What is SPI flash file system?

Spiffs is a file system intended for SPI NOR flash devices on embedded targets. Spiffs is designed with following characteristics in mind: Small (embedded) targets, sparse RAM without heap. Only big areas of data (blocks) can be erased. An erase will reset all bits in block to ones.

How does SPI memory work?

Flash memory comes built into solid-state chips, and each chip houses an array of flash memory cells. Rather than use the traditional electromechanical method, flash memory uses electrical circuits to log data. Current flows through the transistor between each cell’s source (electric input) and drain (electric output).

What is SPI NAND flash?

GENERAL DESCRIPTION. SPI (Serial Peripheral Interface) NAND Flash provides an ultra cost-effective while high density non-volatile memory storage solution for embedded systems, based on an industry-standard NAND Flash memory core.

What is Quad SPI Flash memory?

Quad-SPI, also known as QSPI, is a peripheral that can be found in most modern microcontrollers. It has been specifically designed for talking to flash chips that support this interface. It is especially useful in applications that involve a lot of memory-intensive data like multimedia and on-chip memory is not enough.

How do I upload an HTML file to Nodemcu?

Uploading Code and Files

1. Go to Sketch > Show Sketch folder, and create a folder called data. Save the HTML and CSS files inside that folder;
2. In Tools > Board, select the ESP8266 board you’re using;
3. Then, go to Tools > Flash size and select 4M (1M SPIFFS).

What is a quad SPI?

Quad SPI is similar to dual, but improves the throughput four times. Two additional data lines are added, and there are 4 bits transferred every clock cycle. The data lines are now IO0, IO1, IO2, and IO3. Quad SPI Serial throughput rates reach around 40 Mbps.

What is the difference between Qspi and SPI?

The QSPI is a controller extension for the SPI Bus. The difference is that it uses a data queue with programmable queue pointers that allow the data transfers without the CPU intervention it also has a wrap-around mode that allows continuous transfers and from the queue with no CPU intervention.
