I2C example with NRF51822

[ABDELLI-W]

Are there any I2C examples for the nRF51822 ( write/ read functions) ? If not, can anyone suggest a good starting point for I2C? I am using Eclipse kepler for development. Thank you for all suggests.

This won't work with Softdevices enabled - will it?

@clovett ,

i was seeing your wrapper you used twi_master_transfer both for reading and writing i2c data.

dont we need to use nrf_drv_twi_tx and nrf_drv_twi_rx as well ?

And what will be the twi initialization in this case ? tnx

My code is assuming the SoftDevice is available, so you must have called twi_master_init already, then my helper functions can work from there using twi_master_transfer. A read is also a "transfer" because you have to write the register address that you want to read from.

[Chris Lovett]

Ok, you are right, it looks like my code is using an older version of the Nordic sdk. The new examples that are bundled with Keil C use nrf_drv_twi_init and nrf_drv_twi_tx.

copy these files (.c,.h) to near Project main.c file and after that import to your project in Keil.
