Scratchpad

The ScratchPad

Post date: 2 weeks 4 days ago
What is the ScratchPad? 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...

Functional Testing with MTM: LEDs

Post date: 4 months 1 week ago
In this week's video, we show an example of testing LEDs in a board-level functional test system. We used a simple circuit board we created for testing a new light pipe design as an example. The video shows just how easily MTM can be used as an engineering tool and manufacturing test system just by...

How to work with multiple host devices.

Post date: 5 months 1 week ago
In Acroname's latest "How to:" video we demonstrated how to use our USBHub2x4 and MTM to work with multiple host machines.  In short, the best setup for you is determined by the type of handoff you would like between host machines and the flexibility you have to modify those host machines. ...

How many Acroname USBHub2x4's can you connect at once?

Post date: 6 months 4 weeks ago
In this week's video we answered the popular question of: "Can I connect more than one USBHub2x4/BrainStem device to my computer?".  Not only did we prove that the answer is yes, but we also wanted to see exactly how many devices we could connect.  In addition, we also discussed a few methods for...

Up and running with BrainStem using our Python API

Post date: 7 months 1 week ago
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...
Reading a Photoresistor Asynchronously

Reading a Photoresistor Asynchronously blog post

Post date: 6 years 8 months ago
OVERVIEW Photoresistors are used in many applications because they either increase or decrease in resistance depending on the amount of light.  A common application for photoresistors is the triggering of an event when the light passes a certain point.  This example demonstrates the use of a...

Post date: 8 years 9 months ago
OVERVIEW Potentiometers are commonly used in applications where accurate manual adjustment of a setting is required.  The potentiometer changes its resistance depending on the location of the knob, causing a change in voltage that can be read and used to change a value.  This example demonstrates...
