how can i do i2c initialization on any gpio pin in nRF52810?

[Urvisha Andani]

Hello all,

I am right now working on one project. where i use BT832 in which nrf52810 BLE ic use. i use segger studio in windows 7. For reference i use nRF 5.2.0 SDK. right now i am doing i2c communication of temperature sensor(lm6bd) with ble board. but can you please tell me how can i use any gpio pin as i2c (SDA and SCL ) pins ? i am trying to do same using pin P0.06(SDA) and P0.07(SCL). so is this possible that i can read data of temperature sensor from pin which i mention.

I have read data for same at pin P0.27(SCL) and P0.26(SDA). and i successfully got result and i want get same data from different pin. because my project has requirement to use i2c at a different pin. And also i have read data for same at pin P0.31 and pin P0.30. and i successfully got result.

So please guide me how can i do? what should i need to change in program for configuration i2c at gpio pin.

Thanking you,

you can simply just change the pins like shown below

Just change .scl and .sda the twi_config variable declaration.

I have used EXT_SDA and EXT_SCL which are defined above.

No other changes should be required.
