Winbond SPI external Flash Memory W25qXX

The_user_23

I am trying to store my temp sensor readings in an external flash memory( Winbond W25qXX ).

Can you provide me the respective driver for the same?

BTW I have found driver for STM32 and i tried to modified that but I am getting errors in following functions:

    Hi

    Normally the implicit declaration error means that you are trying to call functions that you haven't implemented anywhere. 

    This makes sense, as the low level HAL functions will need to be re-implemented on the nRF device since they will look completely different to those from the STM libraries. 

    Essentially you have two options:

    1) Implement the HAL_SPI functions in a similar way to how they work in the STM libraries, but accessing Nordic hardware instead. 

    2) Change the higher level driver to use nrfx SPI functions instead of the STM HAL functions. Basically you have to find every reference to these functions in the code and replace them with nrfx counterparts. 

    Best regards
