Mesa-Video makes it quick and easy to display text and 24bit color graphics from any MCU using a single UART serial port […]
Stephen A. Ridley gave this presentation at the recently concluded Chaos Communications Conference (30C3) in Hamburg, Germany. He outlines his recent research into practical ARM exploitation on Linux and Android (for embedded applications and mobile devices). He demonstrates these techniques and discusses how they were discovered using several custom built ARM hardware development platforms. He […]
Frank Zhao posted his STM32F4 breakout board in the project log forum: I really like the STM32 family of ARM microcontrollers. This breakout board is a narrow design that fits perfectly on a breadboard. Every pin is accessible. It has USB, a reset button, and a bootload button. The chip itself has a permanent USB bootloader […]
Viswa writes that ARM Embedded GCC 4.7 reduces code size and now supports all the three host platforms (Windows, GNU/Linux and MAC OS). For more details on this relese see the post by Joey Ye, Engineer Manager in ARM, at ARM.com. Download links can be found here. Via the contact form.
Squonk refers us to this 3-part tutorial on the ARM SWD debug protocol. LPC ARM Cortex-based microcontrollers from NXP can be controlled via SWD, ARM’s Serial Wire Debug protocol and the Coresight register set which allow nonintrusive debugging. This blog post series summarizes use of the SWD protocol to do basic debugging functions on the […]
Bertho is working on a breakout board for the WM8782 I2S ADC and the WM8523 I2S DAC. The boards are intended to be interfaced with an ARM micro-controller. I am working on a project that requires some real audio and I always wanted to play with I2S (attached to an arm microcontroller). So I decided […]
Casai modified a bathroom scale to send his weight info to an Android app through Bluetooth. He documented his built, and released the firmware, as well as the mods he made to the open source Weight Chart app. The scale uses an ARM LPC2103 microcontroller and a serial Bluetooth module to communicate with a Android […]
Brightbluejim let us know that the OLinuXino-Micro ARM9 Linux board is available at Mouser for $30. It runs at 454 MHz, has 64 MB of RAM, an SD-card reader, TV PAL/NTSC video output, one USB High-Speed host port, and an a Pi-tossing 60 GPIO pins broken out. Via the comments
Here is an app note from ARM describing the interrupt behavior of Cortex-M1 microcontrollers. The ARM Cortex-M1 processor was developed for the usage with FPGAs (Field Programmable Gate Arrays) and it is targeting low-cost applications in which costs, ease of use and low interrupt latency are critical. Such low interrupt latency applications can include real-time […]
Olimex released their OLinuXino-Micro, an ARM9 development platform that supports Linux. It runs at 454 MHz, has 64 MB of RAM, an SD-card reader, TV PAL/NTSC video output, one USB High-Speed host port, and an a Pi-tossing 60 GPIO pins broken out. It’s priced around 24 Euros (30 bucks). Via the forum.
Mikro Elektornika is selling STM32 ARM breakout boards with Ethernet PHY for a reasonable price of $24. While they are intended as replaceable MCU cards for their EasyMX PRO v7 development board, you can also buy them standalone and develop your project around them. They come with either STM32F107, STM32F207, or STM32F407 processors, or as unpopulated […]
Development board maker Olimex is brewing up a single board computer, the Olinuxino. The latest revision uses an 1 GHz ARM Cortex A8 based Allwinner A13 SoC, which by the way, comes in a very reasonable 176pin TQFP package. For reals. The new board will feature: A13 Cortex A8 processor at 1000Mhz, 3D Mali400 512 […]
Riktw designed, and got ITead Studio to produce, a Cortex M3 based Arduino compatible board called Simplecortex. The board uses the LPC1769 microcontroller from NXP: The Simplecortex is a microcontroller development board that is shield compatible with the Arduino. The Simplecortex has a fast microcontroller, the LPC1769 from NXP. This is a ARM Cortex M3 […]
Here is an interview with Eben from Rasberry PI, the $25 business-card sized Linux computer. The final product is due to be released at the end of this year. We think its really cool that the main goal of this project is to introduce young children to programing. Via the contact form.
ARM announced that they will release 64bit microcontrollers. The ARMv8 uC will feature a 64bit instruction set, as well as extended virtual addressing. The uCs will have two execution states, AArch32, and AArch64. While the AArch64 handles the 64bit instruction set, the AArch32 executes the existing ARM 32bit instruction set. A compiler for the new […]
This tiny USB stick PC was featured on Slashdot and many other sites. It’s intended as a $25 throw-away computer education tool, and uses an ARM11 with 128MB of RAM: David Braben has developed a tiny USB stick PC that has a HDMI port in one end and a USB port on the other. You […]
