Micro Python is an implementation of the Python programming language, written from scratch and optimized to run on micro-controllers such as the ones based on ARM Cortex-M cores. Damien George, the developer, also designed the Micro Python board powered by STMicro STM32F405 Cortex M4 MCU for the purpose of running Micro Python. Even though in this project, the star of the show is not the board itself, as Micro Python will run on other platform once it’s open source, let’s have a look at the hardware specifications: MCU – STMicro STM32F405RG @ 168MHz with 1MB flash, 192KB RAM, and an FPU. External storage – Micro SD slot 30 general purpose I/O pins – 5 USARTs, 2SPIs, 2 I2C busses, 14 ADC pins, 2 DAC pins, 2CANs, and 4 servo ports with power. Built-in USB interface Misc – 4 LEDs, a user switch, a reset switch, a real-time clock, and a 3-axis […]
Free Online Courses & Workshops For ARM Cortex-M Microcontrollers
STMicroelectronics and Digikey are co-sponsoring an EE Times University online training course entitled “Fundamentals of Microcontrollers (MCUs): Hands-On Workshop”. The first two 45-minutes sessions will be theoretical and provide and overview of micro-controllers, and explain methods to select an MCU for a given project. The first 1,000 persons based in the US or Canada, who attended the first 2 sessions, will receive a free STM32F4 Discovery Board (ARM Cortex M4). The three next sessions, conveniently taking place about a week later, hopefully after you’ve received your board, will be an actual workshop with STM32F429 Discovery Board. Here’s the detailed schedule for the training: December 2, 2013, 12PM (Eastern Time) – Session 1 – Introduction to Microcontrollers Common microcontroller architectures Pipelining Peripherals: Timers, Communication, Analog December 3, 2013, 12PM (Eastern Time) – Session 2 – Selecting the Right Microcontroller 10 Steps to Selecting a microcontroller What to look for in a […]
MCU Energy Efficiency Benchmark – Freescale KL02, Microchip PIC24, TI MSP430, and STMicro STM32L
Freescale has recently uploaded a video comparison the energy efficiency of several micro-controllers: Freescale Kinetis KL02, Texas Instruments MSP430, STMicro STM32L, and Microchip PIC24. Since it’s a Freescale video, we already know the winner, but the test they performed it still interesting, and it shows drastic performance differences between architectures. The used the following exact MCU for testing: Freescale MKL02Z32CAF4R – Cortex M0+ @ 48 MHz STMicro STM32L151RBT6 – Cortex M3 @ 32 MHz Microchip PIC24FJ128GA308 – 16-bit MCU @ 32 MHz Texas Instruments MSP430F5529 – 16-bit MCU @ 25 MHz Freescale did not really select tough competition such as NXP LPC800 Cortex M0+, but instead a Cortex M3 MCU, and older 16-bit MCUs. I don’t know if Microchip has a new generation of ultra low power 16-bit MCUs , but Texas Instruments, for example, launched MSP430 Wolverine MCUs at the end of last year. So this comparison may not be […]

Thingsquare Mist – Open Source Firmware for The Internet of Things
Thingsquare recently released the source code for the Thingsquare Mist firmware, an ultra lightweight router software (<4 kB memory) for the Internet of Things based on open Internet standards such as IPv6, RPL (Routing Protocol for Lossy networks), and 6lowpan. Thingsquare Mist allows to connect battery-powered wireless micro-controllers to the Internet, and is currently used in applications such as smart light bulbs, connected home appliances, and connected cities. The IPv6 mesh network is composted of nodes with a low power radio that communicate with the Mist router (Green), which in turn connect to the Internet and Thingsquare Cloud backend (Thingsquare Haven) to store the data, and/or receive control commands via Ethernet or Wi-Fi. The end users can then use an App to monitor, and/or control the devices remotely. Thingsquare Mist uses IETF RPL IPv6 mesh routing protocol (pronounced “ripple”) for IPv6 nodes communications. Thingsquare Mist runs on several low-power wireless […]
