thereby controlling external devices or circuits.
What is a host controller?
When developing specifications, we should ensure that there is only one host in any USB system. The USB specification is not intended as a network architecture, its purpose is to achieve simple interconnection from peripherals to PCs. A host can be a combination of hardware, firmware, or software. The most common USB host implementation scheme in computers currently is part of the so-called core logic chipset. This host controller device adopts the computing function of PC CPU, supports data storage and movement with system memory, and is implemented as a whole through PC operating system. All hosts must integrate a root hub into the system. The host is mainly responsible for the following tasks:
Detecting the external connection and removal of USB devices
Control process between management host and USB devices
Manage the data flow between the host and USB devices
Collect status and activity data
Power supply for external USB devices
USB system software
Manage the interaction between hosts and devices in the following five aspects
Equipment List and Configuration
Synchronous data transmission
Asynchronous data transfer
power management
Equipment and bus management information
Most operating systems now include a series of “class drivers” that facilitate the connection of peripherals. Class drivers enable peripheral manufacturers to provide products with native support for operating system software, thereby saving the cost of developing drivers and providing drivers for new host systems. Moreover, after the launch of new storage devices, peripherals can directly support drivers. Most operating systems support some common class drivers, including audio class, Human Interface Device (HID) class, imaging class, mass storage class, printer class, and video class. At present, many manufacturers use the above-mentioned class drivers to implement product functions, but they also provide customized drivers or application software to support more functions beyond the class driver specification.
responsible for processing signals from on-site sensors or driving actuator actions. For example, they may need to cooperate with devices such
as BANNER travel switch T30UIPB to receive their transmitted position signals; Or by controlling components such as Burkert solenoid valve 00131421, the on/off of fluid media can be precisely managed.
these modules integrate more complex logic processing capabilities. The core task of a pressure switch is to detect whether the pressure
has reached a preset threshold and output a switch signal. Its function is highly specific and fixed. And modules 5X00247G02 and 1
C31219G01 have the ability to comprehensively judge multiple such switch signals and transmitter signals (such as transmitter 1066-P-HT-60),
and output complex control instructions according to internal logic.
