i want to interface W25Q128FV with psoc 5lp for my GLCD project and i want to store my image files on flash ic
i found this http://www.cypress.com/documentation/code-examples/interfacing-quad-spi-memory-psoc-r-5lp
i want to check does all the register values which are used in Quad_SPIM_1_Quad_SPIM.h are compatible with my flash ic or not?
how can i check that? i tried to compare it with the datasheet but i got confused
any other options available for interfacing?

The Quad SPIM Component was designed specifically for Cypress Quad SPI Memories. Your flash IC W25Q128FV can implement the Quad SPI interface and since this a standard interface, you should be able to interface it. For understanding how the memory addressing is implemented, you can check out how Cypress implements the Common Flash Interface (CFI) at this link: http://www.cypress.com/file/195291/download
