Cannot find "SDMMC_HOST_DEFAULT"

Postby chikichaka » Thu Dec 15, 2022 1:23 am

I'm trying to use SD CARD in my project.

When I tested example project of SD CARD, it is totally fine.

However, I failed to compile with thoese erros.

I also included thoes files
#include "esp_vfs_fat.h"
#include "sdmmc_cmd.h"
#include "driver/sdmmc_host.h"

ESP-IDF: v4.4.3

Code: Select all

Which chip are you compiling the project for?
