Thank you for your replies gentlemen. I knew there must be a way to run the DS2483 in mixed voltage system but that detail in the data sheet escaped me. I ignored the extra function of the SLPZ pin and tied it together with Vcc to 3v3, I have now re-wired the device as you suggested with 5v onto Vc

Hi I would like to do some simple trending (graphs) of data from connected 1-wire devices. I have been googling for this and find references to temploggerd but am not sure how to go about installing/using it. I have httpd running ok. Is temploggerd the best tool for simple logging and if so is

David, I've seen no information that the gpio pins are 5v tolerant in any way. This is however where the DS2483 comes into it's own over the DS2482. It is possible to power the 1-wire side from 5v, and the i2c from 3.3v in effect it has an inbuilt level convertor See: http://datasheets.maxim-
