Fast library for SSD1963 LCD

Ennio,

Look in the SSD1963 datasheet for control register 36h. You should be able to change this setting in the initialization routine to fix your rotation/orientation issues. I need &h09 for my setup. My current problem is one version of code I'm using accepts changes in this value and Mrshilov's doesn't. Still working on it...

i found nothing odd in your code. except that you have different init code at some places. but that is most likely because you have a different lcd.
so it is good you got it to work. the register settings indeed hold the key to these problems. good luck!

I figured it out. Many of Mrshilov's subroutines change the Page/Column Address Order of the 36h register, for example:

Thanks GrainyPCB.

I had worked with that same register &H36 ... but the routines prepared by Hipnik, Six1 and MrShilov defaulted to having the screen start (X,Y)=(0,0) at the lower right corner of the LCD (when viewed in landscape mode) on my LCD. This was confusing.

So, to have the BMP photograph files and text show correctly - at least on my 480x272 LCD - the LCD initialization needed this:

About the color BGR instead of RGB...

Do a search in the German Bascom-forum. I put there this note, but there was also a note from Heiko aka HKipnik about reversing the colors.

Hallo,
es gibt einen Fehler in der Sub LCD_text und Sub Lcd_text_color

im Register H2B wird das H- Byte nicht geschrieben
der Text wird ab Zeile 240 abgeschnitten.

Hier ist der ergänzte Codeabschnitt, danach läuft alles ohne Probleme

Data_disp_low = &H2B : Rs_disp = 0 : Wr_disp = 0 : Wr_disp = 1 '------ Y
Data_disp_low = Temp_y_ssd1963_h : Rs_disp = 1 : Wr_disp = 0 : Wr_disp = 1
Data_disp_low = Temp_y_ssd1963_l : Wr_disp = 0 : Wr_disp = 1
Data_disp_low = 1 : Wr_disp = 0 : Wr_disp = 1
Data_disp_low = &HDF : Wr_disp = 0 : Wr_disp = 1
Data_disp_low = &H2A : Rs_disp = 0 : Wr_disp = 0 : Wr_disp = 1 '------ X
Data_disp_low = Temp_x_ssd1963_h : Rs_disp = 1 : Wr_disp = 0 : Wr_disp = 1
Data_disp_low = Temp_x_ssd1963_l : Wr_disp = 0 : Wr_disp = 1
Data_disp_low = 3 : Wr_disp = 0 : Wr_disp = 1
Data_disp_low = &H1F : Wr_disp = 0 : Wr_disp = 1
Data_disp_low = &H2C : Rs_disp = 0 : Wr_disp = 0 : Wr_disp = 1
Rs_disp = 1

Super Arbeit von Mrshilov

Thank you. I found more errors in SSD1963 library, also in SSD1298 & ILI9325. I will publish updated libraries soon.
It will be with "Landscape/Portrait" mode, TouchScreen examples and Proteus models.

Hi

Can i please ask the xmega gurus for some help making this superb code work on xmega.

I have a Xmega128A1, everything looks good, but when it comes to SD-card i get errors when compiling.
It says unsupported comand or something in that direction.

In the TestSSD1963.bas:

' For load Pictures from SPI-ROM you must configure SPI:

Config Spi = Hard , Interrupt = Off , Data Order = Msb , Master = Yes , Polarity = High , Phase = 1 , Clockrate = 4 , Noss = 1
Spsr.0 = 1 : Spcr.0 = 0 : Spcr.1 = 0 'F_spi = F_osc / 2
Ss_spi_rom Alias Portb.6 : Config Ss_spi_rom = Output : Ss_spi_rom = 1 'Chip Select pin
Spiinit

And in SSD1963 16bit Library.INC:

'-------------------------------------------------------------------------------
' Draw 16-bit Picture from SPI-ROM
' X start - Y start - Width - Height - Address
'-------------------------------------------------------------------------------
Sub Lcd_pic_spi(byval Xs As Word , Byval Ys As Word , Byval Width As Word , Byval Height As Word , Byval Address As Dword)

Temp_x_ssd1963 = Xs + Width : Temp_y_ssd1963 = Ys + Height
Decr Temp_y_ssd1963 : Decr Temp_x_ssd1963
Data_disp_low = &H2A : Rs_disp = 0 : Wr_disp = 0 : Wr_disp = 1
Data_disp_low = High(xs) : Rs_disp = 1 : Wr_disp = 0 : Wr_disp = 1
Data_disp_low = Low(xs) : Wr_disp = 0 : Wr_disp = 1
Data_disp_low = High(temp_x_ssd1963) : Wr_disp = 0 : Wr_disp = 1
Data_disp_low = Low(temp_x_ssd1963) : Wr_disp = 0 : Wr_disp = 1
Data_disp_low = &H2B : Rs_disp = 0 : Wr_disp = 0 : Wr_disp = 1
Data_disp_low = High(ys) : Rs_disp = 1 : Wr_disp = 0 : Wr_disp = 1
Data_disp_low = Low(ys) : Wr_disp = 0 : Wr_disp = 1

For Count_x = 1 To Width
Spiin Temp_x_ssd1963 , 2 'Read 2 bytes from ROM
Data_disp_high = Temp_x_ssd1963_l : Data_disp_low = Temp_x_ssd1963_h
Wr_disp = 0 : Wr_disp = 1
Next Count_x
Next Count_y
Ss_spi_rom = 1 'deselect SPI-ROM
Ssd1963_select_reg &H36 'Normal X/Y order
Ssd1963_write_data &H23
End Sub

Am not the best programmer so i hope someone can take a few minutes to help me.

Best regards

i did not test but i think you only need to replace the config spi with : Config Spic = Hard , Master = Yes , Mode = 0 , Clockdiv = Clk2 , Data_order = Msb
then use the SPI from portC to get default SPIC.

An example with an atxmega128a1, an 7 inch display and sd-card can be found in the wiki. The Sd-card of the atxmega128a1 module is used...

Have fun

Prerelease of new library.
With "Portrait" and "Rotate_180" constants may choose any of 4 possible positions of LCD.
Added "Brightness", "Contrast" and "Saturation" commands.

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

Many thanks for your examples!!!

Hello im new in this post, i would like you please help me im using a screen INT070ATFT - TS it uses a microcontroller SSD1963 and for touch screen uses a MAXIM MAX11802. After some tries i finally got my lcd showing pictures from an external sd card. Now im trying to use the touch panel but after some tries i cant get anything. The controller for the touch screen uses spi interface plus has an interrupt. I press the screen and the interrupt is not working. I dont know what to do, i would like u please provide me a code for initialization of the maxim and code in order to use the screen

thank you waiting for ur answers
