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 […]
Sjaak has published a new build: When you get started on ARM microcontrollers things are very overwhelming at first… After coping with the first few hurdles like installing a toolchain and IDE, the next part should be getting a tool to program the chip. Many vendors have some kind of bootloader burned in the chip, […]
Sjaak has published a new build, the STM32/GD32F103 QFN32 breakout board: Uptill now I used 0603 sized resistors and capacitors but for this project I switched to 0402 to save a few mm on the board. I have soldered many challenging chip packages so I felt confident. The technique is the same as for bigger […]
Sjaak writes: The battle isn’t AVR Atmega vs Microchip PIC anymore.. More and more people are moving to ARM chips. As easy as it sounds but it isn’t. ARM is an company that invented the ARM chips, but doesn’t has a silicon fab, instead they license the design to several silicon manufacturer like ST, NXP, […]
Viswa informs us that the Lemcu.org 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 […]
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. […]
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.
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 […]
Viswa writes, “ARM and mbed.org 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 […]
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.
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 […]
