一个国内电池管理系统(BMS)的源码，主机用的是XC2287M从机是用MC9S08DZ60,之间用CAN通讯,波特率500kbps.可以从中间知道找到一些有用的驱动。(A domestic battery management system (BMS) of the source, the host using a XC2287M slave is MC9S08DZ60, between the use of CAN communication, the baud rate 500kbps. May find useful to know from the middle of the drive.)

键盘控制lcd1602的显示，一个按键实现位置选择，其余两个按键实现数字的加减(The keyboard control lcd1602 the show, a key position select the remaining two buttons digit addition and subtraction)

CAN CAN总线 空调智能节电的应用，汇编语言(CAN CAN intelligent saving air-conditioning applications, assembly language)

C8051F340实现的USB键盘源代码，包括物理按键键值的获取，USB底层协议的实现、USB数据传输的实现。(C8051F340 USB keyboard source code, including the acquisition of physical keys keys, USB underlying protocol implementation, USB data transfer is achieved.)

本项目是基于Cortex-M3 的地沟油快速检测装置，旨在实现“地沟油”快速，现场检测。MCU控制可编程的直接数字频率合成器（DDS）产生正弦激励信号，经过可变增益放大器（VGA）和低通滤波器（LPF）作用于食用油阻抗传感器（实验室制作）信号经过仪器放大器送入微控制器（MCU）的模数转化（ADC）通道，MCU对采集的信号通过快速傅里叶变换（DFT）处理，实现食用油阻抗与相角的检测；USB和以太网接口，可与计算机通讯，以便对采集的数据进行存储和分析。(The project is based on the Cortex-M3 waste oil rapid detection device designed to achieve " waste oil" rapid, on-site testing. MCU control programmable direct digital frequency synthesizer (DDS) generates sinusoidal excitation signal through a variable gain amplifier (VGA) and a low-pass filter (LPF) acting on the oil-impedance sensor (lab produced) to send signals through the instrumentation amplifier into the microcontroller (MCU) modulo conversion (ADC) channels, MCU signal acquisition via Fast Fourier Transform (DFT) processing, oil resistance and phase angle detection USB and Ethernet interfaces, and computer communication, in order to collect data for storage and analysis.)

实时闹钟.1、STM32的实时时钟（RTC）是一个独立的定时器！ 2、RTC模块和时钟配置系统（RCC_BDCR寄存器）是在后备区域，即在系统复位火从待机模式唤醒后RTC的设置和时间维持不变。 RTC这章中，对RTC相关的寄存器的操作特别重要，(RTC Alarm real-time clock timer; keyer; intervalometer; timing device clock; timepiece allocation; configure; collocation; deploy register; tell-table; temporary storage reserve; in support system resetstandby mode awaken; awakening; arouse; rouse; wake up stand)

用单片机c51编写的程序 使用蜂鸣器发出超级玛丽的音乐(C51 microcontroller programs written with use of the buzzer Super Mario music)

与SDK 6.0.0 以上版本配套的 s110 蓝牙协议栈代码.开发 nRF51822 必备.(The S110 SoftDevice is a Bluetooth ® low energy (BLE) Peripheral protocol stack solution. It integrates a low energy controller and host, and provides a full and flexible API for building Bluetooth low energy System on Chip (SoC) solutions.)

将每2片74595做级联，然后再将级联之后的所有时钟线与数据再并联在一起最后对每一组的锁存控制线做单独控制.(Application to do a project, the more I/O, applied to the 74,595 to do the extension, but you want to mount multi-chip 74595, is bound to have a lot to use the I/O port, in order to solve this problem, I will be every 2 sheet 74595 do cascade, and then cascade after all the clock line and the data in parallel and then together (i.e., all 74595 communal clock and data lines, it only occupies two I/O port lines) Finally, for each group latch control lines do individually controlled (equivalent to Chip Select), so that a hardware circuit by a great degree of simplification, both procedures can also share a driving subroutine 74595, to control the type of lock inventory control line, serial data is sent to the port 74595 cascade module. As a result of the hardware and software have a large degree of optimization.)
