Microchip Unveils 2 Arduino Compatible Boards, and a Prototype-Friendly PIC32 MCU

Microchip Technology has announced several new tools, expanding its Arduino compatible chipKIT platform ecosystem, based on Microchip’s 32-bit PIC32 microcontrollers (MCUs) available in low pin count SOIC or SPDIP packages. Digilent’s chipKIT DP32 board features basic I/O and interface components, including a prototyping aera, user buttons, and a potentiometer. The board (part # TDGL019) costs $23.9, and should be available on May 17 at microchipDIRECT. The chipKIT Fubarino Mini board, from a partnership between FUBAR Labs and Schmalz Haus, provides another option for Arduino-compatible development with 32-bit PIC32 MCUs, using a smaller form factor. The board is supposed to be available today for $19.95 on microchipDIRECT, but I could not find it yet. If you don’t want/need a development board, the company also provides PIC32MX250F128B MCU in PDIP package (28-pin) preprogrammed with chipKIT USB Bootloader. This MCU, clocked up to 40Mhz, includes 128 KB Flash and 32 KB RAM, as well […]

Energy Micro Launches EFM32 Wonder Gecko Cortex M4 MCUs and Starter Kit

After having announced EFM32 Wonder Gecko MCU family in February, Energy Micro has just officially launched their new family of high performance, low power MCUs. These micro-controllers come with an ARM Cortex-M4 CPU with floating-point unit (FPU) and DSP instruction set that helps reduce the processing time of your application in active mode. All MCUs come with 32KB SRAM, and between 64 to 256KB flash. Energy Micro expects their new chips to be used in applications such as gas metering, energy metering, water metering, smart metering, alarm and security systems, health and fitness applications, and industrial and home automation. One key advantage of this new MCU family is the implementation of TSMC’s eLL (Extreme Low Leakage) technology that dramatically reduces power consumption at high temperatures. There top of range MCUs (EFM32WG995FXXX) feature the following specifications: ARM Cortex-M4 CPU platform @ up to 48 MHz with DSP instruction support and floating-point […]

Texas Instruments Announces Tiva Cortex M4 MCUs and $12.99 LaunchPad Evaluation Kit

Texas Instruments has just announced the Tiva ARM MCU platform, and specifically the Tiva C Series TM4C123x ARM Cortex-M4 MCUs, which are the first Cortex-M MCUs to be built on 65 nanometer flash process technology. The Tiva C Series TM4C123x MCUs, formerly known as Stellaris LM4F MCUs, are available now and target home, building and industrial automation. Key features and benefits of Tiva C Series MCUs: MCU Core – ARM Cortex-M4 floating-point core, operating at up to 80 MHz. Mixed-signal applications with high-performance analog integration – 2×12-bit ADC and 3 comparators.12-bit ADC accuracy is achievable at the full 1 MSPS rating without any hardware averaging. On-chip connectivity options – USB (host, device and On-The-Go), UARTs, I2C, SSI/SPI, CAN, etc.. Non-volatile storage of user interface or configuration parameters to reduce system cost – Thanks to integrated EEPROM. Low power – Standby currents as low as 1.6 uA. Large choice of MCU […]

Keil RTX RTOS is Now Available for Energy Micro EFM32 MCUs

Energy Micro has recently announced the availability of the Keil RTX real-time operating system (RTOS) as part of its Simplicity Studio tool suite. The Keil RTX has been optimized for ARM Cortex-M processors to provide flexible scheduling and high-speed operation, and has been improved to enable an ultra-low power, deep-sleep mode between tasks. Energy Micro has implemented a tickless mode in Keil RTX. This mode allows the EFM32 Cortex M3 MCUs to wake up only when needed, either at a scheduled time or on an interrupt event. This results in much lower power consumption in sleep mode compared to other SysTick implementations. The video below shows the difference between SYSTICK mode where the system consumes about 2.7mA in active mode, and 830 uA in sleep mode to the new tickless mode where the MCU still consume the same amount of energy in Active mode, but only 1uA in sleep mode, […]

Thingsquare Mist – Open Source Firmware for The Internet of Things

Thingsquare recently released the source code for the Thingsquare Mist firmware, an ultra lightweight router software (<4 kB memory) for the Internet of Things based on open Internet standards such as IPv6, RPL (Routing Protocol for Lossy networks), and 6lowpan. Thingsquare Mist allows to connect battery-powered wireless micro-controllers to the Internet, and is currently used in applications such as smart light bulbs, connected home appliances, and connected cities. The IPv6 mesh network is composted of nodes with a low power radio that communicate with the Mist router (Green), which in turn connect to the Internet and Thingsquare Cloud backend (Thingsquare Haven) to store the data, and/or receive control commands via Ethernet or Wi-Fi. The end users can then use an App to monitor, and/or control the devices remotely. Thingsquare Mist uses IETF RPL IPv6 mesh routing protocol (pronounced “ripple”) for IPv6 nodes communications. Thingsquare Mist runs on several low-power wireless […]
