Weightless Development Kits are Finally Available (Sort of)

The first version of the Weightless standard aiming at lowering cost of IoT communications was published in 2013, but so far development kits were nowhere to be found. Nwave has now launched a Weightless-N SDK using sub-GHz spectrum, but not the white space spectrum used by Weightless-W, probably due to regulatory hurdles. Specifications and features of Nwave development board: MCU – Silicon Labs EFM32G210F128 ARM Cortex M3 MCU @ 32 MHz with 128KB flash, 16KB SRAM Connectivity – RM3 radio module (868MHz) and antenna connector (X3) USB – X1 USB port for connection to PC or UART interface, X2 micro USB port Debugging – UART, and 10-pin JTAG connector (X4) Expansion header – 16 through holes for GND, 3.3V, GPIOs, ADC, Timers output, I2C, etc… (X5) Misc – Three Jumpers for UART and other selections (TBD), reset buttons for USB ports?

STM32F746G-DISCO is a $49 Cortex-M7 Board with a 4.3″ LCD Display, Arduino Headers

We’ve already seen Atmel started shipping its SAM V71 Xplained Board based on its latest Cortex M7 a few days ago, but Atmel is not the company which recently introduced a Cortex M7 development kit, as ST Micro also launched an STM32F7 Cortex M7 development kit with Arduino headers and 4.3″ LCD at the end of June. The “Discovery Kit with STM32F746NG MCU” (STM32F746G-DISCO) comes with the following specifications: MCU – STMicro STM32F746NGH6 Cortex M7 MCU with 1 MB Flash, 340 KB RAM, in BGA216 package Memory – 128-Mbit (16 MB) SDRAM (64 Mbits accessible) Storage – 16 MB Quad-SPI Flash memory, and micro SD slot Display – 4.3″ 480×272 color LCD-TFT with capacitive touch screen Camera – Camera connector Connectivity – Ethernet connector compliant with IEEE-802.3-2002 USB USB OTG HS with Micro-AB connectors,  USB OTG FS with Micro-AB connectors USB functions: virtual COM port, mass storage, debug port Audio – SAI audio codec, line IN and OUT jacks, stereo …

Atmel SAM S70 and SAM E70 Cortex M7 MCUs, SAM V71 Xplained Board Are Now Shipping

ARM Introduced Cortex M7 IP in September, and ST Micro simultaneously announced its STM32F7 Cortex M7 MCU clocked up to 200 MHz, and boards are now available, including some running Linux. But two other companies have licenses Cortex M7, Freescale with its Kinetis KV5x micro-controllers which are yet to be mass-produced, and Atmel which has recently announced their SAM S70 and E70 micro-controllers are now in mass production. SAM E70 and S70 have similar features, but E70 offers some extra interface like CAN and Fast Ethernet: ARM Cortex-M7 core running at up to 300MHz (1500 CoreMark) Up to 2MB Flash and 384kByte SRAM Floating point unit (FPU) for high-precision computing and accelerated data processing High-performance internal memory architecture with user configurable Tightly Couples Memories and System memory, and 16kB I and D-cache High Speed USB Host and Device with on-chip high-speed PHY CMOS image sensor interface AES hardware encryption engines, TRNG and SHA-based memory integrity checker Advanced analog front end …

MXCHIP EMW3162 is a $10 Low Power Wi-Fi Module for IoT Applications

You can’t beat ESP8266 Wi-Fi modules on price to add Wi-Fi to your IoT projects, but Hackaday found a new Wi-Fi module by Shanghai MXCHIP Information Technology that sells for $10 on Seeed Studio or Amazon US, that should be better suited to battery operated project thanks to a lower power consumption. EMW3162 also features a more powerful STM32F205 cortex M3 micro-controller, as well as more I/Os than ESP8266. Specifications for EMW3162 Wi-Fi module: MCU – STM32F2 Cortex M3 MCU @ 120 MHz with 128KB RAM, 1MB flashOn Wi-Fi connectivity 802.11b, 802.11g, 802.11n (single stream) on channel 1-14 @ 2.4GHz WEP, WPA/WPA2 PSK/Enterprise (hardware encryption) Transmit power: [email protected]; [email protected]; [email protected] MIN Receiver Sensitivity: -96 dBm Max Data rate: [email protected]; [email protected]; [email protected] HT20 Wi-Fi modes: Station, Soft AP and Wi-Fi direct Advanced 1×1 802.11n features: Full/Half Guard Interval, Frame Aggregation, Space Time Block Coding (STBC), Low Density Parity Check (LDPC) Encoding WPS 2.0, EasyLink Multiple power save modes On-board chip antenna, …

Meet STMicro STM8S Based One Dollar Development Board

ESP8266 modules are $3 Wi-Fi boards targeting IoT applications that can be used in standalone mode, or connected to another MCU based board. But what if you don’t actually need Wi-Fi, but instead require a tiny board to control a few GPIOs? Arduino Pro mini can be used for this, but it costs about $10 on Sparkfun, and it’s certainly cheap enough for most projects. Switching to Aliexpress, you can get Arduino Pro mini clones for about $2, and a bit less in 10 pieces quantities. But you can get even cheaper and add a micro USB port with STMicro STM8S based boards that can be found for 5.5 CNY (Less than $1) on Taobao.com, or – once oversea shipping is factored in – about $1.60 to $1.70 on BuyInCoins, or Aliexpress without headers, and the version with headers sells for about $2 or more. Let’s check the board specifications: MCU – STMicro STM8S103F3P6 8-bit MCU @ 16 MHz, with …

IAR Systems Releases Embedded Workbench for ARM Version 6.40

Earlier today, IAR Systems has announced the release of version 6.40 of Embedded Workbench for ARM. This new version introduces several new features, enhancements and optimizations. The enhancements include a new source browser and text editor, with functionality such as auto-completion, code folding, block selection, block indentation, bracket matching, and zooming. Word/paragraph navigation have also been improved. IAR Systems also enhanced the compiler with improvements to the stack usage analysis functionality that provides calculations of the maximum stack depth for each call graph root and new features such as support for C++ source code and  recursion. A new linker directive check can be used to calculate the stack usage at link time to verify that the used stack space does not exceed the allocated memory. The inline assembler has also been improved and expanded with a large number of new operand constraints and modifiers. In a previous post “Green Hills MULTI 6.0 Compiler Improves ARM MCU Performance by up to …
