OneWire device with family code B3

[256FF]

I'm want to emulate a onewire device of my printer chip. It is alike the DS2433 but chip family is B3. Can anyone help me? In the attachment there are some dumps of the EEPROM.

You can read out the eeprom but can't solve this task? Seems odd. Just load your *.txt into notepad++ with hex-editor-plugin or any other similar hex-editor and copy your data into an uint8_t array and write it into your emulated device with the default DS2433-Example:

auto hub = OneWireHub(pin_onewire);
auto ds2433 = DS2433(0xB3, 0x01, 0x01, 0x33, 0x24, 0xD0, 0x00);

constexpr uint8_t memSTRATASYS[] = {

void setup()
{
    Serial.begin(115200);
    Serial.println("OneWire-Hub DS2433");

    // Setup OneWire
    hub.attach(ds2433);

    ds2433.writeMemory(memSTRATASYS, sizeof(memSTRATASYS), 0);

    Serial.println("config done");
}

I just had to replace the spaces " " with ", 0x" after copying the hex-values.... Code is untested but should work. The alternative is to directly modify the memory by changing the constructor in the ds2433.cpp / replace clearMemory()....

Thanks for the description. Did not realize that it is so easy to add the content.

I didn't want to be offensive, but it looked like you solved 90% on your own. And i think the previous task was harder.

No problem. ATM I'm a bit familiar with r/w the Stratasys chips but reading up on to get knowlegde with the arduino. I'll be back with more questions soon. ;-P

Back again. Now I'm juggling with the UID. When dumping the EEPROM I get 8 Double Hex blocks of the original Chip. b3 bb dc 06 d0 14 10 1e

But in the DS2433.h I only have 7 blocks available. Do I have to exchange https://github.com/orgua/OneWireHub/blob/master/src/DS2433.h#L15 to family_codd = b3 ? and then add the other 7 blocks to the other file?

This means instead of auto ds2433 = DS2433(0xB3, 0x01, 0x01, 0x33, 0x24, 0xD0, 0x00);

the line should look like this: auto ds2433 = DS2433(0x01, 0x01, 0x33, 0x24, 0xD0, 0x00, 0x11);

I think i will close this issue for now since there are no problems regarding the lib itself. Your problems are more suited for an arduino-forum. Answers for your c/c++-questions should have been already discussed at stackoverflow. For the questions regarding onewire even wikipedia would suffice. And nearly every slave-datasheet answers the ROM / UID Question on the first 3 pages.
