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.)

说明：  NBiot M5310-A模块 COAP协议发送数据（MSP430F149）(NBiot M5310-A COAP MSP430F149)

0.96寸OLED显示12864英文驱动，可显示2种字体(0.96-inch OLED display 12864 English driver, you can display two kinds of fonts)

DataScope 串口虚拟示波器 一款非常不错 串口调试软件 具有多个串口通道 同时传送多个数据

51单片机的智能交通灯系统的源代码，可以用键盘更改交通灯的时间(51 single intelligent traffic lights system source code, you can use the keyboard to change the time of traffic lights)

hc08飞思卡尔单片机上实现ＡＤ转换，已完全调试通过(Freescale HC08 achieve single-chip AD conversion, debugging has been fully adopted)

这是avr单片机键盘实验的程序很好很实用在此先给大家，非常全面的(Avr microcontroller is a good keyboard is very useful experimental procedure we give in this very comprehensive)

用于TEC制热片的PID控制算法，使用IAR平台。(PID control for TEC, based on IAR platform)

利用单片机MSP430f149单片机实现的 实验八 ADC与LCD(The use of single-chip MCU MSP430f149 experiment eight ADC and LCD)

说明：  利用GPIO控制无源蜂鸣器发声，播放音乐。使用SysTick延时，使用位带操作寻址IO口引脚。(GPIO is used to control the voice of passive buzzer and play music. Use SysTick delay, use bit band operation to address IO pins.)
