I posted earlier about problems with larger fonts than font8x8.font. Here: http://www.mcselec.com/index2.php?option=com_forum&Itemid=59&page=viewtopic&p=68398#68398
There was an error in ILI9341_M328_revA.inc: in
Code:
Sub Lcd_text(byval S As String , Byval Xoffset As Word , Byval Yoffset As Word , Byval Forecolor As Word , Byval Backcolor As Word)
 
was a mix up between X and Y.
Code:

End Sub
 


Attached the updated library.

Hi,

I use display 3,2 inch with 16 Bit parallel mode (lib from Netzman ) and all work OK, but I can not get a larger font than 8x8.
SPI variant of lib have support for larger font.
Is it possible to use a text-routine from SPI lib (with some editing) for 16 bit parallel lib. I tried, but without success.

Please... help

Z. Dabic

Thank you...

Hello.
Link of the first post did not work.

Is it possible for the library to work with such a display?

Hello,

The connection scheme is online now.
the server has been moved again, during that process the images got lost (most of them I could recover, i've had at least the ones of the display library).

Best regards

Hello.
Help me anyone in the configuration file ILI9341.inc?
I want to run 16bit display mode under arduino mega 2560.
I do not know how to configure file .inc.
The arduino mega pins DB0-DB7 controls the port C pins and DB8-DB15 port A.
D / C is a pin PD7
CS to pin PG1
WR to pin PG2
RESET pin is PG0
Set somebody .inc file under such control and ATmega2560?

The problem is also with a sample program.
There is an error in this location:

' =========== Rotation ============
For Pixels = 0 To 4
Lcd_set_rotation Pixels <<<<<<<<---------------------------------HERE IS ERROR
Lcd_clear Color_white
Y = Lcd_screen_height - 20
Lcd_fill_rect 0 , Y , Lcd_screen_width , Lcd_screen_height , Color_black
Y = Y + 4
Statustext = "Rotation " + Str(lcd_rotation)
Lcd_tt_text Statustext , 10 , Y , Color_white
X = Lcd_screen_width - 80
X = X / 2
Y = Lcd_screen_height - 155
Y = Y / 2
Restore Hand
Lcd_pic_flash X , Y , 80 , 155
Waitms 1500
Next


Bascom gives this error:
Error: Line 71: 175 Different type parameter passed then DECLARED [PIXELS], in File: E: \ Electronics \ Bascom \ ILI9341 \ ili9341.bas
