Cycle precise delay loop in C++

Implementing a cycle-precise delay loop in C++ for embedded system

In a recent work on Marlin's printer firmware, I found a pending pull request about waiting for precise, ideally nanosecond timed, delays.

While it looked like easy at first, the implementation proved tricky. This post explains t...

Advanced debugging of MKS Robin Nano (STM32) board

If you need to debug your printer's firmware, you've probably read my previous post already. If not, I advice you to read it.

This post is about solving the remaining issues and/or shortcomings with the debugging so that a debugging session is...

Installing RGB leds strip on your 3D printer

This post contains a small tutorial to describe how to install a strip of RGB(W) leds (typically WS2812B) on your printer. If you don't know what a led strip is, it looks like this:

RGB LED strip powered on with rainbow colors

It's a long flexible PCB with many RGBW (red/green/blue/white...

How to debug Marlin's firmware with a ST-Link V2 probe

Debugging Marlin with ST-Link V2

If you ever used a Marlin Firmware on your 3D printer, it's very likely you or someone else has built the firmware for your printer. However Marlin is a treasure full of features and it's very unlikely you'll get the exact gem you were expecting.

For example,...
