第一版代码，为了在EEPROM保存参数的时候走STM32的CRC，让Codex修改了一下，现在的效果是无法存储，codex表示原因是CRC方法不同，修改到一半今天的额度使用完了，有待后续解决CRC的bug

|

* LSS protocol is according to CiA DSP 305 V3.0.0.
|
||||
*
|
||||
* LSS services and protocols are used to inquire or to change the settings of three parameters of the physical layer,
|
||||
* data link layer, and application layer on a CANopen device with LSS slave capability by a CANopen device with LSS
|
||||
* master capability via the CAN network.
|
||||
*
|
||||
* The following parameters may be inquired or changed:
|
||||
* - Node-ID of the CANopen device
|
||||
* - Bit timing parameters of the physical layer (bit rate)
|
||||
* - LSS address compliant to the identity object (1018h)
|
||||
*
|
||||
* The connection is established in one of two ways:
|
||||
* - addressing a node by it's 128 bit LSS address. This requires that the master already knows the node's LSS address.
|
||||
* - scanning the network for unknown nodes (Fastscan). Using this method, unknown devices can be found and configured
|
||||
* one by one.
|
||||
*
|
||||
* Be aware that changing the bit rate is a critical step for the network. A failure will render the network unusable!
|
||||
*
|
||||
* Using this implementation, only master or slave can be included in one node at a time.
|
||||
*
|
||||
* For CAN identifiers see @ref CO_Default_CAN_ID_t
