Copy Display to Screen

Wed, 16 May 2012 21:46:17 GMT

This seems like such an obvious thing that if it's a real problem, someone else would have noticed it before. Running with uOLED-96-G1(SGC) and 4D Programming Cable.

On the "Tests" tab, "Copy Screen to Display" works perfectly. "Copy Display to Screen" does something weird -- it almost looks like it has the screen aspect ratio backwards, so that it copies two 96 pixel lines of data into three 64 pixel lines. In an case, the data is only loaded into the left-hand square area of the on-screen image, so I can't collect an image created on the device and save it to a BMP, for example.

An easy test for this: I have an full-screen image (96x64) that I loaded at sector 0x20000. I can run Raw SD: Copy Memory Card to Screen, and it shows up great (on the device). Then I run Copy Display to Screen and get weirdness. If I follow up with Copy Screen to Display, the weirdness is now duplicated on the display.

Am I just missing a setting somewhere?

LabVIEW drivers for uOLED modules (SGC)

Wed, 16 May 2012 18:44:11 GMT

Hi - Sorry if it's bad form to post into multiple forums, but I think it's relevant here too.

I've written a bunch of LabVIEW drivers and examples -
http://www.ktizo.co.uk/4D-systems-uLED-Drivers.php

They don't cover all the functions by any means, but there's enough there for a LabVIEW developer to get some good ideas hopefully.

They were developed using the uOLED-160-G1 (SGC) but ought to work with any of the SGC modules, with a bit of tweaking.

All free to download and use in non-commercial applications! (Contact me for commercial applications)

Enjoy - and feedback welcome (just remember they're free though!)

Advice on way to display image on the fly

Wed, 16 May 2012 10:13:12 GMT

Hi,

I have recently bought a uLCD display. I want to display an image on the fly, that is it's created by an external app and sent to the uLCD.

The options are (i cannot use the Graphics Composer):
- Use the SGC mode and the DrawPixel serial command as to display the image pixel by pixel
- Use the GFX mode and send the data to the LCD over serial, stored it on the sdcard or in memory with the format from here, and the using GFX commands display the image.

I don't mind that there is a delay, but I don't want the screen to be flickering while refreshing the image.

Which option is better? In case GFX is is possible to store a image in memory as to avoid writting too many times in the sdcard?

No Audio (just click)

Wed, 16 May 2012 07:32:35 GMT

Hello Everyone!
I recently purchased a SOMO 14D in hope of having a reliable embedded sound system for my robot project. i had some trouble with the utility tool but it appears to be working fine. i have purchased Kingston,PNY, and Sandisk 2gb microdrives, formatted each of them with similar results. that is a faint high pitch then a regular click(pulse?) noise. I have tried changing the sampling rates from 6000 to 32000.
Any suggestions?

[POGA] Font set

Tue, 15 May 2012 17:07:05 GMT

Hello,

I'm trying to find out the equivalent printable char for 127 that on my poga appears as a solid dot.

So my question is, what is the character so I can write print("single_character"); and obtain the same result as print( 127);?

If I write: print( 127);

it works, but if I use the equivalent ascii print("|"); where the vertical line is the 127th character it doesn't work!

Many thanks to all!

How to create .4FN files

Mon, 14 May 2012 14:10:28 GMT

Hello,

1. i'm trying to load some of my code functions dynamically to RAM as i ran out of code space, but I can't figure out how to create .4FN files via workshop or any other way that works.

2. Some additional questions.

a) Can i access global variables from the parent program in the .4FN functions without passing them as arguments?

b) In the internal func rev I find this example:
popupWindow := file_LoadFunction("popupWindow1.4fn");
...
res := popupWindow(MYMODE,titlestring,textstring);

is it a coincidence that the function name in the function call is the same as the variable name the file_LoadFunction pointer got assigned to? To clearify the question: Is in the popupWindow1.4fn a function called popupWindow(var 1, var2, var3) and probably more functions than just that one, or is there just one function which gets called via the variable name file_LoadFunction gets assigned to.

So would this two example statements be equal without changing the popupWindow1.4fn or not?

Quote:

popupWindow := file_LoadFunction("popupWindow1.4fn");
...
res := popupWindow(MYMODE,titlestring,textstring);

Quote:

popup := file_LoadFunction("popupWindow1.4fn");
...
res := popup(MYMODE,titlestring,textstring);

c) Is it possible to load more than 1 function out of a .4FN file?

Thanks in advance

Remove char from onscreen text

Mon, 14 May 2012 09:59:27 GMT

What I'm trying to do is to remove a char from a string on the screen as so:
from 1234 to 123.
With opaque enabled I can overwrite the '4' with ' '. This works fine. But with opacity set to transparent, the ' ' isn't drawn, so the '4' remains.

So my question is, how can the char be removed from the screen with transparent opacity and without refreshing the whole screen?

Setting brightness using DISP?

Sat, 12 May 2012 12:21:05 GMT

Hi,

I have some µLCD-32PT(SGC), and I have noticed a difference with the brightness and colour of the displays. I checked the documentation for this unit and it says I can change the settings in each display using the DISP tool.

I cannot find any documentation on what setting changes the brightness. There are several setting in the software but some have their own special tokens that isn't documented or explained in the software. Can you help me?

µLCD24PT landscape Disp config

Sat, 12 May 2012 10:34:39 GMT

I have two µLCD24PT.
I need a landscape orientation and pictures .

The old one has a OTM3225 Driver IC. I downloaded the corresponding landscape DISP file (uLCD-24PT-L-V00.h) .
-> problem solved

The new one has a ILI9325 Driver IC . There is only one DISP file available.
How do I change the orientation ?
Thanks
