My suggstion is to use the 'hal_w2.c' (IIC compatible) library from nRFgo SDK v2.3. You can find example usage of the library in the 'display_joystick_example'. This library contain a workaround for a deadlock condition that may occur on the interface if there is a NACK condition. In specific check out hal_w2_soft_reset() in hal_w2_read().

after i use interrupt for IIC communication,SCL level sometime is correct,sometimes it is low,and then it cannot communication.

the details is as below:

when reading data from EEPROM,the first times communication is well,and then the communication is halted because it cannot trigger 2 wire transmitted/received interrupt,and SCL level is low. in other words,it cannot realize Continuous reading communication.

writing operation goes well after using delay function.

please give me some advise,thank you very much.

Hi, can you show with a screenshot what timing is problematic?
