Serial port transmission structure is to convert the structure into an array, and then transfer the char in the array.
That is struct——->> char [] ;
Then char[]———>> struct.
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.
BIOS – How to disable VGA on a new server … reversible?
The strange problem is here. I have a server with 1GB RAM, but it shows 768MB at startup. I found the reason for it-that is, it has a shared memory with the main RAM Onboard graphics card. Running
What happens to the Node ID in the CAN bus?
In principle, two nodes are not allowed to have the same ID segment in a CAN-bus network, but what if the two nodes have the same ID segment?
Before the experiment, we must first have a clear un

Change the BIOS settings on the SuperMicro system via script
I see that Dell & HP have a program that can change the B IOS settings remotely or through scripts/files.
Does anyone know how to do it on the Supermicro system? To do this, or is there a sys
How to read data from serial ports in R
I want to draw real-time data from the serial port. I think R is a good tool for this job. I encountered a stumbling block while trying to read data from the serial port (COM4) I have verified that the data is entered via terra term (and closed the session before trying R), but I can’t seem to get anything in R.
