Refer to change log for further information about this release. The programming procedures can be observed through the serial monitor of Arduino IDE. Learn everything you need to know in this tutorial. The SPI Flash is connected to 4 pins that are not brought out on the GPIO pads. The maximal throughput is up to 10,000,000 bits/s and much faster than I2C and UART. Assuming you don't plan to use the chip in anything but standard SPI (not Dual- or QSPI), then all the signal pins are unidirectional! This way you don't have to worry about the SPI flash colliding with other devices on the main SPI connection. Other digital communication methods include the I 2 C bus and the serial UART bus. La flash SPI Il s'agit du même type de FLASH que sur un ESP8266 ou un ESP32. Familiar file-based functions, similar to the SD library, are used to access data. However, I need more SRAM on the Arduino, so I will use a SPI SRAM chip (32K256). Arduino SPI as Master The memory is organized in a multiple overlay structure which is nice for erasing but for my purposes, it's basically just 32,768 pages of 256 bytes each. That means that in the Arduino->Flash direction, a voltage divider that divides 5V down to 3.3V is sufficient (place it close to the receiving end, usually). Just updated to v 1.0.1 and added the ability to output data to Serial as CSV decimal values. A few advantages of the SPI interface are widespread adoption, signal integrity, flexibility in protocol design, and simplicity. Save the Arduino sketch as ESP8266_SPIFFS_Web_Server or download all project files here.
