spi flash相当于spi从机，当要读取数据的时候，就发数据过去，同时接收数据
A nonvolatile memory device, in a continuous read operation, requires no dummy bytes between receipt of a read command and commencement of a scanning out of a first target data byte. The highest order bits of a range of possible target data bytes are speculatively read while only a partial ...
A nonvolatile memory device (300; 3), in a continuous read operation ( 5), requires no dummy bytes between receipt of a read command (505) and commencement of a scanning out of a first target data byte. The highest order bits of a range of possible target data bytes are speculatively ...

The FlashStorage_STM32 library, inspired byCristian Maglie's FlashStorage, provides a convenient way to store and retrieve user's data using emulated-EEPROM, from the non-volatile flash memory of STM32F/L/H/G/WB/MP1. The flash memory, generally used to store the firmware code, can also...

The FlashStorage_STM32 library aims to provide a convenient way to store and retrieve user's data using the non-volatile flash memory of STM32F/L/H/G/WB/MP1. It's using the buffered read and write to minimize the access to Flash. It now supports writing
