How to assign a pin to SPI

[yillkid]

Hi all

1. According nRF51822 Product Specification, GPIO pin can config to SPI interface. Means if I set a specific GOP pin range to SPI and connect these pins with a oscilloscope, at least I can see the signal from SCLK if I want to test it works or not right ?

2. How I start to do that? any good example on examples of SDK ?

Hi

You could try the attached example. It is an alternative driver to the one in the SDK, and makes it very simple to change the GPIO configuration.

Just copy the main folder into your boards\nrf6310 folder in the SDK and it should compile.
