Low-level communication stack module independent of specific bus: AutoSAR

Low-level communication stack module independent of specific bus: AutoSAR

In traditional automotive electronic systems, communication protocols and hardware buses are tightly coupled, which limits the flexibility and scalability of the system. In order to solve this problem, Autosar (Automotive Open System Architecture) proposed a low-level communication stack module independent of the specific bus, namely AutoSAR.

AutoSAR is an open standard designed to provide consistency, reusability and portability for automotive electronic systems. AutoSAR separates software components, communication protocols, and hardware platforms, enabling different automotive electronic systems to integrate and interact flexibly.

In the AutoSAR architecture, the underlying communication stack module is responsible for handling low-level communication tasks, including data packet transmission, error detection and error correction, etc. It provides a set of unified interfaces, enabling upper-layer applications to communicate with various buses transparently without caring about specific implementation details.

Below is a simplified sample code that demonstrates how to use AutoSAR's low-level communication stack modules for packet sending and receiving:

#include <autosar/communication.h>

// 初始化通信堆栈模块
void initCommunicationStack()
{
    CommunicationStack_Init();
}

// 发送数据包
void sendPacket(const uint8_t* data, uint32_t length)
{
    CommunicationStack_Send(data, length);
}

// 接收数据包
uint32_t receivePacket(uint8_t* buffer, uint32_t bufferSize)
{
    return CommunicationStack_Receive(buffer, bufferSize);
}

int main()
{
    // 初始化通信堆栈模块
    initCommunicationStack
