1 Overview
The AFE881H1 16-bit digital-to-analog converter (DAC) is a highly-integrated, high-accuracy, and extremely low-
power device with voltage-outputs designed for HART® enabled sensor transmitter applications. The AFE881H1
includes most of the components required to construct a transmitter for 2-wire (loop-powered), 4-mA to 20-
mA sensor transmitter applications. These components include a 16-bit highly accurate DAC, a HART FSK
modem, an internal 10-ppm/°C voltage reference, and an internal diagnostic ADC. To accommodate intrinsic and
functional safety concerns, external voltage-to-current conversion and power-regulation are required.

To connect the EVM board and the USB2ANY Interface Adapter together, firmly slide the cable ends of the
30-pin ribbon cable into the USB2ANY Interface Adapter and the AFE881H1EVM, as shown in Figure 3-4. Make
sure that the connectors are completely pushed together. Loose connections between the USB2ANY and the
EVM may cause intermittent operation.

3.6 Connecting the USB Cable to the USB2ANY Interface Adapter
Figure 3-5 shows the typical response to connecting the USB2ANY Interface Adapter board to a USB port for
the first time. Typically, the PC responds with a Found New Hardware, USB Device pop-up dialog window. The
pop-up window then changes to Found New Hardware, USB Human Interface Device. This pop-up indicates that
the device is ready to be used. The USB2ANY Interface Adapter uses the human interface device drivers that
are included in the Windows® operating system (OS).
In some cases, the Add Hardware Wizard appears. If this prompt occurs, allow the system device manager to
install the human interface drivers by clicking Yes when requested to install drivers.
Figure 3-5. Confirmation of USB2ANY Driver Installation
CAUTION
The EVM default configuration does not require external power supplies, and power is sourced from
the USB2ANY. If external supplies are used, disconnect the supply connection from the 3p3V line
coming from the USB2ANY before attaching external supplies.
3.7 Optional EVM Operations
This section describes the various operational options that can be used by the EVM.
3.7.1 Power Configuration
The default configuration of the AFE881H1EVM allows the board to be powered from the 3p3V line coming from
the USB2ANY. Jumper J3 connects power from the 3p3V line to the PVDD and IOVDD pins of the device. To
use external power supplies, remove the jumpers in J3 to connect supplies to J1 and J4 for connections to
PVDD and IOVDD. When the external supply is 1.8 V, install R1 on the board; this resistor is not installed by
default. Provide the external 1.8-V supply to PVDD, VDD, and IOVDD through J1 and J4.
3.7.2 External SPI and UART Controllers
To use an external SPI or UART controller with EVM board, disconnect the USB2ANY controller, and disable the
U2 level shifter by uninstalling R13 and installing R2.

4 Software Overview
This section discusses how to use the AFE881H1EVM software.
4.1 Software Installation
Before starting software installation, verify that the USB2ANY controller is not connected or else the driver may
not properly install.
Download and run the latest version of the EVM GUI installer from the Tools and Software section of the
AFE881H1EVM web folder to install the EVM GUI software on your PC. The software installation automatically
copies the required LabVIEW™ software files and drivers to the local machine. The AFE881H1EVM installer
installs all the driver files necessary to operate the USB2ANY controller.
Choose the destination directory for the GUI software, accept the license agreements, and follow the on-screen
instructions shown in Figure 4-1 to complete the installation.
Figure 4-1. AFE881H1EVM Software Installation Prompts
To use the scripting tool, the Python™ programming environment must also be installed. Download the latest x86
version of Python 2.7 at https://www.python.org/downloads/.

4.2 Launching the Software
After installation, a shortcut to launch the GUI can be found in the Start menu. If installed in the default directory,
the AFE881H1EVM software can also be launched by navigating to the Texas Instruments folder in the Program
Files (x86) directory, as Figure 4-2 shows.
Figure 4-2. Launching the AFE881H1EVM GUI
Figure 4-3 shows the GUI after launch. If the USB2ANY controller is not connected to the PC when the software
is launched, the GUI defaults to demo mode. Figure 4-4 illustrates the bottom-left corner of the GUI showing
the hardware connection status: DEMO MODE or CONNECTED. After the USB2ANY controller is properly
connected to the PC, close and reopen the AFE881H1EVM software to detect the device.

4.3 Software Features
The AFE881H1EVM GUI allows for SPI communication with the AFE881H1 and control of the device. While
the entire register map is available to the user, some features have been integrated into user controls for easy
operation.
4.3.1 AFE881H1 Register Page
Figure 4-5 shows the AFE881H1 Register page of the AFE881H1EVM GUI. This page allows direct access
to all registers on the AFE881H1. The GUI handles page address management, allowing seamless access to
registers.
The Register Map section in the center of the page lists all the registers, grouped by the pages in the device.
Directly above the Register Map section are four buttons that allow read and write access to all registers.
The Field View section on the right side of the page shows the various fields in the currently selected register.
Select a register name to highlight the register. The Field View section displays the register contents as
described in the data sheet.

4.3.2 High Level Configuration Page
The High Level Configuration page is used to set the configuration of the AFE881H1EVM GUI. Figure 4-6 shows
the AFE881H1 High Level tab of the High Level Configuration Page. This tab is used to set the DAC range and
outputs, ADCs controls and settings, and HART modem functions for the device. Alarms and status information
are also displayed on this tab.
Figure 4-6. AFE881H1 High Level Tab
4.3.3 Using the Python Scripting Tool
The AFE881H1EVM software provides a scripting tool to automate register reads and writes for reuse. To use
the scripting tool, the Python™ programming environment must be installed. Download the latest x86 version of
Python 2.7 at https://www.python.org/downloads/. To launch the scripting tool, click Script > Launch Window, as
shown in Figure 4-7.

The scripting tool launches a Python IDLE window. This window lists any register interaction when recording a
macro. To record a macro, find the Launch Window function in the Scripting tab. Figure 4-8 shows the scripting
tool recording a macro. After the actions are recorded, use the Stop button to end the script. This script can be
saved and reused as desired.
Figure 4-8. Scripting Tool Recording a Macro
If the python IDLE window does not appear, check the settings for application execution aliases. To do so, open
the Windows Settings, and then select Apps. In the resulting Apps window, select Apps & features, and then
click on the Manage app execution aliases link. The next page loads a list of apps. Deselect both application
installers for python.exe and python3.exe. Figure 4-9 shows the windows settings for managing application
execution aliases.
