The 1-wire (o/w) Protocol – DS18S20

November 13th, 2008 No comments

Hello again,

This post is actually going to become handy on the future posts I am planning for the DS18S20 thermometer. This is a well known and used thermometer as it simple to implement and quite accurate. I will do a brief description of the protocol it uses to communicate with our PIC. Through this protocol we can send commands to the DS18S20 and receive data and responses.
This is actually a brief review of the datasheet of the device which is already very simple to understand. This post is just to introduce the basics of the o/w protocol.

First you can download the latest pdf fromĀ here. Read more…

Hello boys and girls.

A common question I come across quite often, is from a where a beginner should start his/her microcontroller programming adventure. I remember myself wondering exactly the same thing when I was starting out, not too long ago. So which is the best to program? Assembly or C or Basic or… ?

Well I am going to give you my opinion and how well it worked for me. Let’s face it, knowing what is going under the hood is the best experience anyone can get working on any kind of project. If you know exactly how the system works, then you will be able to squeeze every last drop of juice the microcontroller has to offer. Read more…
