9-ADC

针对MCS-51单片机的硬件结构和原理、指令系统、汇编、中断、定时器、并行扩展等进行了讲解。(The hardware structure and principle, instruction system, assembly, interrupt, timer and parallel expansion of MCS-51 single chip computer are explained.)

说明：  STM32F407 开发EC20代码，EC2状态机代码TCP传GPS数据 - APPMQTTIMEI定义3.15(STM32F407 develops EC20 code, EC2 state machine code TCP transmits GPS data - APPMQ TIMEI definition 3.15)

泰克TDS220示波器使用指导书 ，使用起来很方便，其他示波器使用方法类似(Tektronix TDS220 oscilloscopes use instructions, easy to use, similar to other oscilloscopes use)

基于stm32的蜂鸣器实验源码。需要在对应平台上使用(Based on the stm32 buzzer experimental source. Need to use on the corresponding platform)

说明：  keil c usb数据采集系统 at89c5131的固件源代码 及生成软件 支持3个端点 0.1.2(keil at89c5131)

按键是单片机系统最常用的输入设备之一；几乎是只要需要交互输入，就必须有键盘。本程序提供最常用的4*4矩阵键盘的程序，和4个按键的程序。 (The key is one of the most commonly used input devices MCU system it is nearly as long as the need for interactive input, it must have the keyboard. This program provides the most commonly used 4*4 matrix keyboard program, and 4 key procedures.)

在单片机编程中位图及字库点阵提取程序源代码( The position chart and the fonts lattice withdraw the procedure source code in the monolithic integrated circuit programming )

说明：  stm32单片机通过AD转化输出模拟电压值，并显示在串口调试助手上(The analog voltage value of STM32 MCU is converted by AD and displayed on the debugging assistant of serial port.)

产生步进频率连续波及脉冲波形，及其相应频谱(Produces a step frequency continuous spread pulse waveform and its corresponding spectrum)

STM32F429示波器源代码，实测可用。(STM32F429 oscilloscope source code, the actual measurement is available.)
