How to wire I2C for NRF 51822 with MPU 9250.What SDK should I use?

[priya]

nRF5_SDK_11.0.0_89a8197 - with MPU.7zthis is how my nRF go studio looks with example blinky and works well. nRF5_SDK_11.0.0_89a8197 - Copy.7zI am trying to wire NRF 51822 over I2C with MPU 9250. If I should use the GPIO's where should I initialize the Pins . What SDK should I use?

Hi,

You can use any free/available GPIO pin you have on your board. All GPIO pins can be individually mapped to interface blocks for layout flexibility.

I would recommend using the newest SDK version that supports the nRF51 series, which is SDK 12.3

I would also recommend taking a look at the MPU examples found here.
