Where I demonstrate how to use make and makefiles to automate your build process.

Update#

While this entry accurately describes how to use a Makefile, the approach has changed significantly. See Developing in C for the ATmega328P: Make, Makefile and …

Where I compare the execution speeds of different combinations of boards and languages. I will continue to update this post with other languages and processor combinations.

Table for the impatient#

Where I go into detail as to how I develop code in CircuitPython for the omzlo FIDI board.

Omzlo FIDI#

Technical details#

• Small!: it measures 25.4mm x 22mm (1" x 0.86")
• Microchip ATSAMD21E18A 32-bit Arm Cortex M0+ running at 48MHz, with 256KB …

Where I evaluate an interesting prototyping board using CircuitPython.

Introduction#

I ran across this board, the omzlo FIDI via an Adafruit blog article. I was struck by its size and utility along …

Where I discuss what to do once you’ve downloaded a repository from Github.

Introduction#

I’ve advocated using the AVR_C (among others) repository to learn how to use C instead of the Arduino “C++” language. (I write C++ in quotes …

Where I discuss different methods of automating the process of compiling/linking/loading code for an embedded microcontroller.

Update March 13, 2022#

For automation to work well, it needs to work on multiple platforms along with other automation. For …

Where I discuss psuedo-random number generators (PRNG), finite state machines (FSM) and other software topics.

Where I examine the differences between writing a monolithic program versus a much more modular program.

Important#

While I display some of the code on this page, the absolute truth of working code is on github. Use it to fully understand and/or implement …

Where I demonstrate identifying and solving specific issues with developing code for the ESP32 using the Arduino framework.

Use Both the IDE and the CLI#

While my entries are primarily related to using arduino-cli, I will use the IDE for a couple of …

This is a raw dump of my exploring using the arduino-cli with the ESP32. I wanted to find something that was better than the Arduino IDE, however, not as complex as VS Code/PlatformIO. Using arduino-cli, allows me to use my programming editor, Sublime Text …
