Adriano - the subject line should have [PIC]: in it so that people who are interested in PIC material can receive your message. I'll repost this for Adriano with the proper [PIC]: tag. Somebody who speaks Italian may wish to communicate with Adriano and get a clear picture of what he wants and help him post it in English as the requirement is not totally clear. I read him as saying. "I want to use a 16F84 with serial devices such as I2C, memories such as 93C46, sim cards and MM53200 decoders. There is lots of material on the net dealing with this sort of application but none that I can find deals with the sort of things that a beginner needs to know. What I want is not just a circuit of something that works but rather information that will help me learn the principles involved. I have a particular project in mind once I learn enough - a PC logic state analyser. My website is http://www.geocities.com/adriano-sar/" BEAR IN MIND THAT THIS "TRANSLATION" MAY BE VERY WRONG. Anyone with any comments? Russell McMahon From: "Adriano Venturini" To: Sent: Sunday, August 18, 2002 6:04 AM Subject: HELP for serial devices!Hi, like you behave when you must join a pic for example 16F84 and serial device what the bus i2c, the memories type 93c46, a sim card, a decoder MM53200? In the net so much is material and so much rising for many applications, few are the publications that teach like behave in these cases. That of which I need is not a plan already fact, but learn to attach these types of devices. What I ask if anybody of you has a method from follow the study with the max precision or what he there has furnished the better resulted. Goings to attempts, a particular software, the PC, a analyser of logical states.
