WebThe spi_flash component contains APIs related to reading, writing, erasing, memory mapping data in the external SPI flash. It also has higher-level APIs which work with partitions defined in the partition table. Note that all the functionality is limited to the “main” SPI flash chip, the same SPI flash chip from which program runs. WebSPI is the “Serial Peripheral Interface”, widely used with embedded systems because it is a simple and efficient interface: basically a multiplexed shift register. Its three signal wires hold a clock (SCK, often in the range of 1-20 MHz), a “Master Out, Slave In” (MOSI) data line, and a “Master In, Slave Out” (MISO) data line.
