Nearly every microcontroller contains option bytes, fuses, or some method to control general settings on the processor. These settings often control features such as whether debugging is enabled or disabled, flash can be written or read, and even how the processor will boot. In this post, we will explore how to program the STM32 option … Continue reading Programming the STM32 Option Bytes using SEGGER J-Flash

The Siglent SDG 2042X Arbitrary Waveform Generator
First off, this is not an ad or paid blog. I was recently working on a project where I needed to generate several different waveforms simultaneously and my old, trusted and true GW Instek SFG-2110 Synthesized Function Generator just wasn’t going to do the trick. I considered using MicroPython and slapping some FETs on the … Continue reading The Siglent SDG 2042X Arbitrary Waveform Generator
Tools – STM32Cube.AI
Machine Learning has the embedded systems industry buzzing as new tools and capabilities become available for us developers to implement in our systems. Machine Learning on Arm Cortex-M type microcontrollers is still relatively new, but there are some very interesting tools available that make it easier for developers to integrate a trained model into their … Continue reading Tools – STM32Cube.AI
Cyclomatic Complexity Measurements with pmccabe
A common question that I often receive is “What McCabe Cyclomatic Complexity tools should I use?” Now this is always a partially loaded question because while there are quite a few out there that I really like, most developers are really asking what free tools I can recommend to them. One of my favorite ones … Continue reading Cyclomatic Complexity Measurements with pmccabe
5 Reasons the ESP32 is an Intriguing Solution for the IoT
The ESP32 from Espressif has been around for quite a few years now. For many of those years the ESP32 seemed to have the reputation that it was a low-cost maker module for hobbyist and developers interested in one-off projects. Over the past year I’ve seen the ESP32 not only designed into several production systems … Continue reading 5 Reasons the ESP32 is an Intriguing Solution for the IoT
ASN Filter Designer
Digital signal processing (DSP) has become an important tool in the embedded software developer’s toolbox. DSP allows a developer to modify a signal in ways that wouldn’t be otherwise possible. While DSP is often used in audio applications, developers can use DSP to create digital filters that can be used to remove analog hardware from … Continue reading ASN Filter Designer
The MicroPython Pyboard Series-D Module
MicroPython has been an interesting project to watch over the last few years. If you’ve not heard of it, MicroPython is an open source project to port Python to run in a real-time, microcontroller-based environment. The ports typically are for Arm Cortex-M processors but there are several ports that run other architectures from Microchip and … Continue reading The MicroPython Pyboard Series-D Module
Protect Your Tools when the Hardware Bites Back
I recently had an exciting experience where I was working with a client who was having I2C issues with a new board they had developed. To speed up the debugging process, I connected my I2C/SPI bus tool to their development board and custom-built hardware. Being able to view the I2C traffic would allow a quick … Continue reading Protect Your Tools when the Hardware Bites Back
Tools – SWD Adapters every Developer should have
Even though SWD and JTAG have well defined standards, there are still several different size connectors and footprints that developers need to be able to support. It often feels like every programmer and every development board is using a different and incompatible connector and cable. In this post, I’m going to share with you the … Continue reading Tools – SWD Adapters every Developer should have
Tools – Real-time Application Visualization Using Tracealyzer 4.2
It has often been said that a picture is worth a thousand words. When it comes to debugging embedded software, a picture is worth a hundred thousand lines of code. For most of my career, I’ve always felt apprehensive about running code on a target and verifying a few external features to say that the … Continue reading Tools – Real-time Application Visualization Using Tracealyzer 4.2
