#163669 - This is drivng me out of my tree!!!!! Responding to: ???'s previous message |
I tried to do a byte write. And for the sake of verifying my code, I start up the display with a known value of 5.
I have three momentary push buttons, left, right, accept. I've coded them for: Left=+2 to 5 on every push and save to eeprom accept = reset display to zero Right=Restore from eeprom whatever is the result of left + x the zeroing works, the update + 2 works, but every time I do a restore, it never returns the any value that should have been saved (at least 5 by the known startup). So everything I know about this eeprom, is.....useless......I just don't get it!! All my other I2C devices require a whole lot more programming, yet this just don't want to hear it. Arrrrrrrrrrrrrrrrrrrrrrr........:( |
