数码时钟显示，用8位LED软件译码动态显示，P0为字段码,P2为位选码，数码管共阳， key0为位选键；key1为加“1键；key2为减“1”键。-Digital clock display with 8 LED dynamic display software decoding, P0 code for the field, P2 election code for the digital, digital tube were positive, key0 bond election for the position key1 to add " 1 button key2 to reduce the" 1 " button.

TLC5615 DA转换器驱动程序（KEIL）-TLC5615 DA converter Driver (KEIL)

这是一套基于单片机的温湿度测量系统，里边附有设计的原理图，pcb图，以及烧写程序代码（keil c51编写的）。温湿度传感器使用的是dht11，性价比高。该系统除了能显示温湿度以外，还能设置温湿度报警阈值。设计的pcb板，小巧，使用。这是本人的毕业设计，有实物为依据，具有可操作性。-This is a single-chip microcomputer-based measuring system of temperature and humidity inside with schematic design, pcb plans, as well as the programmer code (keil c51 prepared). Temperature and humidity sensors are used dht11, cost-effective. Except that the system can display temperature and humidity outside, but also set the temperature and humidity alarm threshold. Pcb board design, compact, use. This is my graduation project, there is the physical basis of operational.

修改后的PDIUSBD12完整固件源码，实现51单片机的USB接口，完全通过测试。-revised PDIUSBD12 integrity of the firmware source code, achieving 51 SCM"s USB port and fully tested.

6段数码管分别显示，时，分，秒，四个按键，K1（P0.0），K2（P0.1）， K3（P0.2），K4（P0.3），四个按键用来调时间的，按下K1，所有位都清零显示，然后按下K2，秒在闪烁，继续按K2分闪烁，不段地按K2 秒--分--时切换着闪烁，在某位闪时按下K3相应位加一，确认调整，按K4，取消调整再按K1。在K1按下以后才有调时的功能，如果K1没有按下，按别的键没有反映。这为了在加点按键功能留着用 -6 respectively of the digital control, when, minutes and seconds, four keys, K1 (P0.0). K2 (P0.1), K3 (P0.2), K4 (width), the four keys to the transfer time, press the K1, All spaces are reset, then press K2, the scintillation seconds, according to K2 pm flickered. not according to K2 of seconds-- minutes-- when switching to flicker in certain press the flash-K3 corresponding increase in a confirmed adjustment by K4, then canceled K1 adjustment. K1 in the press will only be made after the transfer of function, if K1 pressed by other key is not reflected. This points to the function keys used Retention
