六个数码管加ARM7,KEIL环境的C和ASM程序-Six digital tube plus ARM7, KEIL environment procedures C and ASM

电机不转，按下启动键，电机旋转，速度为25转/分，按下加1 键，速度增加，按下减1 键，速度降低，最高速度为100 转/分，最低转带为25 转/分，按下停止键，电机停转。速度值要求在数码管上显示出来。-Motor does not turn, press the start button, motor rotation speed of 25 rev/min, press the 1 key, the speed increase by 1 press the button to lower the speed, the maximum speed of 100 r/min, with a minimum of 25 to r/min, press the stop button to stop motor. Speed value of the requirements in the digital tube display.

我上传的一些单片机的资料，KEIL软件的使用，希望对大家有帮助-I uploaded some information on SCM, KEIL software, I hope all of you help

本方法的基本思想就是利用单片机具有的PWM端口，在不改变PWM方波周期的前提下，通过软件的方法调整单片机的PWM控制寄存器来调整PWM的占空比，从而控制充电电流-The basic idea of this method is the use of microcontroller has the PWM ports, without changing the PWM square wave cycle, under the premise of the method to adjust by software MCU PWM control registers to adjust the PWM duty cycle and thus control the charge current
