Installation

To install, start the installer executable and follow the instructions as shown in Fig. 3 below (from left to right).

Fig. 3: AS7058 Software Installation Steps

Note: The EVK software is available for download. Please contact the ams OSRAM support team (support_aws@ams-osram.com) for the download link.

Setup

1. Connect the micro USB cable to the board and plug it into your

computer.

2. Then, press the S2 button for one second to turn on the

AS7058 EVK.

3. The green LED on the Microcontroller board will light up as

soon as the board is powered.

4. The green LED (H1) on the mainboard will light up as soon as

the board is powered.

5. Afterward, start the EVK GUI software.

GUI Overview

Fig. 5: Overview of the GUI

The Graphical User Interface (GUI) consists of seven main

segments (Fig. 5):

•Device Connection: To connect the AS7058 EVK to the

software.

•Configuration Presets: Afew configuration presets are

provided to help the user quickly start using the device.

•Sensor Configuration: Adjusts the settings for each

parameter.

•Register Map: Displays the value of each register and

can control the sensor status.

•Applications: This tab contains vital signs application-

related parameters.

•Measurements: This tab displays HRM, SpO2, ECG &

Bioimpedance readings along with a graph of the ADC

count.

•About: Shows information regarding the software and

Python versions.

•Refresh list: If Windows does not automatically

recognize the device, press this Refresh button and wait

for the board to be recognized.

Note: The other segments are only activated after the connection to the

evaluation kit is established.

GUI Overview –Device Connection Tab

Fig. 6: Overview of the GUI –Device Connection

After launching the EVK GUI, the “Device Connection”

tab is displayed.

The GUI has two ways to communicate with the

device:

1. Wired connection via the micro USB connector.

2. Wireless connection via the BLE (refer to page

4).

The GUI application is available on Windows-based

PCs and macOS.

GUI Overview –Configuration Presets Tab

Fig. 7: Overview of the GUI –Configuration Presets

A few configuration presets are provided to help the user quickly start using the device.

These can be chosen from the “Configuration Presets” Tab. Each file comes with a

description, letting the user know what measurements can be done using them:

•AS7058 EVK: SpO2 on finger - SpO2 monitoring on the finger at a PPG sampling

frequency of 100 Hz. The SpO2 result is not calibrated.

•AS7058 EVK: PPG & ECG - This is a test configuration for simultaneous ECG &

PPG measurements using the EVK.

•AS7058 EVK: ECG 1kHz - For an ECG measurement on the finger using the EVK.

The sampling frequency is 1 kHz and the total gain is 128.

•AS7058 EVK: ECG & Lead-off -For an ECG measurement on the finger and lead-

off detection using the AS7058 EVK.

•AS7058 EVK: HRM & RRM - Heart Rate and respiration rate monitoring on the

finger at a PPG sampling frequency of 200 Hz, with PRV measurement enabled.

•AS7058 EVK: EDA Measurement - This is a configuration for measuring changes

in a person’s skin resistance.

•AS7058 EVK: BioZ Measurement - This is a configuration for measuring a

person’s body impedance with the AS7058 EVK.

•AS7058 Wired-WB: HRM on wrist - Heart Rate monitoring on the wrist when a

wired wrist demo is connected.

•AS7058 Wired-WB: SpO2 on wrist - SpO2 measurement on the wrist when a

wired wrist demo is connected.

To save the current configuration settings, click the Save Configuration button (Fig. 7).

This opens the Save Configuration File dialog box. Enter a file name, choose the file

location, and save it as a JSON file. Lastly, click Save to save the file.

To load a JSON configuration, click the Load Configuration button (Fig. 7). This opens

the Select Configuration File dialog box. Then, select the JSON configuration file you

want to load, and click Open.

GUI Overview –Sensor Configuration Tab

Fig. 8: Overview of the GUI - Sensor Configuration

The device parameters can be configured in the Sensor

Configuration tab. This tab presents the various functional

blocks of the AS7058 as separate rectangular blocks. After

choosing a configuration preset, the enabled blocks are

highlighted in green, and the disabled blocks are shown in

grey.

The parameters contained within each block can be

monitored/modified by selecting the individual blocks.

Note: Any change in the configuration parameter takes

effect only after it is saved - before exiting the corresponding

block.
