The DS2431 is one wire protocol EEPROM. It is not in the supported list yet. It will be added later.

DS2431 is supported on the device "GQ-4X" from software version 6:36:

perhaps it is still in testing?
I consider all my reading not correct?
to let me know when you can work well with one wire protocol EEPROM, or I'll have to buy another programmer for these EEPROM.

Checked this DS2431.

It is not fully supported yet, it is under testing. The read/write are not fully tested. It still need sometimes to finish the testing.

I confirm the failure with the software 6.38
the reading is incorrect, any data(FF or 00) is contained in the chip, I find myself always 1F read.
openprogrammer works with these chips :(

Any progress with the DS2431? It is not showing up on the supported device list, although it shows in the text based device file in the program folder.
