你想读哪些寄存器，你得到什么值？设备必须连接到CAN收发器，总线必须终止，否则它永远无法正常启动（或退出配置模式）。您可能需要查看SPI总线上的数据以查看出错。将RPI SPI时序与ARDUINO进行比较。你可以在两个单元之间反转SPI时钟，或者使数据在错误的边缘上改变。汤姆

Which registers are you trying to read and what values are you getting?
The device has to be connected to a CAN Transceiver and the bus has to be terminated or it won't ever start up properly (or exit Config mode).
You may need to look at the data on the SPI bus to see what is wrong. Compare the RPi SPI timing with the Arduino. You may have the SPI Clocks inverted between the two units, or have the data changing on the wrong edge.
