LQmma7455C52

基于单片机STC89C51和74LS164的多功能数字万用表(Based on microcontroller STC89C51 and 74 ls164 multi-function digital multimeter)

串口与pc机通讯，51单片机例程，只需要修改io口即可实现。(Serial communication with pc, 51 MCU routine, you only need to modify the io port can be realized.)

说明：  单片机c语言 初学者有用 有例子哦 (SCM c language for beginners there are examples of useful oh)

基于C51单片机的波形信号发生器：矩形波，方波，三角波。包含单片机仿真。(Based on the C51 single-chip waveform signal generator: square wave, square wave, triangle wave. Contains simulation microcontroller.)

说明：  通过读出SD卡中320x240像素、16位BMP图片的HEX数据，依次写到屏上，还原图片(Read SD card in 320x240 pixels, 16 BMP picture HEX data, in turn written to the screen to restore the picture)

数码管静态显示源代码，可以直接调入工程使用(Static digital tube display the source code can be directly transferred to the engineering use)

DAC5615的使用，能够控制输出电压为设定电压，并保持恒定。(DAC5615 used to control the output voltage setting voltage, and constant.)

此为51单片机的正弦波产生c程序，可将hex文件烧录到单片机内使用。(This is a 51 microcontroller sine wave generator c program, you can burn the hex file into the MCU.)

基于STC89C52单片机的12864动画显示程序，有详细的代码。(STC89C52 12864 based animation program, a detailed code.)

DS1302+89c51的例程代码，实测可用(DS1302 STM32)
