Hello everyone .
I tried to use dspic30f3012 with i2c on ccs program and all's right.
Now I'm trying to use the dspic with i2c on Mplabx.
I used the mplabx with xc16 and this is the code :
without closing or interrupt or ack from i2c , I don't need ack I want only to see the output on oscilloscope. but nothing !
Please help!
