ESP Terminal with 3.5inch SPI Capacitive Touch Display and Camera

Timo · July 2023

Hi,

i have issue to use the examples from this site or the lessons.

https://www.elecrow.com/wiki/index.php?title=ESP_Terminal_with_3.5inch_SPI_Capacitive_Touch_Display

The first one A-LCD will work.

A-CAMERA not. Arduino shows in the serial monitor:

E (1113) cam_hal: cam_dma_config(300): frame buffer malloc failed
E (1113) cam_hal: cam_config(384): cam_dma_config failed
E (1113) camera: Camera config failed with error 0xffffffff
Camera init failed with error 0xffffffff

At the lessons i tried the some and i have a loot of errors with lv_examples.h and lv_demos.h.

I installed the newest version of "lv examples" via the library manager, but the lessons will not work.

i also copied the lv_conf.h file in the root dir of the library.

What can i do to use the examples or lessons?

Kind regard from Germany,

Timo

@Timo Hello,

May I ask what version of the esp32 package you installed? Is it 2.0.3?

Before you download the program to the terminal, you need to press and hold the boot button, and then press the reset button to make the terminal enter the burning mode.

In addition, please check whether the configuration of the board is consistent with what is written in the wiki.
