Why is the bus pirate used? Grab the datasheet PDF daatsheet follow along while we read and write this simple 1-Wire memory.

Parts: 1K 1-Wire EEPROM (DS2431)

Everything is fine until I reset the bus. It is a integreted chip. You are commenting using your WordPress.

Actually, I can only write and then verify what I write if I do a 85 1 0x0f 0x00 0x01 0 1 2 3 4 5 6 7 But when I try to copy data from scratch to EEPROM like this 85 1 0x55 0x00 0x01 0x07 No alternating bits, nothing is written either….

Leave a Reply Cancel reply Ds2341 your comment here Then the data is all 0xFF again. Exist somewhere these information for download them?

But it only uses 1 Wire for data so they call them 1 Wire…. Command 0xf0 followed by a two byte memory address 0x00 0x00 begins the data read process. You are commenting using your Facebook account. To explain completely is not possible here.

At least data can be copied, so we will see what happens…: The first three bytes are the dds2431 code 0x00 0x00 0x07followed by the data contained in the datsheet pad. I want to duplicate the card I already have.

Is there any chance to copy from one ds to another, actually to clone them??? Learn how your comment data is processed. Call it the SmartLED, and use it for large area addressable displays. Maxim has a super nice java base program to test directly your on wire device via the web.

Ok, thanx for quick reply: Uh, I see I am still there, but here goes: Maxim makes excellent devices to access the bus, and naturally software is available.

I want to read data from one DS and write it to another one. Do I just rewrite the memory from the one I have to the empty one?
