Acroname's hubs are a robust hardware solution to many common usb related tasks: remotely simulating a manual plug-cycle, charging (or not charging) batteries on connected devices, and switching control between two host computers.
The problem USB devices often need to be disconnected and reconnected (plug-cycled) or reset. The reasons for plug-cycling a USB device are as varied as types of USB devices themselves. In service, the simplest solution to many USB-related problems is to reset the errant host machine or USB device.
The BrainStem scratchpad is a shared memory on a brainstem module which is accessible from both the host and Reflex code. It serves as a simple interprocess communication channel for separate Reflex routines, as well as a communication channel between the host and reflex code running on the BrainStem module.
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.
Acroname, Inc. has been bringing robotics and automation systems into the hands of engineers for more than 20 years.
Check out our new YouTube video "Up and running with BrainStem using our Python API".
This video details how to properly configure your system to communicate with our Brainstem modules. It includes: installing Python, pip, and the BrainStem API (.whl). Once everything is up and running a basic example using a USBStem module is shown. Configuration, along with the examples, are shown for both Windows and Macintosh platforms (also compatible with Linux).
Acroname, developer and distributor of expandable hardware and software products for embedded robotic, automation, control systems and manufacturing testing, has unveiled the first fully programmable USB hub for automated regression testing, manufacturing test and measurement.
Acroname's BrainStem® technology is a foundational tool for bridging the gap between hardware and software systems. BrainStem controllers gather and relay peripheral information to other systems, which may be a host computer, additional microcontrollers or an array of sensors and testing equipment.
