Hello

everyone, I hope you are well.

I have a small

problem I would like to display a logo of my my university on board

STM32F429i_Discovery

but I sometimes displaying the logo ST.

I use LCD

image converter

but it does not work well to create my table to integrate it into the code.

I do not know

if ST used another converter. You can point me please.

I use BSP_LCD_DrawBitmap(...);

Thank you very much.

#stm32f429i #lcd #ili9341

Hm...

Try swap position of red and blue color parts in color matrix (Operations 2 and 3 on screenshot

https://my.st.com/public/STe2ecommunities/mcu/Lists/STM32Discovery/Attachments/16888/2016-09-16_21-41-png

from previous post).

Also try convert 3 images filled with one color: only red, only green, only blue.

I have STM32F429I-Disco, but I don't have working application with BSP to check my assumptions.

Then leader vladimir,

I just reverse the red and blue color as you told me, I had a yellow logo and after I tried every single green, red and blue alone. my result is in attachment.

I think it must be reversed between green and red

Ok, I have completed project with BSP and checking settings!

See attachments here.

BSP_LCD_Init();
BSP_LCD_LayerDefaultInit(1, LCD_FRAME_BUFFER);
BSP_LCD_SelectLayer(1);
BSP_LCD_SetBackColor(LCD_COLOR_WHITE);
BSP_LCD_Clear(LCD_COLOR_BLACK);
BSP_LCD_DrawBitmap(0, 0, 
reinterpret_cast
<uint8_t *>(&stlogo));
BSP_LCD_DrawBitmap(0, 70, 
reinterpret_cast
<uint8_t *>(&rect_blue));
BSP_LCD_DrawBitmap(0, 70 * 2, 
reinterpret_cast
<uint8_t *>(&rect_green));
BSP_LCD_DrawBitmap(0, 70 * 3, 
reinterpret_cast
<uint8_t *>(&rect_red));

I have described this in article

Thank you very much boss, you gave me much idea and I hope it will help others, you will have more tutorial on how to use the STM32 Embedded Wizard for display applications or broadcast video or sound. Thank you so much. Just a little trick to cast reinterpret_cast I do not have that C is used in only the C ++ it does not matter if I'm just (unit8_t *)? and what is the other method used instead of BSP? and why it is generating xml ? thank you very much

riuson · ‎2016-09-18

In ''C'' you can use

BSP_LCD_DrawBitmap(0, 0, (uint8_t *)&stlogo);

I'm not used LCD on STM32F4 before. So I'm not familiar with BSP, DMA2D and other features. On STM32F1 I'm using FSMC + DMA + external display controllers.

XML is using as internal storage format of this utility. You can edit image, save it to XML file, open later and continue editing.

Hello,

Do you have ever worked with

embedded

wizard or anathor software for designer

. I would like to learn to make small interfaces TFT displays as STM32F429i

-Discovery.

Thank you.

If you you asking me then no, I don't, sorry.
