Robotics and FPGAs (8) - Design of a Multi-Channel Servo Controller PCB (Rev. 1), Part 2 - Analysis and Component Selection
This blog post describes the analysis and component selection stage of the multi-channel servo controller board design and it is during this stage where, sadly, for most of us it all begins to go wrong. It is during this process that every datasheet must be read and reread again and again, until every line of text and every curve in a graph is thoroughly understood. It is at this stage that some, out of despair of a looming deadline, decide to fall on their knees, look skywards and utter words of reverence, utter words of importance or just words.
It is at this stage that others decide it is time to put on their jeans and T-shirt and lock themselves in their study. Only to emerge a few days later wearing a robe and sandals. As you will find out in this blog post we chose to put in a few night shifts to resolve the recurring problems in the design and felt justified emerging with our guru's attire. However, we have known some at this stage of the design process to decide that X marks the spot and continuously aim their heads at it, ceremoniously. Entertaining as this method could be, we prefer ours. However, we recommend you should choose the problem solving method that works for you!
