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

3 Tips for Writing External Device Drivers
A major advantage to using a microcontroller today is that embedded software developers typically don’t have to write their own drivers anymore. It’s very common for the microcontroller vendor to provide software frameworks that abstract the hardware and allow developers to make simple function calls to initialize, read and write to peripherals such as SPI, … Continue reading 3 Tips for Writing External Device Drivers
5 Tips for Developing an RTOS Application Software Architecture
Real-time operating systems (RTOS) are finding their way into nearly every IoT device. An RTOSes ability to manage low-level resources and complex timing requirements make them well suited for these applications. It is not uncommon though to struggle with how to design a software architecture that includes an RTOS. In today’s post, we will examine … Continue reading 5 Tips for Developing an RTOS Application Software Architecture
5 Tips for Building a Modern Telemetry GUI
Nearly every embedded system I have ever built has required a graphical user interface (GUI) to monitor and display telemetry. Monitoring telemetry during development can help developers to visualize what the system is doing and play a critical role in verifying and debugging the system. Telemetry in this context is any health and wellness information … Continue reading 5 Tips for Building a Modern Telemetry GUI
Code Quality over Quantity
A short time ago, I was under pressure to repaint the house while simultaneously delivering several high-priority work projects. It was impossible to do both the right way in a timely manner so I began a search to find a company that could cover the paint job for me and came across one named “Quality … Continue reading Code Quality over Quantity
