yes, I am replacing the Atmel functions with Nordic functions in their wrapper source code. I will report when I make it done.

I don't know how atmel libraries look like, but maybe you could just dig up their library for functions that are responsible for SPI transmission/reception, and just switch them to ones that nordic provides? maybe you will need some refactoring, but that should be possible...

As Atmel also provides examples on their MCU to control the Atmel wifi module WINC1500, I thought to reuse them on nRF52832, that's why I made effort the port the Atmel codes onto nRF52832.

Thanks. I have run the spi master example. With the code I can transmit data to the winc1500, and can see the data ("nordic") on oscilloscope. Can I say that, if the jumpers are connected correctly, the spi transmission is successful?

Please download nordic SDK (version 11 is newest), and open \nRF5_SDK_11.0.0_89a8197\examples\peripheral\spi (if you use new nRF52-DK, PCA10040 is for You) and familiarize yourself with SPI driver. I think you don't need file you are asking about, at all...

Hi Wojtek, thanks for your reply. according to an example, where people port the Atmel winc1500 codes to the STM mcu. I notice that the ported main.c function has a header "stm32f4xx_hal.h", which includes the common configurations for the whole HAL library on STM mcu. I would like to know, as to nrf52832, which header of such kind should I include, is it "app_util_platform.h"? thanks!

You can start by checking SPI examples available in SDK - it should give you better overview how spi on nrf5x works... Then you could maybe specify your question somehow better

Hi Wojtek, I am facing the similar task, to enable SPI communication between nordic nrf52832 and a wifi chip (winc1500) from atmel, should I do anything on the SPI slave side? I have example of SPI communication of Atmel, but have no idea how to port. Could you give me some suggestions?

Why do You want to use SPI slave also? SPI master is all you need in this case.
