Re: Sanguinololu 1.3a EEPROM

Hi,

I assembly Prusa i3 with Sanuguinolou 1.3 ATMEGA 1284PU and Popolou stepper driver, preloaded with Marlin firmware. I open Repetitier-Host, use EEPROM CONFIGURATION to calibrate and step values . It works. Then press SAVE EEPROM. But the data was lost the next day, after power down of both PC and Prusa.

I am not familiar with ATMEGA. Would someone tell if I need to to use another PC software, or it need a EPROM writer to change EEPROM setting and configuration.h file?

Best Regards
Tsui
