PIC microcontroller i2c slave mode receiving data problem [Copy link]

I am using pic18f26k83, and i2c is in slave mode. When receiving data, it can recognize the address and give ack. However, when receiving data, it cannot trigger the WRIF interrupt or the RXIF interrupt, and it cannot enter the interrupt function to process the data. The register configuration should be fine. Since the relevant code is in the internal computer, I can only upload it with photos. Please give me some advice! Thank you very much!

1) The photos you took are not clear. You can check them yourself after writing the post. If you can't see them clearly, how can others? 2) It is best to check the interrupt configuration carefully according to the specification.

Thank you for taking the time. The mobile browser I used to post does not support browsing the pictures before posting. It is indeed not clear. I will go back to the computer tonight to try to post. I am also a beginner. According to the device manual and the code compiled by the mcc library function, there may be some problems that I cannot find at my current level, so I would like to trouble you all.
