Texas Instruments has launched the MSP-432, a Cortex-M-based microcontroller that aims at providing developers with a higher-performance upgrade path for MSP-430 users while still retaining low-power operation. The 32-bit processor uses an M4F core with FPU and DSP extensions, achieving a CoreMark score of 3.41/MHz and a certified ULPBench score of 167.4, among the highest in its performance class.

The device can operate at full speed down to a supply of 1.62V, simplifying direct sensor interface. It specs an operating current of 95 µA/MHz and a sleep mode current of 850 nA with its real-time clock running. The device also contains a number of architectural features that support reduced power consumption while boosting performance.

mbugs™ – the building blocks of an integrated ecosystem for the mbed online IDE that enables form-factor electronics prototyping.

The mbug ecosystem uses the mbed online compiler and SDK where you can quickly create embedded applications that are easily downloaded onto the mbug processor through a standard USB interface, just like adding a file to a USB flash drive.

In addition to the processor mbugs which run the applications, we’re offering a number of expansion mbugs that can be stacked onto the processor to create multifunctional systems. Together, you can use mbugs to build projects containing sensors, displays, relays, and servo motors.

Node-RED is a visual programming interface for the Internet of things. It doesn’t require coding experience, making it easy to connect your physical things to the cloud.

Node-RED is based on Node.js. The Node-RED application runs as a web server, and you customize and manipulate functional “flows” from any computer’s browser, local or remote. The server application can run on an inexpensive device like the Raspberry Pi.

In this project you’re going to create a simple HTTP client with an ESP8266 WiFi module. Having your ESP8266 connected to your network, it requests the current Bitcoin price. This is an example on how to retrieve data from the web.

First, flash your ESP8266 module with NodeMCU

NodeMCU is a firmware that allows you to program the ESP8266 modules with LUA script. And you’ll find it very similar to the way you program your Arduino. With just a few lines of code you can establish a WiFi connection, control the ESP8266 GPIOs, turning your ESP8266 into a web server and a lot more.

Figure 1 illustrates a digitally programmable precision resistance that can serve as a microprocessor-driven power-supply load in custom-designed ATE (automatic-test equipment). An 8-bit current-output DAC, IC1, a DAC08, drives current-to-voltage converter IC2A, which in turn drives the gate of power MOSFET Q1. The device under test connects to J1 and J2. In operation, current from the device under test develops a voltage across sampling resistors R8A and R8B.

In the past few months ESP8266 has created a real revolution in the IoT space. I’m using it in a project that will hit Indiegogo in a month or so and you, of course will support me ☺ During the development process I’ve learned a lot and I want to share a part of it. Let’s build cheap open WiFi finder together!

Extremely cheap low-speed PC/USB oscilloscope with STM32 (STM32F042) microcontroller.

Announced in January 2014 Cortex-M0 microcontroller family that features crystal-less USB FS device allows to cut noticeable part of BOM when building oscilloscope/recorder similar to miniscope v2c/v2d. STM32F042F devices are interesting in particular because of small and friendly TSSOP20 package with minimum number or power lines.

STM32F042F4 devices feature USB bootloader (DFU), single 1MSps ADC (so single channel sampling would be preferred to avoid crosstalk issues), 16 kB FLASH memory (~2 times more than needed) and 6 kB RAM.
