You really don't need an iButton holder. Email me privately if you want to discuss. -marc -----Original Message----- From: pic microcontroller discussion list [mailto:PICLIST@MITVMA.MIT.EDU] On Behalf Of Robert B. Sent: Thursday, August 12, 2004 5:41 PM To: PICLIST@MITVMA.MIT.EDU Subject: Re: [EE:] Ibutton Samples Sample code is very welcome! Especially if it's in assembly or C. I've been rummaging in the samples package and it seems they opted not to include the ibutton holders I requested, so I guess its a homebrew clip until I find a place to order a few from. Maxim's online ordering has a 13-week lead time and doesn't seem to be working anyway. Any ideas for alternate suppliers? ----- Original Message ----- From: "Shawn Yates" To: Sent: Thursday, August 12, 2004 5:26 PM Subject: Re: [EE:] Ibutton Samples > I have made a PIC talk to the iButton.
