GETTING STARTED WITH PICKIT SERIAL ANALYZER

Figure 1-1 shows the MCP4728 Evaluation Board, and Figure 1-2 shows the

connection of the MCP4728 Evaluation Board and PICkit Serial Analyzer.

The following steps describe how to use them together:

Connect the MCP4728 Evaluation Board’s 6-pin socket to the PICkit Serial

Analyzer as shown in Figure 1-2.

Connect the oscilloscope probes to the SCL and SDA test terminals (optional).

Connect a multimeter to one of the DAC’s output test terminal.

VDD Selection: You can use the VDD from the PICkit Serial Analyzer or use your

own external VDD. The JP1 connector selects the VDD path.

(a) Connect JP1, if using VDD from PICkit Serial Analyzer,

(b) Disconnect JP1 and apply VDD at VDD1 pin, if you are using an external VDD.

• I2C device code of MCP4728: ‘1100’

• A2, A1, A0 Address Bits: Pre-programmed to‘000’.

Connecting VDD: LED D1 turns on when VDD is applied. The PICkit Serial

Analyzer will provide VDD automatically, if it is connected to the PC. Make sure

LED D1 turns on.

Use the PICkit Serial Analyzer PC GUI to send I2C write and read commands.
