STM32F103 and ILI9320 QTFT display

Posted on May 17, 2011 at 13:36

I think there are many others like me, looking for some ILI9320 8-bit code...

So isn't there a simple step to convert the 16-bit to 8-bit code?

I have found every command in the code to be 16-bit, so first of all, they need to be translated, as stated in the datasheet!

Also, where in the code is the pins, where the LCD is connected, defined?

Hi Mariem.

First I have to say that you don't have to post 3 posts with the same context, this won't speed up the process helping you!

About your problem, I haven't used ST's picture function, as I've made my own. You can check this thread for more information about that code and some errors with it:

Hi jj.sprague,

I'm trying to display images on the LCD screen (ILI9329) using an STM32F103ZET6, the problem that I couldn't display colored pictures, I used the ''LCD_WriteBMP function'' for that and I tried with monochrome pictures and it worked well using the ''LCD_DrawMonoBMP function'' which is provided for displaying monochrome BMPs.(these functions are from the demo's in the STonline)

Actually, I convert the images into an hex code using a software called the Hex Workshop then I put the image as a const

like this for example:

 const unsigned char IMAGE[] :{

0x00, 0xFF, 0xFF,  0x00, 0xFF, 0xFF, 

0x00, 0xFF, 0xFF,  0x00, 0xFF, 0xFF, 

0x00, 0xFF, 0xFF,  0x00, 0xFF, 0xFF, 

};

an then in the call of the function :

LCD_WriteBMP((u32) IMAGE);  // if it's a colored picture //

LCD_DrawMonoBMP((u32) IMAGE);  // if it's a  monochrome picture //

the monochrome picture displayed corretly but the colored one is not clear.

Please if there is any idea to help me I would be very gratefull.

Looking forward to hearing from you..

Best Regards
