基于SPEAr320和STM32的GLC设计

Design of GLC Based on SPEAr320 and STM32

图形化逻辑控制器(GLC)是人机界面(HMI)和可编程逻辑控制器(PLC)相结合的产品。详细阐述了基于SPEAr320和STM32的GLC设计方案,解析其主模块和IO模块的硬件及软件框架,着重分析了两个模块之间的通信机制,展示了一个真正的产品级设计方案。

Graphics logic controller （GLC） is a combination of human machine interface （HMI） and programmable logic controller （PLC）.A GLC design scheme based on SPEAr320 and STM32 is proposed in this paper.By illustrating the hardware and software framework of its main module and IO module,with also the communication mechanism of the two modules,a prod- uct level design scheme is brought out.
