What is it that you need?

(Also, I'd delete the duplicate message in BASIC STAMP. Not only is duplication against forum policy, but it's off topic there.)


New to the Propeller?

"Sensors"? What type?What does the project do?

Your duplicate thread in the BASIC Stamp Forum has been removed. This forum is for Propeller Support so the soliciting information has been removed from the initial post. If you wish to hire someone rather than get assitance, please post in the Sandbox only.

Hello seedcorp,

we need more information.

Post the exact productnumber and producttype of the display
post a webadress where the datasheet can be downloaded

without this information the forum can't help

best regards

A small bit is missing... the datasheet for the controller ic.

This display apparently uses the RamTex SSD0323 chip. Google that and you find specs, C-code snippets, etc....

Hello seedcorp,

from your question I conclude that you are a beginner about propeller-programming
and how displays work.

In your attached datasheet "Pictiva2.pdf"

on page 4 Table : TAB Connection Pin Out

shows which cable-pin-number has which function.
this is some information about the "WIRING" of the hardware
but there is NO information about how the software-CONTROLLING is done
by using this wiring.

There is the display and some electronic-circuits that does the lowlevel-details
how to switch on/off all the 128 x 64 pixels. This is done by the controller-IC.
There are different types of controller-ICs. So without knowing the controller-type
it's not possible to communicate with the display.

within microcontrollers and displays it is NOT as easy as with any USB-device:
"plug-in - windows will automatically install the driver and your ready to use"

So we need the type of this controller-IC.

If you imagined that this display would work connect some wires to the propeller
write a program of 20 lines and everything is working. This is NOT the case with this kind of display.

You will have to learn a lot about how this controller-IC works.

If you want to have an easy way of programming i recommend buying a

prop-096 (http://www.dontronics-shop.com/4d-micro-oled-96-prop-096-propeller-powered-oled-module.html)

which uses already a propeller-chip

or any other graphical display with a RS232 serial interface

With modules like that it will be much easier to communicate.

best regards

hello seedcorp,

why inventing the wheel new ?

just buy a new Sparkfun Graphic OLED Color Display 128x128 (http://www.sparkfun.com/commerce/product_info.php?products_id=712)

and use the ready to use propeller-object

uOLED-128x128 Driver For SparkFun Carrier Board (http://obex.parallax.com/objects/404/)

best regards


I did some intensive searching about this SSD0323 controller IC

solomon systech seems to be informative only for big companies
(no datasheet download-section on the website)

My comment: if solomon does NOT want to sell products
go ahead to another company that want's to

It is time to discuss this with your teacher. You seem so lost; maybe you need to review the project requirements.

Not only that, but if you pay someone to do your schoolwork then you won’t learn and benefit from the experience.

I agree with this advice here. It will be much cheaper to get a display that has drivers written for it. If you can get started with something simple it shouldn't take too long to start making headway.

Interfacing with this display will not be easy given the sporadic info that I found on it. Anytime you have to guess whether or not there is built in dc\dc it is not good.

Hello seedcorp,

later - after school if you were working for a company your chief expects that you SOLVE the problems.

In most cases he will NOT be interested in details or a special solution. Most solutions are OK.

So what is EXACTLY your execise ?

Did I understand right: The exercise is to read in some sensors-values and show sensor-values on a screen ?

If this is the right description your chief will be happy if you can show him:

a.) just connect a standard-VGA.monitor to my sensorbox (containing the propeller) and see the sensor-values

b.) connect standard-television-monitor

c.) connect a 2x16 character display

d.) connect to a PC via a serial cable and a PC-Terminalsoftware shows the sensor-values

e.) Your chief will also be happy if you tell him at the RIGHT EARLY time:
"boss you thought it would be easy
I did a lot of researching - but the components you suggested are very complicated

I have found alternative solutions that are much easier (and therefore much cheaper)
which one would you like to be realized see solution a.) - d.)

By asking in this forum for a completed program: this is massive cheating !!!
It's NOT you who does the work and your teacher will see this by asking you questions how you programmed it
your answer will be: "ah - eh - hm ....... silence"

Be honest to your teacher and tell him about the alternatives

best regards

Can you post more detail on what you want to do?

You really need to talk with your teacher. If you are not getting it he should be able to help or at least give you an idea of what courses you should be taking.

Did you discuss with your teacher that you are not getting any help, see no prospects for getting help, and ask what you should do?
