Introduction

The RHFAD128 is specifically designed to sustain ionizing dose and heavy ions for space applications by using a high-end proven CMOS technology.
This device is a low-power, multiplexed eight-channel 12-bit analog-to-digital converter for conversion from 50 ksps to 1 Msps. The architecture is based on the successive-approximation register with internal track-and-hold. The RHFAD128 features 8 analog inputs that can be programmed to be either 8 single-ended or 4 differential inputs using the control register bits. The output serial data are straight binary and are compatible with SPI.
EVAL-RHFAD128V2 is the evaluation board of the RHFAD128.
This board can be connected to a NUCLEO-L476RG and be monitored with a graphical user interface (GUI): the RHFAD128_GUI.

Getting started

System requirements
The RHFAD128_GUI software needs the following system requirements to perform:

Table 1. System requirements

Main components

NUCLEO-L476RG| STM32 Nucleo development board
Mini-B USB cable| With USB data support
AKI_BIN_for_NucleoL476RG| Software for Nucleo
RHFAD128_GUI| RHFAD graphical user interface
EVAL-RHFAD128V2| RHFAD128 evaluation board
Operating system| Windows OS
STSW-LINK009| SW for Nucleo connection

Hardware configuration
RHFAD128 (EVAL-RHFAD128V2)

Connect the EVAL-RHFAD128V2 to the Nucleo using the following pinout.

Software configuration

Nucleo connection

1. Connect the NUCLEO-L746RG to the laptop using a Mini-B USB cable:

2. Please make sure that STLINK is installed and up to date:

3. Launch the RHFAD128_GUI

   • a. Unzip the zipped folder RHFAD128_GUI.zip
     Figure 5. There are two documents: RHFAD128_GUI folder containing the RHFAD128_GUI.exe to launch on the laptop – AKI_Bin_for_NucleoL476RG.bin to upload in the Nucleo

4. Upload the binary into the STM32 Nucleo board
   Connect the Nucleo board to the PC using a USB Mini-B cable, drag and drop the binary file to the Nucleo board (NODE_L476RG)

   • use the binary file: AKI_Bin_for_NUCLEOL476RG.bin

Use of the GUI

In the RHFAD128_GUI folder, click on the RHFAD128_GUI.exe file to open the GUI. The following window must appear.

Troubleshooting

Device not found

Issue:

• The Nucleo board is not detected
  Resolution:

• Please connect the appropriate Nucleo board

• Be sure that STLINK is installed and up to date

• It is also better to have only one Nucleo board connected to the computer

• Then click on “OK”.

Connection issue

Issue:

• In case of unwanted disconnection or a problem in reading the device, the message “Connection issue” appears in the Single read mode communication box.

Resolution:

• Close the GUI and disconnect/reconnect the Nucleo board and restart the GUI
• If the problem persists, check if the board is correctly connected.
