一直开在这个task 里面,请教下是不是步骤不对?
上位机是否有报什么错误;查看是否checksum是classic还是enhance.
上位机没报错,打印了lin_State->currentEventId,一直是3 6 9 13, 3和6 应该是正常,9表示Readback data is incorrect,是说发的数据内容不对吗?
16进制显示,是这样,有点不太理解,0xd 应该表示“RX overrun flag”
ID = 0x02是主机接收,我看上位机设置成发送,主机和从机同时抢占总线,从机竞争失败,导致回读错误
溢出可能是你在中断加了打印,把打印去掉,不建议在中断里面打印东西
确实是这样,感谢!
