This may be a stupid question, but I'll ask it any way. Could not find the answer.
My code does compile but I have not gotten to the part where I can test it yet.
I have defined a structure and created an array of structures. It holds the configuration settings for my sensors. What determines the address within the atmega2560 eeprom in the code? Is it the "0" in (void*)0 ?
eeprom_read_block((void*)&systemConfiguration, (void*)0, sizeof(systemConfiguration));
eeprom_write_block((const void*)&systemConfiguration, (void*)0, sizeof(systemConfiguration));
The eeprom_read_block line is in the last part of setup().
My entire code (less the tabs) is:
/* This is the code for the Master Alarm Controller (MAC).
* atmega2560 with 4 hardware serial ports.
* structures do compile.
* Need to match the structures sensor nodes and remote interface panel (RIPs) nodes
* then need to test the code.
* added the EEPROM block writing and reading arrays of structures to the EEPROM
* NEED TO TEST ???not sure what controls the location in EEPROM
* see http://playground.arduino.cc/Code/EEPROMWriteAnything
*
* This code is for the mega2560
* It will use 3 serial ports. Serial. is for debug to the pc monitor terminal
* Serial1. is for RS485 comm with the sensors
* Serial2. is for RS485 comm with the remote control panels (RIPs)
* Serial3. light controls ????
*
*
*2015-12-27:
*comm with remote panels....structure to receive:
*panel unitID,
*unitID to change,
*parameter to change,
*type of change: silence alarm,
* cancel alarm,
* bypass unitID,
* min/max,
* mode: norm, day & night,
* save setup,
*
