Introduction

lib_qspi_fast_read is a library for interfacing with a QSPI flash device on an XMOS device. This library achieves higher data transfer bandwidth than the default supplied flash libraries at the cost of flexiblity and write/erase functions.

The SCLK is derived from the system clock, so maximum data rates can only be achieved on the XMOS XS3 architecture.

See Getting Started to begin with an XMOS development board.

See Hardware Selection for flash part parameters to check for designing your own board.
