https://devzone.nordicsemi.com/f/nordic-q-a/45137/twi-callback-function-can-t-build-dynamicallyHello All. I try to build a generic function that read device reg over its I2C. I take the TWI master example of Nordic. There is need for callback function to get in the ISR whenever there is a replay. It build statically put the function nameen-USTelligent Community 13Thu, 21 Mar 2019 13:31:56 GMThttps://devzone.nordicsemi.com/thread/177592?ContentTypeID=1Thu, 21 Mar 2019 13:31:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f35cbcaf-f6c6-44be-b1aa-4110a0413609Einar Thorsrud<p>I see. Let us know if you still have problems.</p> <p>Also, I want to mention that the SDK includes a library for accessing arbitrary I2C registers: the nrf_wi_sensor library (&lt;SDK&gt;\components\libraries\twi_sensor\nrf_twi_sensor.h). It is not used by any of the TWI examples in the SDK. However, you can see how it is used in many of the drivers under &lt;SDK&gt;\components\drivers_ext\.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/177328?ContentTypeID=1Wed, 20 Mar 2019 12:43:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:40bbd648-82af-4630-b5ed-97739bf6b4f5Bar<p>My mistake.
