's been a few years
since I last played with this object but I do remember that it was
accurate to about 2 sec in a 24 hour period.
Also it will lose its current state when power to the oopic is interrupted.

[oopic] Providing a clock/time to the PIC

Hi guys, i got a question. As i am dealing with solar tracking
device, i would like to be able to feedback the time to the PIC. i
look through the object list and found several options that i could
use. Thought i just ask if there is any shorter way of doing it.

What i need:
Implementing a "clock" by using counters, using the execution cycle
and frequency of the PIC (in this case ooPIC is 20MHz). I would

counter_sec++;
if counter_sec == 60
{
counter_min++;
counter_sec = 0; 'resetting it back to 0
}
if counter_min == 60
{
counter_hrs++;
counter_min = 0; 'resetting it back to 0
}

if counter_hrs == 24
{
day++;
counter_hrs =0; 'resetting it back to 0
}

Loop

My question is will this code work?
how do i make this function keep on running outside the main function
Is this a good way of "telling" the time? Cos my device is a
standalone kind so no PC/Laptops will be connected once its configured

In the object list, there are oTimer, oCounter, oClock, are these
suited for the purpose? I looked thru the example, but i dun quite
get it. >.<

Anyone got any hints to how i might make this thing work?

Thanks once again

Turns out I was given incorrect information and it was on a different

When that happens, just go in to Device Manager and force it back to
whatever comm port number you want it to use. Then you can plug the
adapter in to any USB port and it will always have the same comm port number.

I too have followed Richard's methods when adding a USB/serial port

I find that when I plug my Gold-X USB-> serial adapter into a
different USB port (even a different port on an external hub) I get
prompted to install the driver! Over and over...

If I plug my external hub with serial adapters into a different USB
port on the PC, I get to start all over again. EVENTUALLY, I will
have installed the driver for every combination.

As I start to use USB for serial, cameras, USB uC chipsets and other
things that WinXP doesn't automatically identify, the process becomes
long and boring.

In the end, it works...

I have found that it is necessary to always use the same physical USB
port for my USB to Serial adapter. If a different physical USB port is
used then a different comm port will be assigned. This can also happen
if a different make of adapter is used to the one which was originally
used when mapping the comm port.

Hey Richard. Thanks. That actually did work. I changed the port
assignment, despite the warnings from the OS, and the change took
place ok. I didn't even have to reboot. In addition, oopic IDE v.6
was able to find the serial cable alright, since it was now <= COM6.
I'll try the rebooting next to see if it stuck.

Go ahead and select a port that is '(in use)' like COM4. I wouldn't
select COM1 or COM2 if they physically exist on the computer as
hardware serial ports or internal modems. Up comes a dialog
complaining about the conflict. Click on Yes to confirm your choice
to hose your system.

Then close things out and reboot. The USB port will be reassigned
when Windows restarts.

I know this works because I just changed a USB->Serial adapter on
COM13 to COM4 which was in use but not connected.

With Hyperterminal, the USB->Serial adapters don't always connect on
the first time HT is started. It isn't unusual for me to have to
close the instance and start it over.

Yes, been there, done that. For whatever the reason, on my computer,
every comport below #9 indicates already in use, even though nothing
is connected to the USB ports. I cannot select a comport value in the
oopic IDE range.

Right click on My Computer and select Properties
Select the Hardware tab and click on Device Manager
Right click on the COM port of interest and select Properties
Select the Port Settings tab and click on Advanced

There will be a drop-down list at the bottom of the dialog that shows
the current COM port assignment. Select a COM port number that is not
in use.

There may be a LOT of COM ports that indicate '(in use)' and you know
they don't exist. These are remnants of USB VCOM ports that are known
but not active. The COM port numbers may be reused if necessary. In
my case there are about 20 VCOM ports left over from various projects.

For V5 of the IDE, the COM port must be 1,2,3 or 4. Other ports may be
used with V6.

If you are unsure about WHICH USB port to deal with, unplug it and the
device will disappear from the list in Device Manager. Reconnect the
USB device and it will reappear in the list.

All of the above applies to WinXP.

Re: [oopic] first time use

What ooPIC are you using? The ooPIC R will have the IOLine labeled as
the actual IO line, the ooPIC S boards you need to cross-reference the
IOline to the physical pin.

above what the oopic IDE can handle. When I use control panel, there
are so many USB ports shown, I am also unsure what is going on.

In the end, the easiest way I found to determine the actual COMPORT
value is to use a 3rd party program. I am using the XCTU program
which is intended to work with Maxstream modems. :) It always seems
to find the correct comport automatically. Available on
maxstream.net, and I have a copy here.
