STM32单片机可以通过以下代码实现重启(core_cm3.h)。同时如果利用AT命令进行无线通讯,服务器后台和客户端之间用MODBUS通讯即4G+MODBUS RTU,可以利用F05写单个线圈的方法结合软件重启实现远程MCU重启
if (IO_OUT0) { delay_ms(100); __set_FAULTMASK(1); NVIC_SystemReset(); //关闭所有中断,系统复位; } __STATIC_INLINE void NVIC_SystemReset(void) { __DSB(); /* Ensure all outstanding memory accesses included buffered write are completed before reset */ SCB->AIRCR = ((0x5FA << SCB_AIRCR_VECTKEY_Pos) | (SCB->AIRCR & SCB_AIRCR_PRIGROUP_Msk) | SCB_AIRCR_SYSRESETREQ_Msk); /* Keep priority group unchanged */ __DSB(); /* Ensure completion of memory access */ while(1); /* wait until reset */ }
