A course on the theories and implementations of real-time systems is about to start on Coursera platform. The course comes from the Finnish University Åbo Akademi, and lasts 5 weeks of low workload (2-3h per week). The instructor entices the learner by showing a famous real-time system failure, during the landing of the Apollo 11 on the surface of the […]

libopencm3 for the license-sensitive Cortex-M developer

April 12, 2015

I was thinking of starting a new open source project that should run on STM32 boards, and I realized that it would need a lot of low level code that accesses many different peripherals. One of the first libraries that comes to mind, and I bet it’s the same for many Cortex-M developers, is ARM CMSIS. ARM […]

Dangerous Prototypes recently announced the availability of the open source Bus Blaster v2 in their shop (here the announcement). The Bus Blaster is an USB tool to debug microcontrollers and embedded cores in general, and its design is completely open source. I already did a post on the first version of the Bus Blaster, but […]
