Bluetooth Parking Lock MCU Graphic Bluetooth Parking Lock 51 MCU Pin Function Introduction
Bluetooth parking lock microcontroller What are the characteristics? Bluetooth parking lock 51 microcontroller structure is what? Bluetooth parking lock 51 single-chip solution details. Bluetooth parking lock is a very popular parking lock type in recent years. It can remotely control the parking lock mechanism. If it is combined with a mobile phone APP, it can even realize the real-time status of the parking lock, such as parking lock switch status, battery status, battery usage, etc. , Let's take a look at the function of the Bluetooth car parking lock pointer pin based on 51 MCU. The Bluetooth parking lock system takes 51 single-chip microcomputer as the core. After the cooperation of software and hardware, the electronic and mechanical parts are recombined so as to select the appropriate sensor, so as to achieve all-round intelligent control of the parking lock. Microcontroller-based smart remote control parking lock is composed of single-chip microcomputer as the most cost-saving system of the single-chip microcomputer. Through the combination of software and hardware, and electronic and mechanical cooperation, it realizes the comprehensive intelligent control of the parking lock. The intelligent remote control parking lock is based on the STC12C2052 microcontroller and consists of a remote transmitter receiver circuit, a motor takeoff and landing control circuit, a power supply control circuit, a position sensor circuit, a vehicle position sensor circuit, a communication circuit, and a clock circuit. The main component of the intelligent remote control parking lock based on single-chip microcomputer is the STC12C2052 single-chip microcomputer, with the protection circuit, automatic locking, U, I abnormal warning and other capabilities. The STC12C2052AD series of single-chip microcomputer package and each pin function as shown in the figure: STC12C2052AD series MCU has the following features: 1. STC12C2052AD series single-chip microcomputer is a new generation 8051 series single-chip microcomputer with high speed, low power consumption and super anti-interference. The instruction code is fully compatible with the traditional 8051, but it is 8-12 times faster. Integrated MAX810 dedicated reset circuit, 2-way PWM, 8-channel high-speed 8-bit A / D conversion, for motor control, strong interference occasions. 2. Working voltage: STC12C2052AD series working voltage: 6.0V - 3.5V (5V MCU). STC12LE2052AD series operating voltage: 3.6V-2.2V (3V microcontroller). 3, the working crystal frequency range: 0 ~ 35MHz, running speed is 8-12 times that of traditional microcontroller. 4, the user application space 1K, 2K, 3K, 4K, 5K bytes and other options. 5, the microcontroller integrates 256 bytes of on-chip RAM. 6. There are 15 general-purpose I/O ports. After the reset, it is the weak pull-up mode of the quasi-bidirectional port, which is not only the 8051 traditional I/O port mode. The I/O port can be set in four modes: weak pull-up of the quasi-bidirectional port, strong push-pull, strong pull-up mode, high input impedance or open-drain mode. A single I/O port can drive up to 20mA, but the entire chip should not exceed 55mA. 7, TC12C2052AD series microcontroller does not require a dedicated programmer, no special simulator. The microcontroller can directly download the user program through the serial port (P3.0/P3.1), and the speed is very fast. Write tasks can be completed in a few seconds. 8, the industrial chip operating temperature range of -40 ~ +85 °C, this article choose this type of chip. 9. The size of the 20-pin chip packaged in the SOP-20 package is approximately 10mm×13nm. STC12C2052AD microcontroller contains the central processing unit (CPU), program memory (Flash), data memory (SRAM), timer / counter, UART serial port, I / O interface, high-speed A / D conversion, SPI interface, PCA, watchdog and On-chip R/C oscillator and external crystal oscillator circuit and other modules. The STC12C2052AD family of microcontrollers contains almost all the cell modules required for data acquisition and control. The above is organized by the smart lock Chinese network Xiaobian published Bluetooth parking lock microcontroller basic information, more parking lock knowledge, please pay attention to us!
Black Color Rebar Coupler, which is different from the Silver Color Rebar Coupler. It doesn't processed with strip the ex-circle. So this type of coupler keep the raw material color.
Only the color is black, the material is same with 45C or 40Cr material.
It is
used to rebar mechanical splicing in reinforced concrete structure, and
is designed to connect threaded rebar with diameter from 12mm to 50mm.
