ARM Introduces DSP ‘Lab-in-a-Box’ For Education Combining STMicro STM32F4-Discovery Board and Wolfson Audio Card

DSP (Digital Signal Processing) courses at University have traditionally used software simulation packages (Matlab), or hands-on labs using development kits costing around $300 per student. In order to reduce costs, ARM University program and their corporate partners have launched a DSP ‘Lab-in-a-Box’ so that university students can learn DSP and audio systems with hardware selling for about $50, or over 80% cheaper than previous educational hardware. A typical DSP Lab-in-a-Box (LiB) would come with: STMicroelectronics ARM Cortex-M4-based STM32F4 Discovery MCU board Wolfson Microelectronics and Farnell element14 Wolfson Audio Card. ARM Keil MDK-Professional development tool with a 1-year renewable software license. Teaching materials such as lecture slides, code samples, and hands-on lab manuals. STM32F4-Discovery board features an STM32F407VGT6 MCU (ARM Cortex-M4F core) with 1 MB Flash, and 192 KB RAM, sensors (motion and accelerometer), a digital microphone, and audio DAC, a micro USB connector, and various buttons and LEDs. The Wolfson […]

USB2Go ARM Cortex M3 Development Board for Android Smartphones (Crowdfunding)

Many MCU based development boards such as Arduino or mbed platform connect to a computer via USB for power and programming, at least during the development stage. USB2Go, however, is designed with a micro USB port to connect directly to your Android smartphone, although it can also be used for standalone project, and an Arduino compatible baseboard is also available. This board powered by an STM32 ARM Cortex M3 MCU is however mainly destined to interface hardware such as LED, servos, sensors to your smartphone via micro USB providing both power and a communication channel with your Android device. USB2Go hardware specifications: MCU – STMicro STM32 ARM Cortex M3 MCU @ 72 MHz with 128 KB Flash, 64 KB SRAM USB – Micro USB for power and programming Headers – 2x 12 pin headers giving access to GPIO, ADC, PWM, UART, I2C, SPI… Debugging I/F – JTAG 20-pin to SWD […]

U-Boot & Linux BSP for STMicro STM32 Discovery Board

If you want to run Linux on STM32 Discovery board, more exactly STM32F429 Discovery board, it’s now possible thanks to Emcraft Systems’ BSP for STM32F429 Discovery Board. It will only work on that particular version of the discovery board as it features 64Mbit external SDRAM, which is required for uClinux, and missing on other STM32 Discovery boards. You can either get u-boot and (uC)Linux from the company’s github account which contains the required patches, but lacks complete documentation, and a default config file for the kernel for example, or purchase a BSP ($33) with 3-month support, and pre-built u-boot and Linux binaries. There’s also publicly available documentation explaining how to flash the bootloader and the kernel among other things, and links to relevant external resources, without the need to spend any money.

ARM Unveils Cortex-M Prototyping System Based on Altera Cyclone V FPGA

Before micro-controllers or processors are manufactured, simulation is performed in (usually) expensive boards based on FPGA chips from Altera or Xilinx, and once designers have found the system to work as expected, they can move to the next phase and work on the actual silicon. ARM has just released V2M-MPS2 Cortex-M Prototyping System for MCU / SoC / ASIC designers working on Cortex-M processors. Key features: Altera Cyclone V FPGA with ~150K LE 4x 2MB ZBTRAM (32-bit each, with two of them forming a 64-bit memory). ZBT = Zero Bus Latency 16MB PSRAM (16-bit) Touch screen LCD module Range of hardware interfaces – UART, VGA (4 bit per color), SPI, audio (I2S), Ethernet, LEDs, buttons I/O expansion ports (GPIO) FPGA images for Cortex-M processors Example project for Cortex-M0 DesignStart (processor IP has to be licensed separately) USB connection for downloading FPGA images and program image to micro SD card on board […]

Micro Python Brings Python to MCU Boards and Robots (Crowdfunding)

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.
