Hi Vasile,
In 1.c, you say "prepare your mind as the product will be manufactured in 1000 pieces. In this way you'll avoid a lot of mistakes". Can you be more explicit about classical/usual mistakes ? Maybe few examples, real-life ones ? In 1.d, can you give pictures of good and bad PCB designs, regarding ground & power nets, etc... ? (for the bad ones, you can use mine :)) In 1.e, can you tell me (us) more about testing points ? I have indeed observed these points in big PCBs (DVD players, etc...), and was wondering how they were used. I guess there's a testing specification document. In steps you describe, you manufacture PCB before writing firmware. Shouldn't a (prototype) firmware version be written before ? How do you test your design ? If not entirely, at least some part of it ? You've now guessed my question: how do you prototype your project ? Or, maybe, what can be prototyped, and what shoudn't be prototyped because of some hardware issues not compatible with a prototyping platform (PWM with breadboards, for instance ?) This actually makes me think about software development methodologies. What you describe makes me think about the waterfall model: you build your project as independent steps, when you finished one, you go to the next and never come back to previous. As a hobbyst and beginner, it's important to have a global overview, the "big picture", as soon as you can. Test/experiment a schematic, an idea, from hardware to software, and regurlarly iterate through this process 'til you reach a point where you're quite confident moving to PCB manufacture is reasonably possible. It's highly furstrating to produce smoke with a freshly made PCB you've spent hours on... Thanks for your advices Cheers, Seb 2010/4/5 vasile surducan <[email protected]> > Hi all, > > I've wrote a short article with my ideas about designing an embedded > project.
