Anonymous users2024-02-07If you just test your program, you can solder a minimum system board yourself, and if you want to participate in electronic design, you have to make a minimum system board yourself, because the smallest system board is easy for you to expand later.

Anonymous users2024-02-05The models have 8-bit single-chip microcomputer, 16-bit single-chip microcomputer, and 32-bit single-chip microcomputer.
Bit single-chip microcomputer. This kind of single-chip microcomputer has strong control functions, the most complete variety, because of its rich resources and powerful functions, mainly used in industrial control, intelligent instruments, household appliances and office automation systems.
Bit single-chip microcomputer. The CPU is 16-bit, the computing speed is generally higher than that of the 8-bit computer, and some single-chip microcomputers have an addressing capacity of up to 1MB, which contains A D and D A conversion circuits in the chip, and supports high-level languages.
Bit single-chip microcomputer. The word length of the 32-bit MCU is 32 bits, which is the top product of the MCU and has extremely high computing speed. Representative products include Intel's MCS-80960 series, Motorola's M68300 series, and Hitachi's Super H (SH) series.

Anonymous users2024-02-0480C51 is used as BAI when learning a microcontroller
The example is mainly the single-chip microcomputer of Du Shao.
The 80C51 MCU belongs to the Zhimcs-51 series DAO MCU, which is opened by Intel.
hair, its structure is an extension of 8048.
The shortcomings of the 8048 have been improved, with instructions such as multiplying (mul), dividing (div), subb, comparing (push) bit data pointers, Boolean algebra operations, as well as serial communication capabilities and 5 interrupt sources. It features a 40-pin Dual In Line Package (DIP) with 128 RAM units and 4K with two 16-bit timing counters, two external interrupts, two timing count interrupts, and one serial interrupt, and four 8-bit parallel inputs. The 80C51 has an internal clock circuit, but requires an external quartz crystal and trimmer capacitor, and the system uses a crystal oscillator frequency of 12MHz.
Because the system performance of 80C51 meets the requirements of system data acquisition and time accuracy, and the product output is rich and wide, and the application is also very mature, it is used as the control core.

Anonymous users2024-02-03The main frequency is the main frequency, ROM and RAM, and the number of input and output ports.
Beginners of single-chip microcomputer should at least understand the working principle of single-chip microcomputer, let him talk about it. Then you should know the system clock, interrupts (external, internal, interrupt response flow), timing counters (timer usage?). What is the use of a baud rate generator? >>>More
Let's put it this way, depending on your attitude towards learning electric guitar. In fact, I personally recommend learning acoustic guitar first, and then switching to electric guitar, which is a little more reasonable. Of course, if you don't want to learn acoustic guitar and want to go straight to the guitar, you can also do it. Next, let's talk about equipment. >>>More
Trouble. Just buy a pair and use it.
In my experience with keil, header files are best used to describe some functions, not to define variables or anything, and variables are better defined above or inside the main function. >>>More
This is to use the button to control the control direction of the stepper motor.
