if `MY_NODE_ID` is not AUTO

[magicw]

if (MY_NODE_ID != AUTO) {
	// Set static id
       _nc.nodeId = MY_NODE_ID;
	// Save static id in eeprom
	hwWriteConfig(EEPROM_NODE_ID_ADDRESS, MY_NODE_ID);
}

In the stInitTransition function,if MY_NODE_ID is not AUTO,the code will write eeprom one time.if the node reset because some mistakes,It's to bad for the eeprom.Isn't it?

What do you mean?

@magicw,

It will only write to EEPROM if the value differs from the one already stored. So no, this won't affect EEPROM.

[magicw]

@hek For example，If i define MY_NODE_ID is 2,When the node reset,,the logic of this code will write the eeprom again(hwWriteConfig(EEPROM_NODE_ID_ADDRESS, MY_NODE_ID);). Isn't it?

[hek]

hwWriteConfig == eeprom_update_byte

See doc:
http://www.nongnu.org/avr-libc/user-manual/group__avr__eeprom.html

update reads before writing

@magicw ok,thanks!
