实用经济型豆芽机程序，运用c51单片机，极大的降低了成本，对于家庭更加实用(Practical economical bean sprouts machine program, greatly reduced the cost, for the family more practical.)

说明：  STM32F103系列模拟USB串口实验，使用KEIL平台(STM32F103 series simulation USB serial port experiment, using keil platform)

采用四端法测试欧姆电阻，并把结果显示在lcd上，采用c8051(Four-terminal method using ohm resistors, and the results displayed in the lcd, using C8051)

两份基于51单片机的交通灯，包括原理图，proteus仿真，PCB，实训报告等。是我单片机实训时的成品，调试成功的。(Based on 51 single two traffic lights, including schematics, proteus simulation, PCB, training reports. SCM training when I was finished, debugging success.)

说明：  32位单片机HR8P506上运行FreeRTOS，HR8P506是一款Cortex-m0内核的国产单片机，支持2.5-5.5V的宽电压，36KB Flash和8KB SRAM能够满足绝大多数的应用开发。(32-bit MCU HR8P506 runs FreeRTOS. HR8P506 is a domestic MCU with cortex-m0 kernel, which supports a wide voltage of 2.5-5.5v, 36KB Flash and 8KB SRAM which can meet most application development.)

说明：  东西、南北两干道交于十字路口，各干道有一组红、绿、黄三个指示灯，指挥车辆和行人安全通行。南北方向为主干道，通行时间为35秒；东风方向为支干道，通行时间为25秒。通行时间最后3秒，绿灯灭，黄灯闪烁，黄灯闪烁完毕变更通行车道。通行时间由数字显示器显示，黄灯3秒闪烁不单另计时。 特殊情况控制通行方式控制，用按键开关K1控制主道通行，支道禁行，K2控制支道通行，主道禁行，特殊情况控制通行放行。 有紧急情况时用按键开关K3控制两道均为红灯。(The east-west and North-South arterial roads intersect at the intersection. Each arterial road has a group of red, green and yellow indicator lights to guide vehicles and pedestrians to pass safely. The north-south direction is the main road with a traffic time of 35 seconds; the east direction is the branch road with a traffic time of 25 seconds. At the last 3 seconds of the traffic time, the green light is off, the yellow light is flashing, and the yellow light is flashing to change the traffic lane. The traffic time is displayed by the digital display, and the yellow light flashes for 3 seconds, not only for another time. Under special circumstances, control the way of passage. Use key switch K1 to control the passage of main road, Branch Road, K2 to control the passage of branch road, main road and special circumstances to control the passage and release. In case of emergency, use key switch K3 to control two red lights.)

基于430的AD9954驱动程序，单频，FSK等全有。(430 AD9954 driver, single-frequency, FSK, such as whole.)

TCS3200D光感及顏色偵測IC 三顆偵測不同位置光源副程序源碼(TCS3200D sense of light and color detection IC three detect the different position of deputy program source code)

本程序是芯片AT45DB041B的ISP的模拟编程，是一个比较实用的程序，推荐大家看看。(This program is the chip AT45DB041B ISP s analog programming, is a more practical procedure, we recommend a look.)
