EEPROM Offset Not Working #19

Open jdylanknight opened 1 month ago

jdylanknight commented 1 month ago

Hi y'all!

I am quite new to this and am working through the offset settings for my first unit.

I am not getting consistent results with the test_enable un-commented in Arduino IDE Unit.ino after using EEPROM_Write_Offset.ino to set the offset to 100 initially as is recommended -- it seems to be hitting random letters and not homing at all. It will spin a few full rotations and stop on a letter, then execute the following sequence in the code:

int calLetters[10] = {0, 26, 1, 21, 14, 43, 30, 31, 32, 39};

As I have tested the magnet for correct polarity and the hall sensor functions fine outside of this test, what else may I keep an eye out for?

Additionally, when setting EEPROM, it is recommended to start with the value of 100. I looked all over and am still unsure what unit this is in or how to adjust it should I see a consistent yet incorrect homed letter I can correct for (e.g., "B" instead of the " " as it should be).

Thank you in advance for your patience and any information y'all may provide. I am otherwise rocking and rolling with this project.

We discussed this privately and the issue seems to be related to the Hall Sensors. However it has highlighted it is not obvious what the offset code is doing so will look to update the readme with more information regarding this

Thanks Jonny! I appreciate your help on my question and will update you once I have tried other hall sensor modules. :-)
