问题： 如何让这两份arduino代码合成为一份且能达到两份分别独立工作的效果？我有的开发板：UNO,mega2560,Due.
项目描述：目前再做一个用arduino作为主控的正弦波逆变器，第一部分电路用arduino产生占空比互补的两路Pwm通过驱动电路给Mosfet经过变压器实现dc12v to dc350v的效果，第二部分电路dc350v输入到由另外两路互补sin码pwm控制H桥逆变逆变电路，经过变压器滤波后出来一个波形很好的正弦波。两部分电路经过两份Pwm产生的代码仿真结果均达到预期结果。
问题描述： 目前有两份代码，第一份是用定时器控制9,10引脚输出电平相反的pwm波。如图
第二份是用定时器控制5,6引脚输出通过频率计算sin数组的pwm波，经过H桥逆变成为正弦波，如图
但是两份代码好像都用到了定时器1，当他们一起工作时仅仅只有第5脚输出了之前单独测试的波形，因为本人水平有限，没能搞清这两份代码之间具体的冲突细节在哪，想请各位能够帮忙修改一下代码，使两份能合成为一份能输出4路电路需要的pwm波从而使电路能够正常工作达到12v直流电逆变为220v50Hz正弦交流电的目的，开发板可以从我有的三种里任选（如果UNO满足不了硬件需要的话），如果实在不能用一个处理器来完成这些事的话能否采用双处理器的方式来完成？
