what's the difference between spi_w5_master and nrf_drv_spi on SDK10

[makouda]

with SDK 10 I found 2 SPI libraries, spi_w5_master and nrf_driv_spi. I hesitate between them. what' the difference between them? and what should I use when I'm using app_timer???

The spi_w5_master driver is a 5-Wire SPI driver, i.e it uses an additional data line for flow control.

The nrf_drv_spi driver is the standard 4-Wire SPI driver and I recommend using this as this driver is better documented, see this page on our Infocenter.
