Ulong to eeprom

[secs]

Hi all. Tinkering around for a quick couple of timers I am simply using an Arduino Mega 2560.

I need to write and read a ulong to and from eeprom and found some code on these forums I think was being used for a pic
I have attached a couple of images. I simply made the code into macros. I have a feeling a need a couple more bits but does what I have done/copied correct?
Data_out and DIN are Ulong

Thank you very much for the reply,

i will have a look on that topic.

I want to discuss something else regarding EEPROM and interrupts as well but i don't know where is the appropriate forum location to post my thought and questions. Any idea or suggestions?

Thanks again
George

Use this part if you are using Flowcode 6. Or 'General Programming' if the subject is not linked to a specific version of Flowcode. Before posting, use 'search' (right top of the page) to check if it has been discussed before.

Hi, i did not realized that this was posted for V6. Excusse me for that.

My question was for V4 of flowcode. I tried the example in the link above but i get errors while compiling.
