C8051-PCA

标题： NEC红外线接收解码程序引用定时器 效果： 运行程序，按遥控器按键，在数码管上显示相应的地址码-控制码（以16进制显示） 分两段，前段是地址码，后段为控制码，用点隔开，显示两字节，忽略反码(Title: NEC infrared receiver decoder program reference timer effect: run the program, press the button of the remote control, digital display corresponding address code- control code (displayed in hexadecimal) separated into two parts, the preceding address code, after paragraph control codes, separated by dots, two bytes, to ignore the anti-code)

手持振动仪，自动通过傅里叶变换，提取峰峰值，来自动调整震动的幅度，(Handheld vibration, automatic Fourier transform, peak extraction, to automatically adjust the amplitude of vibration,)

C8051F120,使用12864实现DAC显示，非常实用的C8051F120例程。(JUST FOR c8051f120。this is an useful CODE。)

STM32读取GPS信息并跟踪并短信发送到目标手机(STM32 reads GPS information and tracks it and sends it to the target cell phone by short message)

说明：  很详细的原厂HT1621规格书(Ht1621 specification)

说明：  stm32f103c8t6 驱动0.96oled四角屏显示曲线，很好的绘制各种曲线(Stm32f103c8t6 drives 0.96 OLED quadrangular screen display curve, which can draw all kinds of curves well.)

说明：  该程序为大家提供贪吃蛇程序例程。给大家一个参考，来实现简单的贪吃蛇游戏功能(This program provides you with snake-eating routines. To give you a reference, to achieve a simple Snake game function)

本制作适用于初学单片机51者,简易波形发生器的制作(This production is suitable for beginners microcontroller 51, the production of simple waveform generator)

其原理很简单，就是MSP430F14x系列单片机Timer A模块有一个比较/匹配功能，利用这一功能可以输出任意频率、任意占空比的方波，把这些方波输给蜂鸣器就可以播放了。当然要让蜂鸣器播放《最炫民族风》，最大的挑战是写C语言版的“乐谱”。所幸小时候学过五六年的小提琴，再加上物理竞赛的背景，因而对于乐谱、乐理、音频、节奏等等关键概念都略懂一二。废话不多说了，直接上源代码： (The principle is very simple, is MSP430F14x Series MCU Timer A module has a compare/match function, the use of this feature can be output at any frequency, arbitrary duty cycle square wave, square wave lost these can play a buzzer. Of course, to make the buzzer play " the most unusual national wind" , the biggest challenge is to write C-language version of " music." Fortunately, the child learned the violin in 2056, coupled with the physical contest background, and thus for sheet music, music theory, audio, rhythm, etc. have little knowledge of twelve key concepts. Ado, directly on the source code:)
