Anna's Sandbox

Welcome to Anna's Sandbox!

This is the place where I will post my current 4D systems projects, and where you are also welcome to post yours. The projects might be just an idea for now, be in a half-finished state, or complete with documentation.

The idea is to share how to do things the 4D way - someone out there might already have the solution to our problem, or we might have a solution to theirs!

Hope you enjoy this thread.

problems with gfx_bitmap

Kirill_rf — Fri, 06 Nov 2009 19:47:25 GMT

I want to use gfx_bitmap to draw bitmap graphics for fast picture displaying at uOLED 32028P1. I looked through the suggested examples in 4DGLworkshop, but still I don't completely understand how it works. In particular, I wonder how to declare my own bitmap picture using #DATA blocks. Could someone give more information or better examples of using gfx_bitmap?

Putting Font(s) on uSD and using them.

mhuett — Fri, 06 Nov 2009 14:01:44 GMT

Still finding navigating the multiple documents/help files/web pages a bit frustrating ... but my project is coming along quite nicely so far.

One issue I'm stuck on at the moment is how to put *.4DFont files onto the uSD and then using them.

I use Graphics Composer to set up my images and then 4DGL Workshop IDE to send them to the uSD ... I can access any of those either direct via programming or via serial... no worries

I have edited some fonts which I want to put on the uSD (read somewhere that you can!!) ...but can't work out how to do it. Putting then in as DATA in the program works but it takes up valuable space...

How do I get the font file(s) onto the uSD (preferably via my uUSB-CE5) without it overwriting my image files ... and once they are there how do I access them??

Thanks in advance

When will be mode 2 of file_LoadImageControl supported

thomasW69 — Fri, 06 Nov 2009 10:32:41 GMT

in the current 4DGL I find the following

Quote:

mode 2 :
Note!!! mode 2 is not yet supported.
If mode is 2, it is assumed that the image offsets provided in "fname1.dat" are the abolute sector addresses of the images stored in a raw partiton (ie:- the long address of the image stored as consecutive sectors in its own partition, hidden from FAT16 on the uSD card). In this case, "fname2" is just ingnored (pass as a 0 or "") as we already have the direct sector addresses in the partition that have been provided by "fname1.dat" and don't require a file to be opened to retrieve the images.
The sector address map ("fname1.dat") will be created with a future version of Grapics Composer, and the uSD card must be loaded directly by Graphics Composer. This is a non-portable format, but is the fastest way to display images, animations and videos from the uSD card as there is no file system involved, and image frames are stored in consecutive sectors.

When will this be supported?

When will be the next 4DGL Version released that was announced since half a year?

Can my old uOLED128G1 be upgraded to (GFX)? So, I can use 4DGL2
Just download uOLED128G1GFXR19.pmmc?
Or, I have to purchase a new one?
Thanks.

howto put LCD in shutdown

manes6969 — Thur, 05 Nov 2009 17:15:15 GMT

Hi

I have a LCD 32032P1T which I want to put into sleep mode consuming the lowest current. How can I do this ? I'm using the SPE_alpha01.4dg file which I adapted to my needs , but using a backlight off , a power down and contrast to 0x00 still consumes about 100mA !!!
I think this could be much less , saying a few mA's ?
I also read somewhere that the used controller is a ILI9320 so I added this code from their app note :

display_SetReg(0x07,0);             //Power down the lcd into deep sleep mode
            display_SetReg(0x10,0);
            display_SetReg(0x11,0);
            display_SetReg(0x12,0);
            display_SetReg(0x13,0);
            pause(200);
            display_SetReg(0x10,2);

But still same result

Who can help me on this ???

Kind regards ,

Just a couple of sources for 'Royalty free' fonts I've come across on the web.

Check each font first though, some have 'unusual' requirements.

Range check error in DISP

nevernamed — Tue, 03 Nov 2009 04:17:42 GMT

Hi everyone, has anyone had this error or know how to fix it?

I am working with a uLCD-32032-P1T with the uLCD-32032-P1TSGC-R11.pmmc file loaded through the PmmC Loader utility. The FATcontroller communcation works fine.

When I try to Load from Display using the DISP utility, the progress bar goes up to 100% but then I get this range check error:

I'd really like to make some modifications, like change to landscape and add some fonts, but I'd rather not have to start from scratch. The Load From File option also doesn't work using the .h files from the website. It says Data in file not expected size(0<>6144)

Any Help and Suggestions Welcome

goom — Tue, 03 Nov 2009 03:46:29 GMT

I recently bought a SOMO-14D with the objective of developing sound modules for RC model boating. Unfortunately I have failed to actually get it working.
I have tried bit-banged SPI via a PICAXE-18X, using my own code and also that posted by tristronics (with minor adaptation to suit my microcontroller). I have also tried reverting to the key-mode mode, all to no avail.
My setup is:
power - 5V regulated through 2 x 1N4001 diodes
2GB micro SD (SNK2GB0906, TAIWAN) from a Blackberry. Reformatted in FAT16, just to be sure
3 files 0000.ad4, 0001.ad4, 0002.ad4 of 1, 2 and 30 seconds respectively. I have read back these files and reconverted them to .wav. They are then playable on my PC, so conclude that the .ad4's are good.
32 Ohm speaker across pins 11 and 12, or an audio amp. on pin 14.

After sending a command (serial or key mode), the SOMO-14D responds with a high on the BUSY line of about 1/2 second, but does not play the sound file. I do hear a faint couple of clicks, but that is all. I have also played with the volume, play/pause and stop commands with the same result.
So, I conclude that data is being received, but the sound file is not being retrieved and decoded. The faint clicks would indicate that the sound output pins are active.
Could the micro SD be incompatible for some reason?

Any help or suggestions would be most welcome.

Mixing FAT and RAW accesses

marcwolf — Tue, 03 Nov 2009 01:20:13 GMT

Hi
I am working on part of a project and I need a little help.
I have created a series of animatronic sequences which will be read and passed to a servo controller. These sequences have a build in command structure that will allow Loop X times, Jump back to X etc.

I need an easy way to write this large file onto a 64mb SD card. I can do that using FAT16 with no problems.

However I need to then read this file in a PicAXE environment. I can open the file in FAT mode and read in X bytes at a time, however I cannot then jump back X bytes.

If I use RAW mode then I have more control over the pointer and can skip back 300 bytes if necessary. However it them makes it much more difficult to initially write this file from the PC.

However.... If I know the starting point of the file on the SD drive then I can save it using FAT, and then jump to the starting point using RAW mode and read it that way.

So.. Can anyone tell me a quick way to find the first byte of a file (or data area as there will only be 1 file) on a SD ram card.
If really worst comes to worst I can save the file and then use a disk editor to look for its start and get the byte count - but an eaier way would be great.

Bonjour,
Just one question (may be stupid ?):
My memory card is formated (FAT16).
If I turn OFF the FAT protection, can I write byte data, (with the @w command) from the beginning of memory (ie: from adress 00:00:00:00) ?

OLED-128-G1 COM0 serial guideline

muth — Mon, 02 Nov 2009 03:42:52 GMT

Hello

First, I have to say that I'm really impressed by this product. The hardware and the software behind. So thanks a lot 4Dsystems!

I have a project to use the OLED-128-G1 to communicate with the electronics of my motorbike. It's a serial rs232 communication, 9600 baud, 8 bit, TTL levels, etc, Exactly the COM0 port.

The communication is done by sending a 9 bytes request, and bike reply instantly around 100 bytes with useful information.

My question is witch strategy use to write that. I'm using the 4DGL language only from few days.

I think I have to use buffered serial input, like shown on the "gfx2_SerialBuffered.4dg" example. I think I understand this process.

But I have no idea for sending the request bytes sequence. Do I have to use hard code like

to(COM0); putch(0x0F);

to(COM0); putch(0xD2);

...

to(COM0); putch(0x5F);

Or how use a #DATA bloc like

#DATA

Byte req 0x0F, 0xD2, ..., 0x5F

to(COM0); print( req , req , ..., req ,);

Is a nicer buffered output method exist ?

Thanks a lot, and sorry about the dirty English.

Pierre
