我想把自己的设备通过ENC28J60挂到网上，设置怎样的MAC地址才能避免与别人的MAC冲突？

若水

如题

正点原子

一般碰不到冲突的吧...

        uint32_t uid1 = *(volatile uint32_t *)0x1ffff7e8;
        uint32_t uid2 = *(volatile uint32_t *)0x1ffff7ec;
       
        //uint32_t uid3 = *(volatile uint32_t *)0x1ffff7f0;
        mymac[0] = (u8) ((uid1>>0)  & 0XFF);
        mymac[1] = (u8) ((uid1>>8)  & 0XFF);
        mymac[2]=  (u8) ((uid1>>16) & 0XFF);
        mymac[3] = (u8) ((uid1>>24) & 0XFF);
        mymac[4] = (u8) ((uid2>>0)  & 0XFF);
        mymac[5] = (u8) ((uid2>>8)  & 0XFF);
