基于STC15W系列单片机，实现一种常用的MAX7219驱动的8位数码管显示模块的程序。(Based on STC15W series MCU, a program of 8-bit digital tube display module driven by MAX7219 is implemented.)

说明：  LED显示，简要说明源码功能，使初学者更好入门(LED display, a brief description of source code, enabling beginners a better entry)

一调试好了，放心使用吧，很好的，保证你会满意的。(A debugging good, feel free to use, very good, guarantee that you will be satisfied.)

说明：  在stm32F407上通过操作按键来操作指示灯蜂鸣器还要pwm波(On stm32f407, the indicator lamp is operated by operating the button, and the buzzer also needs PWM wave)

雷达仿真的c程序，我自己写的 站长大人，情尽快开通帐号，救急(radar simulation c procedure, I wrote the director of adults, and a quick opening of account and save)

小三极管成型机源码程序，实际工程案例应用源码程序 (Small transistor forming machine source programs, the actual application source programs Projects)

说明：  19264液晶时钟，带按键，两页显示，带闹铃，带农历属相，二十四节气显示，功能非常全(24 solar terms with lunar week alarm)

For this project you need a 3.7v power supply that prepared by LM317 regulator. So you need MAX232 for connect uart to pc .my AVR chip project is Mega8 that you can program on any Avr chip have 2kbyte rom. In bascom spi hardware don’t work correct, so I have to software spi ,but the software spi configure have low speed into hardware spi.

峰值电流控制的BOOST,DC-DC电路，48V转80V，具有ZCS环境(Peak current control BOOST, DC-DC circuit, 48V switch 80V, with ZCS environment)
