Worlds Most Powerful Cortex Microcontrollers

STMicroelectronics, today announced the introduction of its new STM32 F4 series of microcontrollers. This extension to the STM32 platform is based on the latest ARM Cortex-M4 core, which adds signal-processing capabilities and faster operations to the already outstanding portfolio of STM32 microcontrollers; the new series, which is available now, reinforces ST’s leadership and claims the title of highest-performance Cortex-M processor-based microcontroller range in the market.

Correct for errors in a cul-de-sac

While the micromouse is exploring the maze, there are plenty of opportunities for it to make mistakes and end up out of position somehow. Equally, there are plenty of places where there are opportunities to correct any errors that have occured. The single cell cul-de-sac or dead-end is a perfect place for both. (more…)

I2C use on the STM32F103R Medium Density Devices

I2C or Inter Integrated Circuit ( sometimes just referred to as just two-wire interface ) is a great method of individually communicating with over 100 devices on only 2 wires. However I2C as a whole requires a reasonable amount of protocol overhead so its not the fastest method of communicating with outside peripherals. But it is very good at reducing wiring on space critical designs due to the fact that only 2 data lines are required to enter the processor. (more…)
