thereby controlling external devices or circuits.
The third and fourth of the five elements are input and output (I/O), respectively. I/O is a channel for exchanging data and signals between external devices and microcontrollers. In microcontroller design, dedicated peripheral circuits for external devices are required to perform data input, output, and communication. The basic operations corresponding to input and output include CPU read and write. Input/output is called a port, and its address is called a port address. According to the different data and signal exchange functions with external devices, it needs to be divided into input ports and output ports.
5. Bus
CPU、 The memory and I/O functions constitute the basic internal functional units of a microcontroller, but only by connecting the CPU, memory, and I/O through wiring so that signals can flow through each unit, can the control of the microcontroller be achieved. Therefore, the fifth element of the microcontroller is the bus. The following figure is an example of a microcontroller signal flow. The various functions of the microcontroller are connected by multiple signal lines, which are called buses.
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 1X00188H01 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.
