Have you tested connection SW1/SW2/SW3 inputs directly to ground? Please check if wires have good connection in connector. Do you mean UTCOMP-3 or UTCOMP-PRO? UTCOMP-3 have already 4+ years, you can try to reprogramm it, I can share you reprogramming software but please let me know which version exa...

I checked these settings and data logger is in manual mode (disabled by default). Just select in settings -> advanced -> datalogger recording when ignition swith is on and it will be working.

This is good question but I had also strange issue when one of sensors was making some noise on power supply wire due to bad connection to ground. Had you got opportunity to also check compontents I mentioned before? (like C17, C18, T1, T2)

I see in logs old data from 2023-11-26 and later from 2024-02-12. Seems like this is data with old setting and now datalogging is disabled. Please make sure that you have enabled data logging. If you are sure, please share me your utcomp settings file, I'll take a look.

I'm sorry to hear that. It can be something in connection/sensors - have you tried to disconnect all sensors and check if this helps? Just left power supply, ignition signal and display. If yes, then you can try to connect each sensor one by one and try to find out which connection causes troubles. ...

Looks awesome! thanks for sharing it

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...
