TI Innovator Hub Connects MSP432 LaunchPad Board to TI Graphing Calculators

January 13th, 2017 3 comments

I remember when I was in high school we all had those TI calculators to cheat enhance our chances of passing exams, but Texas Instruments has now launched what it calls TI-Innovator Hub based on a MSP432 LaunchPad board that connects to some of their graphing calculators and allows student to program and control external hardware through their calculators.

TI-Innovator-HubInnovator Hub hardware specifications:

  • MSP-EXP432P401-ET TI LaunchPad Board
  • 3x input ports, 3x output ports, I²C port
  • Breadboard connector with 20 labeled pins
  • USB
    • Mini USB Port (DATA port for connection to a TI graphing calculator, or a computer running TI-Nspire CX software)
    • Micro-USB port (POWER port to connect to external power source)
  • Misc – Red LED, RGB LED, Light Brightness Sensor, and speaker
  • Enclosure

The hub can then be programmed using TI-84 Plus CE (TI Basic language) or TI-Nspire CX (Lua language) graphing calculators. It’s a bit like playing with Arduino board, but instead of using a computer for programming, you can use a calculator. TI also provides resources to make it easier for teachers. Some extra accessories are also available include I/O Module Pack with sensors and motors, an ultrasonic ranger module, a breadboard pack, and an external battery.

You can watch the “cool box” & “mind blown” video to see what students think about it.

I could not find pricing information. You’ll find a few more details on TI Innovator Hub product page.

M2.COM is a Standard for IoT Sensors Based on M.2 Form Factor

March 25th, 2016 No comments

The IoT ecosystem really feels like a jungle now, not because of a lack of standards, but because everybody thinks about doing their own, so we’ve ended up with a wide range of communication protocols, initiatives, and consortia, and it will take some time until the winners and losers are sorted out. One the of the latest standard is M2.COM platform form factor for sensors that “adopts the standardized M.2 form factor and is defined as an evolutionary module that combines general wireless connectivity with additional built-in computing ability powered by MCU”.

M2.COM_ArchitectureM2.COM architecture diagram above describes both software and hardware requirements, but the specifications themselves only define the form factor, as well as mechanical and electrical characteristics:

  • Consistent with M.2 standard
    • Module size: 22 mm x 30 mm
    • PCB thickness: 0.8 mm ± 10%
    • Pin count: 75 pins
    • Module input voltage: 3.3V DC-in
    • Connector mating force: 30N Maximum
    • Connector current rating: 0.5A / Power contact
    • Connector operation temperature range: -45°C to +85°C
  • Suitable pin definitions for IoT solution
    • USB – A common interface for extending storage
    • SDIO – Another common interface for extending storage through SD/MMC
    • I2C – The most popular interface for sensors. Ex: pressure sensor, temperature sensor, moisture sensor and lightning sensor
    • I2S – Supports audio codec for broadcasting and playing audio through external speakers
    • UART – A commonly used protocol for device control, such as for motor and electric control units
    • GPIO – Basic I/O control, such as indicating lights, alarm and buzzer
    • SPI – Supports LCM to display values collected from the sensor or transmitted by an external device
    • ADC – Common pins of GPIO, the ADC transforms the analog signal from the sensor into a digital signal so that data can be readable and meaningful to the data analyzer

M2.COM_Architecture_2

So the idea is basically to be able to exchange one M2.COM compliant module with another one with better features or a lower cost as needed. You can download the specifications 1.0, design guide, and mechanical information on M2.COM website.

Companies behind the initiative include ARM, Advantech, Bosch, Texas Instruments, and Sensirion. Two products compliant with the standard are currently available: Advantech WISE-1520 M2.COM module and the corresponding WISE-DB1500 carrier board / development board using pico-ITX form factor (100 x 72 mm).

M2COM_module

Advantech M2.COM Module and Carrier Board

WISE-1520 M2.COM module specifications:

  • SoC – Texas Instruments CC3200MOD Cortex-M4 MCU with 256KB RAM, 1MB flash
  • Connectivity – 802.11 b/g/n @ 2.4 GHz up to 16Mbps (UDP)
  • I/O interfaces – 1x 4-wire UART, 1x I2C, 2 GPIOs, 2x PWM, 1x SPI, 2x ADC as per the specs (but no USB)
  • Debug Port – 1x developer and debug port.
  • Power – 3.3V
  • Dimensions – 30 x 22 mm – M.2 type 2230-D3-E form factor
  • Weight – 3 grams

The module runs TI RTOS or ARM mbed OS, and supports multiple IoT communication protocols including LWM2M, OSGI, AllJoyn and MQTT. Software documentation and SDK do not appear to be available publicly.

The development board features a M.2 socket and brings out an SD card slots, expansion headers, a RS-232/422/485 DB9 connector, and a micro USB OTG port, as well as an on-board  humidity & temperature sensor.

Texas Instruments 4K DLP Chip Should Bring Affordable 4K Projectors to the Home, Office and School

January 14th, 2016 4 comments

4K Ultra High Definition (UHD) is slowly with the price of 4K television going down, 4K media players flooding the market starting at $40, and 4K content appearing online via services like Netflix and over the air with DVB-S2. Thanks to the latest Texas Instruments DLP 0.67″ digital micromirror device (DMD), a cost down version of the 1.38″ DMD used in around 80% of cinemas worldwide, we could start seeing affordable 4K projectors in the second half of 2016.

TI_4K_DLPThe chip includes 4 millions tiny mirrors that quickly switch to generate the ~8 millions pixels required by a 3840×2160 display, and should be found in projectors capable of delivering up to 5,000 lumens. The DLP chip can be used in home theaters, but also in the office and at school for presentations or courses were text needs to be easily readable.

The solutions should delivery 100″+ displays with sharp images and text, as well as good color accuracy. Backlight can be achieved with LEDs, lamps, laser, or laser phosphor. Other details have not been published so far, but you can register to be informed once more infor is released on TI 4K DLP page. The new chip should launch in Spring 2016. In the meantime, you can watch an impressive demo with the device filmed at CES 2016.

Texas Instruments claims it will allow affordable 4K projectors, but did not mention any pricing. For reference, Optoma HD141X, a popular 1080p video projector, currently sells for around $550 on Amazon, so I’m assuming an affordable 4K projector could cost between $1,000 and $2,000, possibly in the higher range at the beginning.
