CREATING A SYSTEM WITH A PIC12F1572 MICROCONTROLLER AND A
MCP48FEB22 DAC

The following image illustrates how to connect two ADM00309 boards in order to obtain
a functional system. One board hosts a PIC12Fxxxx, which is programmed using a
PicKIT3 connected to J1, and controls a second board, which has a
MCP48FEB22-E/UN device installed. The J2 connector of the PIC board is used as a
serial communication port, being connected to J1 of the DAC board.
