TI Releases TI-RTOS, a Free Real Time Operating System for MCUs

Texas Instruments announced TI-RTOS, a complete real-time operating system based on a preemptive multithreading kernel for its MCU platforms. TI-RTOSs includes SYS/BIOS real-time kernel and network developer kit (NDK) TCP/IP stack. TI expects this new OS to speed-up software development by eliminating the need to write complex system software such as schedulers, protocol stacks, and low-level drivers. TI-RTOS features and benefits: Complete embedded operating environmentthat provides full middleware and drivers including: Deterministic, real-time multitasking kernel (SYS/BIOS) TCP/IP stack, including network applications USB, EMAC, MMC/SD host and device stacks and class drivers FAT-compatible file system fully integrated with C RTS file I/O functions Ethernet, USB, UART, I2C and SD device drivers Low overhead core-to-core communication mechanism for dual-core devices Ability to move functions between dual core devices to optimize performance by using the same TI-RTOS kernel on both the ARM and C28x DSP cores. Documentation and examples to augment designs, including examples and […]

smARtDUINO Open System Provides a Low Cost Modular Arduino Platform

smARtDUINO is a new platform design by the former ARDUINO’s manufacturer (Update: This claim appears to be incorrect and a lie) composed of several compact modules and is a fully funded project on Kickstarter (Less than 3 days remain to become a sponsor). The platform is not based on a single processor, architecture or language but, makes use of an universal platform that can be used to connect components originally developed from different companies, technologies and form factors. For example, it is possible to integrate modules, accessories or shields from Arduino, Netduino, ChipKit and even interact with smartphone using an ADK module, without having to use a breadboard and/or soldering. Interoperability is made possible thanks to what they call “smARtBUS Open I/O“, which is a standard for connectors designed after looking at existing (Arduino) platforms on the market. The company opted for 2 solutions composed of 2 connectors: smARtBUS BASIC […]

FRAM (Ferroelectric Random Access Memory) and Texas Instruments MSP430FR57xx MCUs

I’ve recently received a complementary book entitled “Texas Instruments FRAM MCUs for DUMMIES” sent by Mouser, that provides technical and practical information about FRAM (Ferroelectric Random Access Memory) – pronounced F-RAM – and Texas Instruments MSP430FR57xx MCU series which makes use of this relatively new type of memory. FRAM is a non-volatile memory with power and write speed & endurance characteristics that almost matches SRAM capabilities, and leave traditional Flash and EEPROM memory in the dust in terms of performance, as you can see from the table and diagram below. At constant speed, FRAM consumes 250x less than Flash/EEPROM. Please note the FRAM write speed also depends on the MCU used, and a MCU @ 8MHz can write the FRAM @ 1400 kBps (Source: TI). However, you won’t see this type of memory in devices like smartphones anytime soon because the maximum size currently manufactured is 1MB, density is higher […]

$25 Outbreak Galago – Cortex M3 Open Hardware Development Kit

Outbreak Galago is a tiny development kit based on a Cortex M3 processor that fits a debugger, and is destined for rapid electronics prototyping. The company promotes it as some sort of Arduino board on steroid (MCU wise) and sells for $25 on kickstarter, and less than $10 in 10k quantities. Here are the board specifications: 72 MHz 32-bit ARM CPU with 32KB of flash ROM and 8KB of RAM (NXP LPC1313 TBC) Integrated hardware debugger One high-speed SPI port, up to 36 Mbps One high-speed I2C port, up to 1.5 Mbps One UART/USART with hardware flow-control capability, up to 256 kbps 10 high-speed PWM pins, 6 driven by 32-bit (high-resolution) timers 6 ADC (analog) input pins with 10-bit resolution at over 400 KSa/sec 25 GPIO (digital) input/output pins The form factor and built-in debugger (via USB) are not really new, as those are already featured in devkit such as TI Piccolo controlSTICK, […]

16 Euros Arduino Leonardo Board is Now Available

Arduino Leonardo is a new Arduino board with a 16 MHz Atmega32U4, 2.5KB RAM, 32 KB of Flash memory, 20 digital I/O, 12 analog inputs and 7 PWM outputs. In this version the MCU takes care of USB communication with the host, whereas for Arduino Uno, a separate chip is required to take care of this, which makes Arduino Leonardo cheaper than Uno. Here’s a summary of Arduino Leonardo specifications: Microcontroller – Atmel ATmega32u4 @ 16 MHz SRAM – 2.5 KB onchip (ATmega32u4) Flash Memory – 32 KB onchip (ATmega32u4) of which 4 KB used by bootloader EEPROM – 1 KB onchip (ATmega32u4) Operating Voltage – 5V Input Voltage – (recommended) 7-12V | (limits) 6-20V Digital I/O – 20 pins PWM – 7 channels Analog Input – 12 channels DC Current per I/O Pin – 40 mA DC Current for 3.3V Pin – 50 mA Watch the video to get […]
