INTERFACE EXTERNAL 2MB FLASH WITH SPI

[vohra alihussain]

I am working on nrf52832 and sdk11. I want to store my accelerometer and gyroscope data into external memory.Does anyone have code of it? or any one having .c and .h file.

I am using winbond W25Q16JV memory ic.

Any kind of help will be appreciable...

Have you looked at the SDK for the SPI driver & examples?

None of that has anything to do with Nordic or the nRF52832.

The memory chip neither knows nor cares what microcontroller you use - it just behaves as described in its datasheet.

So you need to study the memory documentation, and do what it tells you.

i read the documentation...

i am able to read jedec id and able to write and read data, but problem is i can read data where i haven't write anything. means it is writting automatically.

more likely, your addressing is wrong.
