Re: UTCOMP-PRO different display

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)

Re: DS2431 erasing issue

Because content is only on addr range 0x0 - 0x7F.

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

Re: Freeze at Boot Logo

How long cable have you tried? Have you tried flat cable? (only flat cable max 2.7m should work)

Re: UTCOMP-PRO different display

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...

Re: DS2431 erasing issue

When you select DS2431 from memory database you can read/write standard memory area (0x00 - 0x7F) - data memory page 0,1,2 and 3. Additional registers (0x80 - 0x8F) are untouched. With custom script tool you can do anything. You can read/write single bytes at specific addr, you can modify additional...

Re: DS2431 erasing issue

It does not change any bytes in this register. After programming standard eeprom area, control bytes stays the same. You need to change them intentionally e.g. with custom script.

Many chips have some configuration or protection bytes which are not accessed in standard usable range addresses.

Re: DS2431 erasing issue

Here you have datasheet: https://www.analog.com/media/en/technical-documentation/data-sheets/DS2431.pdf Memory is organized to 4 pages each 256bits and each page can be permanently Write Protected. You can read control bytes using custom script tool from addresses >=0x80 as described in datasheet pa...

Re: DS2431 erasing issue

It seems to me that it's communiation issue. Please show me how did you connected this TSOC-6 - it's important to make the same length of wires and if you are programming in external circuit - it should be not any additional elements on communication line. REVELPROG-IS was tested with DS2431 TO92 pa...

Re: Tracking Petrol tank by injector pulse and LPG tank by 5v

Fuel level from analog is only limited to PB/ON. But you can use not used other analog value and scale is as tank in range of 0-100. Eg for EGT you can scale it from 0EGT to 100EGT which will give 0-100% fuel level in second tank. You can also later change EGT icon on display to your own https://for...
