基于ds18b20 及51单片机 程序数字温度计设计程序 (Ds18b20 and 51 of the SCM process-based digital thermometer design process)

As the computer hardware developing and the fast advances of computers in the last several years, Monte Carlo particle filter algorithms, which origin Monte Carlo methods, have become popular again. The Monte Carlo particle filter algorithms in this paper use the concepts of sequential importance sampling. The base idea of particle filter is the approximation of relevant probability distributions using a set of discrete random samples with associated weights.

说明：  A5130是一款图传模块，程序实现了使用stm32作为主控mcu，通过stm32的硬件四线spi总线控制A5130的寄存器实现两个模块之间的正常通信。(A5130 is a graphics module. The program implements the use of STM32 as the main control MCU. It controls the normal communication between two modules through STM32's hardware four wire SPI bus to control the register of A5130. Fast transmission rate, no packet loss)

本程序是关于LED在单片机里的流水等的演示程序，已经经过测试(This program is on the LED in the SCM in the water and other presentation program, has been tested)
