[Problem SSD1963 and STM32F4 Discovery]

Did you read this tutorial http://www.chibios.org/dokuwiki/doku.php?id=chibios:guides:eclipse2 ? I created my first programs in ChibiStudio using makefile and demo projects.

Hi dimky!

Unfortunately, I stopped working on this project over 1,5 month ago. Now, I see that there is a huge mess in files, so I think it won't help you

But you can decribe your problem here and we would try to help.

Yes, it works. You're great! Really thanks for support.

If anyone can help with second question please write.

Hi,

I need help with this function. Can somebody write simple example how to use it? I know that it isn't too hard but I have problem with this :oops:

And another question. Can you recommend good font converter with compatible format to uGFX (32 px height).

I' m really thankful for yours help

Hi mobyfab,

On 16 bit evertyhing works fine, but I tried to run 18 bit. Why it isn't possible on FSMC?

[Problem SSD1963 and STM32F4 Discovery]

I have changed this

/* Screen size */
	write_index(SSD1963_SET_GDISP_MODE);
//	write_data(0x0000);
	write_data(0b00011000); //Enabled dithering
	write_data(0x0000);
	write_data(mHIGH((GDISP_SCREEN_WIDTH+1)));
	write_data((GDISP_SCREEN_WIDTH+1));
	write_data(mHIGH((GDISP_SCREEN_HEIGHT+1)));
	write_data((GDISP_SCREEN_HEIGHT+1));
	write_data(0x0000);

to this

	/* Screen size */
	write_index(SSD1963_SET_GDISP_MODE);
	//write_data(0x0000);
	write_data(0b00011000); //Enabled dithering
	write_data(0x0000);
	write_data(mHIGH((GDISP_SCREEN_WIDTH-1)));
	write_data((GDISP_SCREEN_WIDTH-1));
	write_data(mHIGH((GDISP_SCREEN_HEIGHT-1)));
	write_data((GDISP_SCREEN_HEIGHT-1));
	write_data(0x0000);

and it works perfect. However I wolud like to use 18 bit color, but when I turn it on I get red color instead of black. On 16BIT565 everything is fine.

Now it works! Thank you resset! I have only changed these FSMC dealys.

EDIT: But I still have three multicolored lines on right side

Hi,

I have lately bought LCD panel like this http://www.ebay.com/itm/7-TFT-LCD-Modul ... 0963914141 but I can't make it work properly . The image is completly jagged. I rode this topic http://forum.chibios.org/phpbb/viewtopi ... =11&t=1133 but it didn't help. Panel is connected through 20 cm wires. I'm using FSMC.

My gdisp_lld_panel.h

/* The timings need to follow the datasheet for your particular TFT/LCD screen (the actual screen, not the controller)
*** Datasheets normally use a specific set of timings and acronyms, their value refers to the number of pixel clocks
** Non-display periods refer to pulses/timings that occur before or after the timings that actually put pixels on the screen
** Display periods refer to pulses/timings that directly put pixels on the screen
HDP: Horizontal Display Period, normally the width - 1
HT: Horizontal Total period (display + non-display)
HPS: non-display period between the start of the horizontal sync (LLINE) signal and the first display data
LPS: horizontal sync pulse (LLINE) start location in pixel clocks
HPW: Horizontal sync Pulse Width
VDP: Vertical Display period, normally height - 1
VT: Vertical Total period (display + non-display)
VPS: non-display period in lines between the start of the frame and the first display data in number of lines
FPS: vertical sync pulse (LFRAME) start location in lines. 
VPW: Vertical sync Pulse Width

*** Here's how to convert them:
HPS = SCREEN_HSYNC_PULSE + SCREEN_HSYNC_BACK_PORCH
HT - HPS = GDISP_SCREEN_WIDTH + SCREEN_HSYNC_FRONT_PORCH
=>    SCREEN_HSYNC_FRONT_PORCH = ( HT - HPS ) - GDISP_SCREEN_WIDTH
   SCREEN_HSYNC_PULSE = HPW
   SCREEN_HSYNC_BACK_PORCH = HPS - HPW
   SCREEN_HSYNC_PERIOD = HT

VPS = SCREEN_VSYNC_PULSE + SCREEN_VSYNC_BACK_PORCH
VT - VPS = GDISP_SCREEN_HEIGHT + SCREEN_VSYNC_FRONT_PORCH
=>   SCREEN_VSYNC_FRONT_PORCH = ( VT - VPS ) - GDISP_SCREEN_HEIGHT
   SCREEN_VSYNC_PULSE = VPW
   SCREEN_VSYNC_BACK_PORCH = VPS - LPS
   SCREEN_VSYNC_PERIOD = VT

Some photos:

1. Image demo

2. Text demo

3. Basics

Please don't look at the colors, I have fixed them (RGB to BGR). But I still have pixels in random places or I haven't in other (for example ragged diagonal line or multicolored lines on right side on third image ).

LCD datasheet is available here: http://propix.com.pl/pl/p/file/ec1058c5 ... 2_PV02.pdf. Please help me with it.

PS. Sorry for my bad English.
