After creating the partitions.csv file now let us create a folder named ‘spiffs_data‘ and inside that folder create a text file named ‘data.txt.’ This is the file that we will read from the SPI flash memory. You can add any text in this file. For example purposes, we will add ...
将闪存矢量用于ESP32 / ESP8266 EEPROM 是指在ESP32和ESP8266芯片上使用闪存矢量作为电可擦可编程只读存储器(EEPROM)的替代方案。EEPROM是一种非易失性存储器,它可以在断电后保持数据,因此非常适合存储设备配置和其他需要长期保存的数据。 在ESP32和ESP8266芯片上,通常使用Flash文件系统(SPIFFS)来存储文件和数据。然...
