Script for creating KiCad symbols for STM32 MCUs
ST has recently released a tool for creating projects for STM32 mcu’s called STM32CubeMX . This tool also allows you to plan your pin layout for a selected MCU part. Using the interface you see below, you can select pin features and configuration. You can also label the pins as you desire. After you plan […]

PCB back annotation in KiCAD with Python
KiCAD already provides a tool to automatically annotate your schematics before moving on to PCB. But I prefer to to annotate my components according to their PCB position. That makes it easier to locate a certain component when you have PCB on your hand and schematic is open in the computer screen. Some tools such […]

SerialPlot – Realtime Plotting Software for UART/Serial Port
SerialPlot is my new open source adventure. It allows you to plot data coming through your computers serial port. To be honest, nowadays it’s most likely this will be a USB port, emulating serial port. It supports binary and ASCII data formats. Binary formats include uint8, int8, uint16, int8, uint32, int32 and float. There is […]
