UART by STM32. you can use it

stm32 cortex m3 pwm输出控制(pwm control)

arm启动代码的详细说明和实现,可以更好地了解ARM结构(arm to start the detailed specification and implementation of the code, you can better understand the ARM architecture)

控制小车的寻迹，避障，刹车等功能，算法较为简单，基本以驱动电机为主(Control of the car tracing, obstacle avoidance, braking and other functions, the algorithm is simpler, basic to the main drive motor)

ARM监视串行口，将接收到的字符发送到字符再发送给串口，即按PC机键盘通过超级终端发送数据，开发板将接收到的数据再返还给PC，在超级终端上显示。(ARM monitors the serial port, the received characters are sent to a character and then sent to the serial port, ie the PC keyboard to send data via HyperTerminal, the board will receive the data and then back to the PC, in the HyperTerminal display.)

设计的是一种基于ARM的自反馈程控放大器，它由ARM主控模块、放大模块、滤波模块、电源模块、键盘和液晶显示模块构成。以ARM1138作为主控芯片，通过对输出信号进行数据采集及处理，实现放大器增益校正与闭环控制，达到精确程控放大器增益和实时显示的目的(Design is a programmable ARM-based self-feedback amplifier, which consists of ARM control module, amplifier modules, filter modules, power modules, keyboard and LCD display modules. To ARM1138 as the master chip, the output signal by data acquisition and processing, calibration and closed-loop amplifier gain control, programmable amplifier gain to achieve accurate and real-time display purposes)
