kandi X-RAY | SPIFlash Summary

SPIFlash is a C++ library typically used in Internet of Things (IoT), Arduino applications. SPIFlash has no bugs, it has no vulnerabilities, it has a Strong Copyleft License and it has low support. You can download it from GitHub.

[license] Arduino/Moteino library for read/write access to SPI flash memory chips. This works with 256byte/page SPI flash memory such as the [4MBIT W25X40CLSNIG] used on [Moteino] for data storage and wireless programming. For instance a 4MBit (512Kbyte) flash chip will have 2048 pages: 256*2048 = 524288 bytes (512Kbytes). Minimal modifications should allow chips that have different page size to work. DEPENDS ON: Arduino native SPI library. This library was primarily developed to enable safe wireless programming on Moteino nodes and Moteino based applications such as the [SwitchMote] This has been documented at [lowpowerlab] [Dualoptiboot] (all AVR based Moteinos come with it) and [RFM69_OTA WirelessProgramming library] are required to be able to wirelessly re-flash a remote Moteino.

How to store data in flash memory of ESP32?

QUESTION

How to store data in flash memory of ESP32?

Asked 2020-Dec-17 at 06:16

I am trying to use this library to store data into the ESP32 flash memory. I am particularly using this example to write and read float values. I have just added a Serial.println("error") to this code as follows -

Some ESP32's have integrated flash memory. Some use an external flash chip. This flash holds the application firmware, may have a filesystem on it (usually SPIFFS) and may have a key value store (NVS). This flash is the primary, and usually only, flash memory on an ESP32.

The library you're trying to use cannot work properly with the primary flash memory I described above. The library you're trying to use would require a secondary flash chip to be connected to the ESP32. If it did use the primary flash memory it would take control of it and interfere with the ESP32's ability to run its firmware. Only use this library if you're connected secondary flash to the ESP32.

To use the flash storage that comes with the ESP32, either use SPIFFS for a filesystem or use Preferences (NVS) for a key value store. Both are part of the Arduino Core for the ESP32, are easy to use and don't require a second SPI flash chip.
