stm32 cortex m3 pwm输出控制(pwm control)

library for arm display ra8875

Popular processor designs can be broadly divided into two categories: Complex Instruction Set Computers (CISC) and Reduced Instruction Set Computers (RISC).

说明：  件设计思路是利用 MS 的定时器 B 中断执行相应的中断服务程序来产生舵机用多 路 PWM 波.4的 系 统 主 时 钟 频 率 取 8 MHz，设每个定时周期取 250/ =31.25 μs，(The x medium-density performance line family incorporates the highperforfrequency, highspeed embedded memories (Flash memory up toytes), and an extensive range of s and peripherals connected to two APB buses.)

该程序注解清晰，自己用的程序，推荐大家下载。(Clear annotations, their own procedures, recommended download.)

说明：  蓝桥杯大赛各类驱动代码包阔超声波红外线pcf8591等单片机组代码(Blue Bridge Cup Competition Driver Code Package Broad Ultrasound Infrared pcf8591 and other MCU group code)
