Upon startup, the DAC is set to the last value stored in
the MOTP register. To modify the DAC output or the
MOTP register setting, click on the DAC or MOTP radio
button, respectively, in the Register group box and
perform one of the following in the VCOM group box:
1) Move the scrollbar, or
2) Type a register value directly into the Reg Value
edit box (7-bit decimal equivalent), or
3) Type in the desired output voltage in the Output (V)
edit box. The software uses a register value that
generates a voltage closest to the desired voltage
value.
Press the Write button to update the MAX9660 IC with
the entered register value. Data written to the DAC is
volatile. Data can be written 30x to the nonvolatile
MOTP register. The factory-default MOTP register set-
ting is 64.
The Options menu item provides access to an
advanced 2-wire interface and demo mode. The Help
menu item provides help and general information about
the EV kit software. The File menu item provides the
option to exit the EV kit software.
VCOM Voltage Calculation
The VCOM voltage is calculated using an on-board
resistor-divider (R14 and R15), a resistor (R13) that sets
the full-scale sink current, AVDD voltage, and the deci-
mal DAC code (CODE) as follows:
? R 15 ? ? ? CODE + 1 ? ? R 14 ? ?
128
where CODE ranges from 0 to 127.
The VCOM voltage can be measured across the
VCOMOUT and GND PCB pads.
Advanced User Interface
A serial interface can be used by advanced users by
selecting Options | Interface (Advanced Users) from
the menu bar.
Click on the 2-wire interface tab shown in Figure 2.
Press the Hunt for active listeners button and select the
MAX9660 slave address 0x9E from the Target Device
Address: combo box. In the General commands tab
sheet, select the S - SMBusSendByte(addr,cmd) item
in the drop-down list. Enter the desired hexadecimal
data values into the Command byte: combo box and
press the Execute button.
