Philips公司推出的新的CAN协议控制器SJA10 0 0近年来得到了广泛的应用。与它的早期产品PCA82C2 0 0相比 ,SJA10 0 0有两种工作模式 :BasicCAN模式和PeliCAN模式。在Peli CAN模式中增添了许多新的功能。文中就如何利用其中的错误分析和自我测试两种新功能去设计调试CAN通信电路进行了探讨 ,并给出了相关的程序框图和代码。
Philips’s new CAN protocol controller SJA1010 has been widely used in recent years. Compared with its earlier product PCA82C2 0 0, SJA1010 has two operating modes: BasicCAN mode and PeliCAN mode. Many new features have been added to Peli CAN mode. In this paper, how to use the two new features of error analysis and self-test to design and debug CAN communication circuit were discussed, and gives the relevant program block diagram and code.
