The ARM chip that wont cost an arm and a leg

A small ARM developmentboard from SMDprutser, that is available on GitHub: Searching the prerequisite Chinese websites to satisfy my shopping fetish I came across a neat little ARM Cortex-M0 chip which is an extremely good bang for buck. I believe it is the smallest chip available in a reasonable hand-solderable package (TSOP8). This board gives […]

LemcUSB: software USB for EFM32ZG (ARM Cortex M0+)

Viswa informs us that the crew have implemented a purely software based USB peripheral for ARM Cortex M0+ devices and a made a tiny Quick start board for EFM32ZG110 MCU. “This software enables Cortex M0+ devices to act as a Low speed USB device. It includes a lightweight USB & HID Stack and can […]

Self hosted toolchain: The MC HCK as SWD adapter

Simon Schubert writes,  “I am happy to announce that we have a self-hosted toolchain: The MC HCK can now act as SWD debug adapter for other MC HCKs, without requiring any other external debug adapters or development boards.” The MC HCK (pronounced: “McHack” [mæk hæk]) is a small, cheap, and versatile ARM Cortex-M4 based microcontroller platform. […]

Turning on/off lights by whistling (Cortex M4 @ 80FFTs/sec)

Limpkin informs us that he recently finished work on his open source project:  Turning on/off lights by whistling Basically, it is an ARM Cortex M4 running 80FFTs per second to detect a whistling sequence.  The project is obviously open hardware/source Via the forum. Check out the video after the break.

Stellaris launchpad based video player

Vinod made this video player using Stellaris launchpad and wrote a post on his blog detailing it’s assembly and operation: I am introducing my new mad project, a video player using stellaris launchpad and a 320×240 color lcd which I got from seeedstudio.  I tried the lcd shield by connecting on an arduino board and loaded some example […]

CMSIS Components used by mbed are now BSD Licensed

Viswa writes, “ARM and has released the components of CMSIS software under a permissive BSD license. CMSIS is common layer provided by ARM for accessing the core registers of ARM Cortex-M processor which inside Cortex-M MCUs. All Cortex-M MCU vendor make use of this library for the software drivers. This was until now under […]

DipCortex – ARM cortex in a dip package with USB

Carl over at SolderSplash Labs has written an article about their new project known as DipCortex: It’s an ARM Cortex M3/M0 in a 40 pin dip package and USB socket. It has two version a NXP LPC1347 M3 and a LPC11U24 M0, the pin out roughly follows a certain range of 40pin 8bit micros.

Open source GCC builds for ARM MCUs and MPU

viswa informs us of a source for “Completely Free Open Source GCC builds for ARM MCUs and MPUs. This seems to be maintained by the official team which maintains GCC for ARM. This is useful for ARM Cortex M / Cortex R processors.” Pre-built GNU toolchains from ARM Cortex-R & Cortex-M processors, together with source […]
