Hello

recently i have bought LCD TFT 2.8 with interface GPIO 8 bit, resolution:320x240, sc card, driver ILI9341 V0.7
https://www.google.pl/search?q=ILI9341+V0.7+arduino&source=lnms&tbm=isch&sa=X&ved=0ahUKEwjgzMXUpcfbAhXHtRQKHQieDS4Q_AUICygC&biw=1316&bih=743#imgrc=LkngZVt5BMqQnM:. It is connected directly to the arduino UNO

and because I have almost not experience with lcd my question would be:
- is there something for such display (ili9341 8-bit) in Bascom?
- which or how use ili9341 8-bit, maybe someone could share an example or give some link?

Thanks

Martin

(BASCOM-AVR version : 2.0.7.6 , Latest : 2.0.8.1 )

I get driver from this thread:
https://www.mcselec.com/index.php//index2.php?option=com_forum&Itemid=59&page=viewtopic&t=14087&highlight=ili9341
and now I try to adapt it to the Arduino UNO. So I have few questions:

1.

in ili9341_declarations8.inc there is:

Quote:

Config Portd = Output
Data_disp_low Alias Portd \'DB0 --> DB7


but this lcd shield use also portb (0,1) and portd (2,3,4,5,6,7) so my declaration is:

config PORTD.2 =output
config PORTD.3 =output
config PORTD.4 =output
config PORTD.5 =output
config PORTD.6 =output
config PORTD.7 =output
config PORTB.0 =output \' not portd
config PORTB.1 =output \' not portd

and question is how to declare Data_disp_low alias (portd and portb) ?

2. i got during compilation such error:

Quote:
Error : 242 Line : 728 Source variable does not match the target variable [ 0|RGB8TO16(PIXEL)] , in File : TFTDriver\\ILI9341_functions8.inc
but checked this line and it sems Ok, so why this error?

Thanks

Martin

In "ILI9341_declaration8.inc" config pins as follow:
Code:
' Data ports
Data0 Alias Portd.2 : Config Data0 = Output                
Data1 Alias Portd.3 : Config Data1 = Output                
Data2 Alias Portd.4 : Config Data2 = Output                
Data3 Alias Portd.5 : Config Data3 = Output                
Data4 Alias Portd.6 : Config Data4 = Output                
Data5 Alias Portd.7 : Config Data5 = Output                
Data6 Alias Portb.0 : Config Data6 = Output              
Data7 Alias Portb.1 : Config Data7 = Output


In "ILI9341_functions8.inc" make subroutine:
Code:
'-------------------------------------------------------------------------------
' ILI9341_set_port       Set 8 Bit Data Port
'-------------------------------------------------------------------------------
Sub ILI9341_set_port(byval Data8 As Byte)
   Data0 = Data8.0
   Data1 = Data8.1
   Data2 = Data8.2
   Data3 = Data8.3
   Data4 = Data8.4
   Data5 = Data8.5
   Data6 = Data8.6
   Data7 = Data8.7
End Sub


And replace each string
Code:
Data_disp_low = XX

with
Code:
ILI9341_set_port XX


For details see example of using Arduino Uno with HX8352B display in attachment.
