[SOLVED] How to configure PIC16F as I2C Slave

[ProminentRD]

I'm on a project with dspic30f as Master and pic16f1705 as slave. The master is not receiving Acknowledgement from slave. I configured Master myself and used 'MCC' for generating Salve's code. Master is sending clock and data, however the the acknowledgement bit stays high. I have uploaded both the codes. Please help if someone knows to solve the problem

I'd check correct I2C unit configuration and reaction to incomming I2C communication on the slave side with in-circuit debugger.

Thanks bro, did the same and I figured it out. It was a simple address mismatch. The MCC generated code shifted a bit to left side (<<1). I just removed that.
In the datasheet it was said that the LSB was neglected so had to do it accordingly

Yes, one of the most popular faults in I2C setup. Good that you managed it.
