2 BOOST-DAC8730-HART Hardware Setup
This section provides the overall system setup for the BOOST-DAC8730-HART Booster Pack. The
Booster Pack can be evaluated standalone – with any SPI- or UART-capable microcontroller – or with the
MSP430FR5969 LaunchPad™. The software provides installation steps to install the necessary
LaunchPad drivers, and MSP430FR5969 firmware. Additionally, the Graphical User Interface (GUI)
provides an interactive interface that syncs communication between the MSP430FR5969 LaunchPad and
DAC8730 device. The hardware (BOOST-DAC8730-HART and MSP430FR5969LP) is powered externally
via the loop connections of the BOOST-DAC8730-HART J2 terminal block. Figure 1 displays the system
setup for the BOOST-DAC8730-HART.
Figure 1. BOOST-DAC8730-HART Hardware Setup
2.1 Theory of Operation for BOOST-DAC8730-HART Hardware
A block diagram of the BOOST-DAC8730-HART board is displayed in Figure 2. The board provides an
external terminal block (J2) for the supplies, and a digital header connection (J1) that enables connection
to the DAC8730 digital pins. Once powered, the DAC8730 outputs a voltage that powers the
MSP430FR5969 LaunchPad. The BOOST-DAC8730-HART includes a diode bridge and protection circuit
that is tied to the J2 terminal block. This protection allows any polarity of power into the J2 terminal block.

4.3 BOOST-DAC8730-HART Power Configurations
The BOOST-DAC8730-HART provides a terminal block (J2) to connect to the external loop-supply. A
typical two-wire connection has a sense resistor tied to either the negative or positive node of the external
supply. A minimum loop resistance value of 250 ohms is commonly required for HART communication.
The minimum voltage for DAC8730 device operation and other parameter requirements are listed in the
DAC8730 data sheet (SLASEH8). For correct loop operation, please be aware that the loop-supply
voltage must exceed the sum of both the minimum voltage requirement of the DAC8730 device, and the
IR drop across the sense resistor.

5 BOOST-DAC8730-HART Software Overview
This section discusses how to use the BOOST-DAC8730-HART software.
5.1 Starting the BOOST-DAC8730-HART Software
Once the hardware connections are established and jumper settings configured, power on the BOOST-
DAC8730-HART with the loop-supply voltage. Next, launch the software located in the Texas Instruments
folder of the Start All Programs menu, and select the BOOST-DAC8730-HART icon.
Figure 8. BOOST-DAC8730-HART GUI Location
If the LaunchPad is properly connected to the BOOST-DAC8730-HART, the GUI should automatically
display "HARDWARE CONNECTED" on the lower left of the GUI, as seen in Figure 9.
Figure 9. BOOST-DAC8730-HART GUI – Power On
If the LaunchPad has a faulty connection, or is not connected at all, the GUI will launch in DEMO mode. If
this text appears while the LaunchPad device is connected, then power off the loop-supply voltage, unplug
the LaunchPad, and close the GUI. Reconnect the LaunchPad and ensure that the connectors are
correctly aligned. After this, verify the USB extender cable is properly connected to both the LaunchPad
and PC. Reapply the loop-supply voltage and re-launch the GUI. This issue can also occur if the MSP430
driver is installed incorrectly, and so the BOOST-DAC8730-HART software may need to be reinstalled.
5.2 BOOST-DAC8730-HART Software Features
The following subsections describe the functionality of each page of the BOOST-DAC8730-HART GUI.
5.2.1 BOOST-DAC8730-HART Low Level Configuration Page
The BOOST-DAC8730-HART features a Register Map page that allows access to low-level
communication by directly writing to and reading from the registers of the BOOST-DAC8730-HART.
Selecting a register on the Register Map list will present a description of the values in that register, and
also display register information such as the address, default value, size, and current value. The register
values can be modified by either writing directly to the value column or selecting the bit individually. This is
shown in Figure 10.

Figure 10. Low Level Configuration Page
The values of the register map can also be saved by pressing the Save Configuration button under the
File menu option. Additionally, the configuration files can be accessed through the Load Configuration
button.
Other options selectable by the user are the Update Mode,Write Selected (red box), Read Selected
(orange box), Write Modified (gray box) and Read All (yellow box) icons. All icons are displayed in
Figure 11.
Figure 11. Low Level Configuration Page Available Options
If Update Mode is selected to “Immediate”, all changes to register values will update immediately, while
“Deferred” allows the user to modify the value of a register without taking effect until the Write Selected, or
Write Modified icon is pressed.
The Read Selected icon allows individual register reads, while the Read All icon reads the status of all
registers located in the register map.

5.2.2 BOOST-DAC8730-HART High Level Configuration Page
The High Level Configuration page provides an interface to observe and control the different data
registers, modes, and configurations available for the BOOST-DAC8730-HART device. This page is
displayed in Figure 12.
Figure 12. High Level Configuration Page
The main page primarily has 3 functions – the PWM Exerciser, the HART Exerciser (transmit and read),
and the Device Status button.
The 16-bit PWM DAC can be exercised by writing to the MSL and LSB fields and pressing the OK button
for Set PWM – the appropriate code range is 0x1000 - 0xEFFF.
The HART interface is controlled via UART, which is controlled in the firmware of the MSP430FR5969
device. To create a transmit packet type the data, in hexadecimal format, to the HART DATA array and
press the OK button located under Start HART Transmission. The resulting HART waveform can be
captured by monitoring the differential voltage across the loop-supply pins or the shunt resistor. To clear
this array, press the OK button located under Clear HART DATA Buffer.
NOTE: The DAC8730 device creates a local ground from the loop-supply voltage. In the case that a
desktop machine is used, the USB connection will share an earth ground connection with the
local ground that is generated from the DAC8730 device. Therefore, to avoid any potential
shorting between earth ground and probed nets, the user will require a differential probe
when inspecting the HART waveform.

BOOST-DAC8730-HART Evaluation Module
The DAC8730 device notifies the microcontroller of a valid HART transaction, and will send this
information to the microcontroller, which in turn will store to a buffer. Pressing the OK button located under
READ HART reads the byte information from the buffer. This information is displayed in the Status String
indicator field in hexadecimal format.
Pressing the OK button located under Device Status will read the Status Nibble of the DAC8730 device,
which will notify of any errors or flags. This information is displayed in the Status String indicator field in
hexadecimal format and is detailed in Table 7.
