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

|

* @{
|
||||
* Node guarding master pools each node guarding slave at time intervals, called guard time. Master sends a CAN RTR
|
||||
* message, and slave responds. Slave also monitors presence of RTR message from master and indicates error, if it
|
||||
* wasn't received within life time. ('Life time' is 'Guard time' multiplied by 'Life time factor').
|
||||
*
|
||||
* Adding Node guarding to the project:
|
||||
* - Make sure, driver supports it. RTR bit should be part of CAN identifier.
|
||||
* - Enable it with 'CO_CONFIG_NODE_GUARDING', see CO_config.h
|
||||
* - For slave add 0x100C and 0x100D objects to the Object dictionary.
|
||||
* - For master use CO_nodeGuardingMaster_initNode() to add monitored nodes.
|
||||
*
|
||||
* @warning Usage of Node guarding is not recommended, as it is outdated and uses RTR CAN functionality, which is also
|
||||
* not recommended. Use Heartbeat and Heartbeat consumer, if possible.
|
||||
*
|
||||
* ### Node Guarding slave response message contents:

* 0, bits 0..6 | @ref CO_NMT_internalState_t

* 0, bit 7 | toggle bit
