Hello

I am trying to make a project with different sw layers (app(eg. main.c), components(eg. lvgl, ssd1963..etc) , mcal(eg. I2C, UART..etc), driver(mcu vendor I2C)). each layers has its own modules(.h .c). But the main.c is programmed by the esp-idf to only see the components folder and other ...

I found the problem.
it was the CMakeList.txt

It should contain all the .h/.c files that should be built within the main.c

the Cmakelists.txt was modified to the following:


# Edit following two lines to set component requirements (see docs)
set(COMPONENT_REQUIRES )
set(COMPONENT_PRIV_REQUIRES ...

I am trying to make LCD project based on i2s driver then I faced a problem that the functions are undefined. Then I made a simple main.c file and a another .h/.c files that contain a sum functions and still tells me the function is undefined.

main.c code:


#include <stdio.h>
#include "freertos ...

I am trying to use this solution as well as and I am facing problems due to its lack of information. So thank you for your information.

Please if you can answer some questions considering this solution:
1- What is the FPS achieved while changing the entire screen image?
2- do you have to keep ...

I am making a project of LCD interface using 480x272, 16bit-RGB LCD + LVGL library + RGB peripheral inside ESP32-S3

from my calculations:
1- 480x272= 130.56 KB --> x2 (because of 16bit-RGB) = 261.120 KB

So from this calculations I can choose a 2MB PSRAM ESP32-S3.

Is this calculations correct or ...

which are produced in mass production for the following esp32 versions:
1- esp32 WROOM / WROVER
2- esp32-s2 WROOM / WROVER
3- ESP32-s3 WROOM
4- ESP32-c3 WROOM

Thanks in advance

I am working on an LCD project interfacing ESP32 Wroom with ER-TFTM043-7S (800x480 - SSD1963) buydisplay LCD.

However I have some questions about the behavior of the I2S:

from other forums I knew that the I2S swaps the order like this

internal data : 0 1 2 3
How I2S sends it: 2 3 0 2

and then ...

I am trying to make an LCD application (buy display 480x272 with ssd1963 controller) using ESP32 WROOM. and I am trying to use Qt library for it:
But the tutorials are not very clear and I don't know where to start from.

can you please show me a way to get started with this solution
