I write about using Forth with embedded processors as well as practical electronics and inexpensive test equipment.
Work-in-progress: Where I create Fast PWM words in Forth.
Arduino Forth HAL
This page contains a Forth hardware abstraction level (HAL) much like the m328def.
Why the microcontroller datasheet is so important to programming in Forth.
FlashForth is a phenomenal Forth for learning how to use Forth in an embedded system.
ESPForth is one of the easiest and least expensive ways to learn Forth.
Op Amp Resources
Here are links to Op Am information, primarily for the design of simple, practical amplifiers.
Labrador Lesson: Programmable Bias and Gain
Using potentiometers for programmable bias and gain on the amplifier.
Labrador Lesson: AC Signal Analysis
Using the Labrador to examine the amplifier’s AC signal response.
Labrador Lesson: DC Sweep
Using the Labrador and a DMM, perform a DC sweep of an inverting amplifier.
Designing an Inverting Amplifier with Bias
I’ll use this amplifier to perform multiple tests using the Espotek Labrador.
Labrador Lesson: Software Bug
How to resolve a specific software bug on the Labrador.
Labrador Lesson: Installation and Calibration
How to install the software then perform a hardware calibration.
