ChibiOS is an open source RTOS for embedded systems. It’s comparable with FreeRTOS; but for my money is a nicer project. Comes with a hardware abstraction layer – i.e. device drivers (kind of). That means we target the ChibiOS API rather than a particular platform. A lot of manufacturers supply a device layer specific to their… Read More »

STM32F4-based Logic Analyser

I’ve been meaning to try this project out for a while… It’s a basic logic analyser built on the STM32F4DISCOVERY board. The STM32F4 runs at 168MHz, so we’ve got a fair bit of bandwidth available. Nothing like a real logic analyser, but the project page reports 20MHz. For most of the microcontroller-based work I do,… Read More »
