not sure what converter you are using to convert the ttl tors232, either a max232 chip or if that is all included in the demo board so you just have to connect the computer to it. However i can probab ...

yes i do realize, and i see a blurp where the master tries to send an ack, but then i hold the scl low so the master cant send a stop.

I tried adding the following in hopes to try and force the sl ...

Thanks. If the master does not send an ack after receiving the data i send it. would that cause the pic to hold the SCL line low?

Thanks. I am thinking I am going to have to wait until I get their test box to fully explore this. Just for clarification of how this is working though.

If they are sending to slave address 0x33, I ...

I got 2 PIC16F886 communicating with each other. However, if I make the slave address odd, it doesn't work.

In the slave file I have

#use i2c(slave, slow, force_hw, sda=PIN_C4, scl=PIN_C3, ...

Thank you all for reading and responding with what you did. Got it working now. In all my testing i never got things sorted out just right. In the master program i need to do a i2c_read(0) command, wh ...

I want chip A to send a byte that is a question, ie if chip B receives 0xFA from chip A, chip B will respond with 0x32. It is for status verification and monitoring. For this code though I just want c ...

I am using a pic16f886 and can use some help. I have read extensivly the posts about this subject and nothing seems to work. I am trying to do i2c communication between 2 pics.

Code is listed below ...
