GX2431 work fine, read, write etc.

The Dallas DS2431 not so much. Here is the link to images: https://drive.google.com/drive/folders/ ... sp=sharing

I tried all combinations of two pins to Pin 4 and 5, but none can get connected.

It is TO-92, a pack of 10. No, it does not find the wire chip and fails the HW test due to a lack of connection. Is there a main difference between GX2431 and Dallas DS 2431 in function Im missing? GX2431 works fine and passes the HW test. But Im pretty sure pin 4 is ground, are you sure its I/O to ...

Hi ArT, I have been using Revelprog IS with Chinese (GX2431) DS2431 with no issues. Connect the ground pin to Pin 4 and the I/O pin to Pin 5. Now, with the Dallas DS2431 brand, this method doesn't work. When I try reading the chip, it says device not found. I've tried that on at least five chips now...

Perfect Arthur!!

Now I need to write-protect the data memory page 0 (0000h to 001Fh).

Once write-protected, is it possible to deactivate the write protection, rewrite data memory and write-protect them again?

Regards

Thank you for the reply again, First, I need to read the whole chip: data memories, protection control bytes, etc ... basically from 0000h to 0087h (0088h to 008Fh is not readable, is it?). Once read, I need them saved in .bin or any format. The file "RPscript_1wire_DS2431_Read.txt" seems ...

The video uploaded helps, https://www.youtube.com/watch?v=69MQlU2r9k0

Unfortunately, there is no sound on the video, but I gathered the automatic mode allows the import of scripts for function.

Where can I find the script txt files for reading, erasing and writing on DS2431?

This explains a lot, thank you.

How would you approach the task of storing the content of a DS2431 and copying it entirely on a new DS2431?

I don't see a customer script for reading/writing all the address ranges.


Kind regards

Now, I'm talking very specifically about the programmer device and its app. If I write on a brand new DS2431 chip, will it write-protect it by default at address 0080h* to 0084h*? Basically, what I'm asking is what is the difference between writing and reading via app UI functions, and customs scrip...

The link helps a lot, thank you. Ok, so we have: 4 protection control bytes 1 copy protection byte 1 factory byte 2 user bytes = 8 bytes in total First five bytes If programmed to AAh or 55h, it can not be erased. Factory bytes are read-only, so they are definitely not erasable, but 2x user bytes ar...

Thank you for the reply. I tried multiple times, same issue. It is directly connected to the chip as described. This chip has eight rows of bytes; rows 0000 and 0001 seem to be fixed and not affected by erasing, but the rest 6 I can erase, modify and save as long as the top two rows have not been mo...
