应用背景这个例子使用C语言和应用的stm32f401vct6板得到陀螺传感器的值来开启/关闭LED。关键技术mems_l3gd20是stm32f401vct6陀螺仪传感器。这个例子是用来开启/关闭LED基于价值观得到了l3gd20  ；

此代码基于NXP公司的LPC2138ARM7源代码，能够驱动超声波发射与接收器，测距精度小于1厘米，代码注释详细，学习参考价值大，欢迎来下载使用！

Modbus RTU Slave project based on Microchip PIC 16F87X processor and 24LC128 CMOS Serial EEPROM with I2C interface. PIC Modbus RTU slave supports write and read (3 and 16) functions. The data is stored and read from EEPROM via the I2C bus. You can write/read up to 8000 registers. In a single frame can be read/write 32 registers .

通常使用的装置，用于编码和解码诸如异步比特流是一个通用异步接收器/发送器（UART），其将所提供的软件成单独比特序列的数据字节，相反，转换这样的序列比特为数据字节被传递给软件。STM32的处理器包括（最高）五个这样的装置称为USART（通用同步/异步接收器/发射器），因为它们支持超越了基本的异步通信额外的通信模式。在本章中，我们将探讨STM32 USART和（目标）之间的串行通信的USB/ UART桥接器连接到主机PC。
