4 ADS1x48EVM GUI

The ADS1x48EVM requires a communication driver that is installed automatically. However, this FAQ can help troubleshoot driver-related issues if any arise.

The following steps describe the ADS1x48 GUI software installation:

  1. Connect the micro-USB-to-USB cable from the PAMBoard directly to a USB port on the computer. Do not connect the cable through a USB hub.
  2. Open up the web-based GUI available on the EVM landing page (ADS1148EVM-PDK or ADS1248EVM-PDK).
    1. First-time users may be prompted to download and install the browser extension for Firefox™ or Chrome™ and the TI Cloud Agent Application as shown in Figure 4-1. Installing the TI Cloud Agent is a one-time download and installation.
  3. Refresh the GUI such that a green signal displays and the Hardware Connected indicator shows in the bottom status ribbon (see Figure 4-2).

When connected, the ADS1x48EVM GUI has multiple pages to help navigate and control the ADS1x48EVM:

The following sections step through each GUI page in more detail.
