Basic Analog for Digital Designers

"There is a long gap between engineering college and mid career in a non-engineering position, but technology marches on so a simple method of keeping abreast with the latest developments is required. This application note starts with an overview of the basic laws of physics, progresses through circuits 1 and 2, and explains op amp operation through the use of feedback principles."

Basic Analog for Digital Designers - Application Note
AN9510.2 October 19, 2004

This is an Analog Reference for the Embedded Engineer. An Application Note from Intersil Tech Reference.

MAX1169 ADC and PIC Microcontroller

What is the use of a Robot, which cannot perceive its environment in detail. Where can a Control system be effective, if it does not get a "feedback" about its actions. How could one do Analysis and Research or Verify, when he cannot Measure a parameter with good accuracy and resolution.

ADC are the Eyes and Ears for a uC, this brings the Real world as Numbers within the CPU. Without ADC a uC is like a Frog in the Well and has to create an Imaginary World for himself. That is beyond the scope of Engineering.

Bring your favorite PIC Microcontroller to his senses. Give him an ability to Perceive the Reality around him. Get him an Analog to Digital Converter and don't forget to code.

MAX1169 ADC and PIC Microcontroller.

MAX1169 ADC is better than 4 1/2 Digit Value. For me the Intersil chip is a Benchmark. Beyond 5 1/2 Resolution may be needed only for Scientific Research.

I would add, 2 1/2 is like Analog Meters/Bar Graphs, 3 1/2 for Control systems, 4 1/2 for T&M and beyond 5 1/2 is for R&D.

Technical Writing and Support

Proper documentation of product after design include Engineering Documentation, Production and Purchasing Inputs, Service Manuals, Operator Manual, Quick Reference Cards. Charts and Tech Catalogs.

There are more important documentation before you start planning product design. These impact everything else, but we should not get stuck up on Red Tape.

Docs, Notes and Logging are essential and need to be simple. ISO 9000/Agilent - "Document what you do. Do what you document."

LaTeX Equation Editor - Equation Maths

Writing Mathematics on the Internet. Witing equations is difficult in a doc, they have to be font independent, that implies images. Webapps do it well.

Also try AbiWord a free word processing program. Excellent for a wide variety of word processing tasks. Has MathML and LaTex input.

  1. OpenOffice.org is an open source office suite and has an equation editor which can export formulas in MathML
  2. GtkMathView is a C++ rendering engine for MathML documents.
  3. MathML Software - Editors

LaTeX Equation Editor -Equation Maths

The interactive LaTex equation editor let's you write and download equations in seconds! You can now integrate the sitmo equation editor with iGoogle or your own site. - sitmo
