Fast library for SSD1963 LCD

Library for SSD1963 LCD with 16-bit interface:

[/URL]
LCD is 3/5V compliant.
Library works in Submode = New, so its very easy to include in project and unused Subs are not compiled to save memory space.
Also to save space you may use reduced Fonts, like Font36x56 in example. It has only digits, placed at position 33...42. To correct this shift simply use Digit_font = 1.
Any Fons may be included via $include. Supports both types of BASCOM Fonts - "Color" and "B&W".
You can display 8-bit (BGC) and 16 bit (BIN) pictures. Also 16 bit pictures can be loaded from SPI-Flash ROM. To prepare bin-file from bmp, gif, jpg, wmf, emf, ico I wrote special program Pic2Bin.

Library is fast. I specially made it to work quickly. In this video test program working at 8MHz. However, display resolution is 800x480 and its better to use 16MHz or 32MHz (Atxmega).

Thank you MrShilov for your hard work and sharing the Bascom code for the SSD1963 color display.

I have not programmed color displays with XMega chips.

1. Do you have an idea of how difficult it would be to modify the code posted here to work on XMega?
2. Would the touch-screen routines be similar to the ones posted for the SSD1289 display?

Any help or advice you have would be greatly appreciated. Based on your (or others) feedback, I will decide to purchase additional XMega chips.

well done ! This is a big display ! And it still works smooth. Love the YT videos Very Happy

I had no idea there were so many different graphical chips. Keep up the great work.

this code need small adjustments for xmega.
For example :
Dim Color_h_ssd1963 As Iram Byte At 22
Dim Color_l_ssd1963 As Iram Byte At 21

These are registers R21 and R22. The xmega can not linear address these registers. But you can use bascom SETREG statement. Or use some asm with STS.

Always nice to see that big parts of my code is re-used.

Thanks for sharing your code.

Sorry i can't read that, i'm not that good in my Russian.

It was meant as compliment, i'm glad that a lot of people using (parts) of my code and share the code that they made also with the Bascom community.

Thank you Mrshilov and everyone else for sharing your hard work! This library is great, much faster than previous examples. I am running an ER-TFTM070-4 display on ATMega645A @ 16MHz. I swapped Mrshilov's initialization values for my own (based on the sample code provided by the manufacturer) and it works well with one problem:

Display is upside down and color is in BGR mode, but control register Set Address Mode 36h has no effect on the screen! In my old routine I can change Set Address Mode 36h to flip display in any orientation and change the color mode. With Mrshilov's routine, no change! Only difference I can tell is Mrshilov uses submode=new while my working routine uses old submode.

I could fix this by flipping the screen around and changing the color constants to BGR, but that feels like a hack job Razz

. Does anyone have some insight?

Thanks again for sharing.

Hello Mark, MrShilov, GrainyPCB, (and others)

Trying to make the SSD1963 (480x272) LCD work with a XMEGA192A3 using the library INC file posted by MrShilov.

After spending quite some time, I cannot see any function on the LCD.

The pin-out for the LCD and my modifications to the library to accommodate the XMEGA are attached.

Any help or suggestions would be greatly appreciated - and also what to do with pins F_CS and REST.

try to use some other port than portA. i have pulled some hairs a week ago when doing an oled driver. the odd thing was that porta worked, and that i could toggle all pins, but that for some reason it did not work as normal. had no time to check on that, but using another port worked out fine.
further i can recommend to use a virtual port for these signals. config vport. for data this is not required but for control signals it is best.

if that does not work, i can have a look at the code.

Hello Mark,

Somewhere between your advice NOT to use PORTA, re-reading MAK3's AN#192 for Virtual Ports and comparing my code to that of the WIKI 7 Inch SSD1963 Display, I now have the display working.

But, as pointed out by GrainyPCB, my display too shows text to be upside-down/backwards. Maybe these are Chinese right-to-left displays??? ;)

Thanks for your help and motivation.
