STM32奋斗板步进电机测试,演示的是通过C口的4个口线利用tim2定时器，固定周期产生4路的脉冲信号模拟步进电机的4相8拍控制组合。步进电机采用型号为5V 28BYJ-48的步进减速电机。步进角 5.625度/64驱动板采用ULN2003驱动板。(STM32 struggle board stepper motor testing, demonstration by four port line C port utilization tim2 timer, fixed cycle 4 pulse signal generating analog 4-phase stepper motor control 8-beat combination. Stepper motor with model 5V 28BYJ-48 stepper gearmotors. 5.625 ° step angle/64 driver board with ULN2003 driver board.)

16C954芯片，是一个能够执行串口扩展的芯片，利用该芯片，最多能扩展出4个串口，解决了一般性单片机串口不够用的问题。该源码提供了16C954驱动，利用此驱动，可以快速扩展其他串口功能。(16C954 chip, is capable of performing a serial port expansion chip, using the chip, up to four serial ports can be extended out to solve the general problem of single-chip serial enough. The source provides the 16C954 driver, the use of this driver, you can quickly expand to other serial port functions.)

该项目首先是利用单片机对鱼缸的温度进行智能控制。首先通过外部按键对鱼缸所需温度进行设定。温度传感器 DS18B20 采集温度信息在外围的 LCD 上显示出来。其次是利用光电耦合器判断有无鱼饵，若无鱼饵，发出提示，若有鱼饵，则执行自动投食或手动投食功能。(The project first is the use of single-chip microcomputer to control the temperature of the fish tank. First, the temperature of the fish tank is set by the external button. The temperature sensor DS18B20 collects the temperature information to display on the periphery LCD. Followed by using photoelectric coupler to determine whether the bait, if there is no bait, alert, if there is a bait, automatic throw in and throw food or manually cast and functional food.)
