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…

When USB robustness and reliability matterFor everyday use — like connecting a mouse or webcam to your laptop — an inexpensive USB hub with enough ports will get the job done. However, in production or test environments, robustness and reliability are paramount. Chasing bugs inherent in…

How to use USBHub2x4 and MTM to work with multiple host machinesIn 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. Host 0 makes all…

Controlling data and power lines independently with HubTool applicationNotice that when the power line is enabled, the Android device indicates it as "charged". After enabling the data lines, the device then indicates that it enumerates as a media device from the USB Hub. Doing…

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…

OVERVIEWA common automation system requirement is to drive or actuate high power loads using low level voltage signals. Motors, solenoids, relays and capacitive loads can be actuated with appropriate circuitry that is only possible using small current/voltage combinations often found in…

PWM (Pulse Width Modulation) refers to the concept of rapidly pulsing a digital signal on a wire. Along with many other uses, it can be used to simulate a varying static voltage. PWM is commonly used for driving motors, heaters, LEDs or lights in varying intensities or speeds.TERMINOLOGYPeriod…
