Psoc 1-wire interface component

[cwallach-weber]

I'd like to access an EEPROM with the 1-Wire protocol. Using a Psoc4 chip and Psoc Creator 4.3.  Are there any drop-in components?

Hi @cwallach-weber,

There is no drop-in component supported to access EEPROM with the 1-wire protocol.

Are you emulating EEPROM in PSOC4 Flash or using an external EEPROM?

You may refer to the Emulated EEPROM CE for a better understanding of the same.

cwallach-weber,

Are you trying to access external memory chip, like Maxim DS27E07, using 1-wire?

[cwallach-weber]

Yes. Its an external memory chip, a DS2431.

Hi @cwallach-weber,

You will have to implement the 1-wire protocol using a GPIO pin of the PSoC4 chip being used i.e., the logic of the 1-wire protocol needs to be written as firmware/C code.
