Using PyInstaller with Acroname's BrainStem Development Kit

If you are not familiar with PyInstaller it is an application that allows you to bundle a python file or project into a single executable by providing a fully encapsulated environment. The benefit being that you won't need to fuss with setting up a python environment.  Simply execute the application.

Many times pyinstaller can be excuited without any additional commands such as:

Protecting USB devices from Electrostatic Discharge (ESD)

ESD Mitigations with Acroname

The next-generation circuitry in today’s consumer and industrial electronics is smaller, faster, better. Consumers love the innovations. But test engineers are not as enthusiastic. Because that innovation comes with a striking downside: increased susceptibility to electrostatic discharge.

If the USB devices you’re using aren’t built for rugged environments, a catastrophic failure could — and probably will — happen. You’ll have to tell the C-Suite that all your electronic components fried because your ESD mitigations failed.

Using the Acroname Programmable USB 2x4 hub as a software accessible USB switch between two hosts

How to Accomplish a Host Switch With the USBHub2x4

Often a simple USB switch with a physical button is used to switch USB devices between two different host computers. In many cases it would be nice to execute the host switch without physically pushing a button on the device. The Acroname Programmable USBHub2x4 hub allows a user to switch hosts programmatically without pushing a button.

The need for USB-C and power delivery ports in automobiles is speeding up, and the auto industry is adapting to the new demands.

USBHub2x4 Example with National Instruments TestStand

Two example projects for USBHub2x4 With National Instruments

We've recently been getting questions regarding the use of the Acroname USBHub2x4 from within National Instruments TestStand test management software. So we put together two example projects which wraps the BrainStem2 library and provides the critical interfaces you need to do basic things like enabling and disabling a downstream port.
