Basically, what I want to achieve is a canvas-based web interface to control an Arduino through Raspberry Pi. The use case is that a user navigates to raspberrypi:8080 to display a canvas. Then aft
Category: Motherboard
Computer case motherboards are also called mainboards, systemboards or motherboards; they are divided into commercial motherboards and industrial motherboards. It is installed in the chassis and is one of the most basic and important components of a microcomputer. The motherboard is generally a rectangular circuit board, on which is installed the main circuit system that composes the computer, generally there are BIOS chips, I/O control chips, key and panel control switch interfaces, indicator plugs, expansion slots, motherboards and plug-in cards. DC power supply connectors and other components.
Serial port – Windows UWP Windows.devices.serialCommunication.SerialDevice does not work
Is it just me, or is it a bug?
serialPort = await SerialDevice.FromIdAsync(Id); serialPort is always null, even if Id is not.
I need this to work. Now I just write very “fast and dirty”
Storage area network – Fiber Channel: Overlifting LTO tape when bus reset
We have a situation that I hope customers can understand better.
This is what happened:
>has The tape library of the LTO tape drive is connected to a Fibre Channel environment
