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.

The accelerometervalues can be found in accel_values. There is a timer that sets the start_accel_update_flag to true every 1 second. When the flag is set to true, the accelerometer values are read using the function mpu_read_accel(). If you want to send/get the values more often, you can reduce the value of TIMER_INTERVAL_ACCEL_UPDATE.

What do you mean by "three arrows" ?
