Updated: Where I discuss a simplified approach to development automation using make in AVR_C, add the ability to use Arduino tools.

Introduction#

The previous explanation provided the Makefile from Elliot Williams and can be viewed here. I have made …

Where I discuss the various methods of increasing execution speed in Forth and demonstrate the ease in doing so.

Introduction#

In this entry, I showed the relative speeds of board/language combinations from a ARM M0 running CircuitPython to a Pi Pico …

Where I discus debouncing buttons in Flashforth as well as indexing arrays.

Introduction#

Elliott Williams had a great post several years ago as to the best solution to debouncing buttons. The technique worked extremely well in C, and I wanted to attempt …

Where I describe in detail how to compile a new version of FlashForth.

Introduction#

Its helpful to be able to compile a new version of FlashForth. A simple reason is to increase the baudrate from 38400 to 250000, increasing your productivity. It …

UPDATED: This page contains a both a Forth hardware abstraction level (HAL) much like the m328def.inc file for AVR programming in C and an example of debouncing buttons.

New Words#

This HAL provides the words:

I/O Words#

The Arduino pins are defined by bit …

Why the microcontroller datasheet is so important to programming in Forth.

The Datasheet#

The ATmega328P datasheet is critical to understanding how to program the 328P. Exploring it with Forth is the joy of Forth as Forth allows you to interactively test …

Where I use Forth to develop a better understanding of the ATmega328P PWM capabilities. Revised from original post on April 17, 2021

Introduction#

Pulse Width Modulation (PWM) is a technique used to control analog …

Where I describe how to use Forth with an Arduino Uno and make it easier to program the Uno in Forth.

Introduction#

The Arduino Uno benefits from an incredible software framework. Between the programs already developed by the Arduino organization, and the …

Where I demonstrate your first embedded application, much like the C Language “Hello, World” program, blink.

A simple program, Blink#

To begin to understand how to program in Forth, I’ll iterate over several versions of blink.

Light the …

UPDATED: Where I describe how to use FlashForth, a phenomenal version of Forth for the ATmega328P to learn how to use Forth in an embedded system.

Notes for Video#

This video demonstrates the ease of loading FlashForth on to an Arduino Uno, and …
