First guide shows how tosave data permanentlyon the ESP32 flash memory using thePreferences.hlibrary. The data held in the flash memory persists across resets or power failures. Using thePreferences.hlibrary is useful to save data like network credentials, API keys, threshold values, or even th...

开发板管理器中,搜索esp32,安装2.0.13版本(需要安装2.0.16之前版本,不然不匹配tft_eSPI库,程序会重启)。 img 2. 安装tft_eSPI库 2.1. 驱动库安装 库管理中,搜索tft_eSPI,安装最新版本2.5.43。 img 2.2. 库代码修改 这里需要修改引脚代码,适配st7789驱动。
I have 4kb (it's a structure) of data that needs to be stored permanently and sometimes updated (not all together but some structure variables as needed). Currently I have created a spiffs partition where I will overwrite a file with all this data whenever there is a variation. However, ...
