stm32驱动WS2812b实现等带的各种运动(stm32 device WS2812b)

32位单精度浮点数的乘加运算的C编程，感兴趣的可以看一下(Single-precision floating-point multiply-add operation of the C programming, interested can look at)

msp430单片机控制步进马达应用源代码(MSP430 Single-chip stepper motor control application source code)

我使用的是F103VET6，软件IIC控制，改引脚配置后可方便移植。 SDL连接PB6、SDA连接PB7、CS连接高电平，SDO连接高电平的话模块的写地址为0x3A、读地址为0x3B··· ···(I use F103VET6, software IIC control, pin configuration can be easily transplanted. SDL connects PB6, SDA connects PB7, CS connects high level. SDO connects high level telephone module with write address of 0x3A and read address of 0x3B.)

三星单片机资料比较少本程序实现S3F84U8看门狗-使能并喂狗(Samsung SCM relatively little information this program S3F84U8 Watchdog- enabled and feed the dog)

C8051F340实现的USB键盘源代码，包括物理按键键值的获取，USB底层协议的实现、USB数据传输的实现。(C8051F340 USB keyboard source code, including the acquisition of physical keys keys, USB underlying protocol implementation, USB data transfer is achieved.)

程序说明: 此程序用UART1外扩MAX485实现RS-485通信(Procedure Description: This procedure using UART1 extend outside the MAX485 realize RS-485 communication)

信号发生器，液晶1602显示，通过键盘控制AD9833输出需要的波形和频率，可程控(Signal generator, LCD 1602 display, through the keyboard to control the the AD9833 output waveform and frequency, programmable)
