Getting started with the graphical user interface for the STEVAL-IME014V1B evaluation kit
Introduction
The graphical user interface for the STEVAL-IME014V1B evaluation kit helps to configure the STHV1600 16-channel high voltage pulser for ultrasound imaging applications and build custom waveforms to test the device.
The GUI allows setting up environment variables like clock and pulse frequencies, as well as waveform operating modes.

1.2
Note:
How to run the GUI
This software is designed and tested for Windows 7 and 10, and requires Microsoft .NET Framework 4.0 to run.
The minimum screen resolution is 1024 x 768.
Download the GUI
The GUI is available for download from the following location on the ST website: STEVAL-IME014V1 product page
How to connect STEVAL-IME014V1B to your PC
Step 1.
Connect a type A to mini type B USB cable between the USB connector on the STEVAL-IME014V1 board and a USB port on your PC
Use the USB connector on the STEVAL-IME014V1 board, instead of the one on the Nucleo board.
USB connection is also suitable to provide low voltage supply to the board, while connected.
Figure 2. USB connection
Step 2.
A removable disk appears in the Computer Resources.
The name of the disk is ST_IME014V1, with a capacity of 10 KB.
Figure 3. ST_IME014V1 disk drive
1.3
1.
If the USB device is not recognized, try a USB + charging port with the symbol.
2.
If this doesn’t work, provide suitable VEXT (pin 4) power supply and GND (pin 5) on the STEVAL-
IME014V1D power supply module before connecting the USB cable.
Run the GUI
After running the STSW-IME014_V1_1_1.exe file, the STSW-IME014GUI main window opens.

How to configure the board with the GUI
Set the environment parameters
The environment parameters available on the GUI window are:
• [f
CLKSYS
] allows you to select one of the available CLKSYS frequencies for the STHV1600:
– 10 MHz
– 50 MHz
– 100 MHz
– 200 MHz
The system may not function properly at 200 MHz because the STEVAL-IME014V1B uses a CMOS interface to provide system clock to the STHV1600 device, whereas a differential interface is usually recommended for high frequencies.
• [ Operation mode ] selects how the waveform is driven:
– Single: one trigger event is generated whenever [ PB1 ] is pressed. On XDCRs, the waveform is generated only once.
– Continuous: after [ PB1 ] is pressed, a trigger event is generated according to desired Pulse Repetition
Frequency set via the [ Rep time ] box. On XDCRs, waveforms are repeated until [ PB1 ] is pressed again.
– CW: waveforms are continuously generated (no pauses) according to [ PB1 ] (used for Start and Stop).

Set the environment parameters
Note:
• [ Rep time ] box (Continuous mode only): is the time between the rising edge of a trigger and the next one; that is, the time between two consecutive TX phases.
The trigger signal generated by STEVAL-IME014V1B is defined as follows:
• State 0: the trigger is set to a low logic level for 500 ns. This interval cannot be modified by the user.
This limit for State 0 of trigger signal applies only to the STEVAL-IME014V1B evaluation kit. The actual trigger to
STHV1600 can be different on the user's application.
• State 1: equals the value in the [ Rep time ] box minus 500 ns

Enable and disable channels
Enable and disable channels
Every channel on the STHV1600 16-channel high voltage pulser can be enabled in TX or in RX.
If a [ TX ] or [ RX ] box is checked for a given [ CHxx ], that channel is enabled in TX or RX, respectively; if neither is checked, the channel is disabled.
Each channel [ CHxx ] can be enabled for both TX and RX.
The [ Select All ] and [ Deselect All ] boxes allow controlling the channels collectively.

PW waveform management
Follow the procedure below to create and edit PW waveforms.
Step 1.
Ensure the selected [ Operation mode ] box is [ Single ] or [ Continuous ].
Step 2.
Click the [ Waveform SET ] button.
The Waveform management window opens.

PW waveform management
Step 3.
Select the [ WF x ] tab to view or edit, or click the [ + ] tab to create a new waveform
It is possible to build up to 100 waveforms.

Step 4.
Use the state drop-down menu to set a functional state and insert the desired duration in the "State duration" box.

PW waveform management
Note:
Step 5.
Push one of the five buttons to perform the following operations: a.
[ Add state ] button: adds a new state to the waveform. Normally it adds the state described in the state panel (above the five buttons) at the end of waveform, but if a state is selected in the view panel (list of states shown on the left of the five buttons), it is possible to add the new state before or after the selected state.
b.
[ Remove selected state ] button: removes any selected states of the view panel.
c.
[ Update selected state ] button: substitutes the state selected in the view panel with the new parameters in the state panel.
d.
[ Add a repetition of selected states ] button: repeats two or more consecutive states selected in the view panel, for the number of specified iterations.
Although the STHV1600 device allows compacting repetitions, the GUI does not allow saving RAM space into the STHV1600 waveform memory as it occupies more STHV1600 memory, directly proportional to the number of repetitions.
e.
[ Delete waveform ] button: deletes the entire waveform.
Figure 11. Waveform build panel
Step 6.
Use the waveform view panel to view the individual states of a selected waveform.
Use this panel to select a single state or a group of states .For new/empty waveforms, "END waveform" is the only state listed in the view panel.

Step 1.
On the GUI, click the [ Generate .txt & .bin programming files for STEVAL-IME014V1B ] button.
The software will prompt giving the option of programming the STEVAL-IME014V1B board with the new file.

Step 2.
Click [ Yes ] to generate the config file and program the device.
[ No ] generates the config file only.
A popup window appears with instructions to connect the board and save the bin configuration file to the appropriate location.
Step 3.
Ensure the USB port on the board is connected via cable to your PC.
Step 4.
Click the [ OK ] button.
The Save the STEVAL-IME014 configuration binary file window appears
Step 5.
Select the root folder of the Mass Storage Device corresponding to the STEVAL-IME014V1B
(ST_IME014V1 drive) and enter an appropriate file name.
The previous file will be deleted.
Step 6.
Click [ Save ]
A popup window will prompt you whether you want to save the text and bin configuration files.
Step 7.
Click [ Yes ] to save the files in both formats.
They can be useful because:
– txt file lists all the registers set
– bin file can be saved and reused
One popup will appear to prompt you for the txt file name, and another will appear to prompt you for the bin file name.

How to start TX activity and overwrite default board waveforms
How to start TX activity and overwrite default board waveforms
Once the previous steps are completed, a .bin file is stored in STEVAL-IME014V1B RAM.
From the RAM, you can run program 1 on the board.
Step 1.
If you are using a high supply voltage, disconnect the USB cable from the PC before starting waveform generation.
Step 2.
Press Push button 1 (PB1) on the STEVAL-IME014V1B board to start generating waveforms.
In Single mode, the waveform stops automatically at the end of the program.
Step 3.
Press Push button 1 (PB1) again to stop the waveform while in Continuous or CW mode.
Step 4.
To store program 1 in the permanent on-board Flash memory (preventing loss of .bin program when
Low Voltage power supply (i.e. VEXT) is removed), press and hold Push button 2 (PB2) for 3 seconds.
The board must be powered externally or via USB during this operation.
Figure 25. Push button 2
LED D1 will light on (red) for a while when the Flash memory is programmed.
