Based on datasheet, it's working like OTP, so when you protect it, you can not change it anymore:
Once programmed to AAh or 55h this address becomes read only. All other codes can be stored, but neither write protect the address nor activate any function
It's for DS2431, only comment is wrong. Would you like to save it to single file? Usually EEPROM is separate file and control registers is other file (it needs 2 operations for read) but if you need it in single operation it's no problem, I prepared you script for reading all area. PS. 88h to 8Fh ar...
Here you have examples, you may need to modify it to your needs. If you need, you can use one script before DS2431 and one after DS2431 as presented on video. If you write me what would you like exactly achievie, I'll try to help, for example with automation mode you can do with one click: - write D...
Ok seems like sth with internal DC/DC converter. There are few +5V lines used for internal logic. +5.2V is used for MCU. +5.2V ON/OFF (based on ignition signal, T1 is used) is used to power internal peryph, like additional flash memory. +5V ON/OFF (which is +5,2V ON/OFF after D11) is used to power d...
Interesting. Please observe it carefully, you may have voltage drop on 1m flat cable. There is no resistors in series, but there is DC/DC converter on OLED board for VDD (+5V -> +3.3V)
If you would like to set protection bytes you will need to do it with script. You can make own script and use it with automatic mode viewtopic.php?f=32&t=913
Here you have connector pinout for OLED: 2024-02-21 110710.png VDD = +5V I checked datasheet of NHD-3.12-25664UCW2 and it does not tolerate +5V power supply (max 3.5V) - seems it does not have DC/DC converter on board. Interface is the same, but unfortunately it will not work, it will be damaged aft...
