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.

Texas Instruments Announces Ultra-Low Power MSP430 “Wolverine” MCU Series

February 29th, 2012 No comments

TI Ultra-Low Power MCUs Texas Instruments announced a new series of its MSP430 MCUs codenamed “Wolverine” for its aggressive power-saving technology. The company claims this ultra-low-power MSP430 microcontroller platform offers at least 50 percent less power consumption than any other micro-controller in the industry with 360 nA RTC mode and less than 100 µA/MHz active power consumption.

Since typical battery powered applications spend as much as 99.9 percent of their time in standby mode, Wolverine MCUs power consumption of 360 nA in standby mode would more than double the battery life.

Here are the key power savings techniques and technology using the the Wolverine MCU (MSP430FR58xx):

  • Ultra low leakage (ULL) process technology. TI developed ULL technology that offers a 10x improvement in leakage and optimized mixed signal capabilities. Power reduction are also achieved thanks to an improved 130 nm process technology and more than 30 power-optimized analog and digital components.
  • Unified FRAM (Ferroelectric Random Access Memory). Taking advantage of FRAM  low power memory, “Wolverine”-based MCUs can operate at less than 100 µA/MHz in active mode and consume 250x less energy per bit compared to Flash- and EEPROM-based microcontrollers. In addition, FRAM is 100 percent non-volatile, which gives developers the low power, speed and flexibility of SRAM while retaining the key no-power storage capability of Flash
  • MSP430 ultra-low-power system legacy, peripherals and software for easy development. The new platform takes advantages of exiting MSP430 features as well as TI’s  MSP430Ware software and resource package, and low-power code optimization software tools.

Comparison of battery life based on IC

Battery Life Comparison: CPU vs MPU vs MCU vs Wolverine Platform


Battery powered devices usually have a lifetime of 10 years, with Wolverine technology this would be extended to 20 years. Such low power MCU may also enable devices powered by energy harvesting where you never need to replace the battery. With this technology, Texas Instruments envisions low power devices such as a device worn on your finger that allows intuitive, touch-free interaction with the digital world. or a solar panel the size of a microcontroller that enables environmental intelligence in any building or a smoke detector with carbon monoxide sensing, thermostat control and biometric security capabilities without increasing its size.

You can watch the video introduction of Texas Instruments’s Wolverine platform.

The “Wolverine” MSP430FR58xx microcontrollers will be available for sampling in June 2012. However TI says that developers can get started with existing MSP430 solutions.

You can find more information on TI Wolverine page as well as on this Wolverine Platform PDF Presentation.

    USB is widely deployed in embedded devices of all kinds, resulting in simple interconnectivity and interoperability. This simplicity comes at a cost: the internal functions of USB are quite complex. This is of no consequence to the user of a USB-enabled device, but the embedded software developer does need some understanding of USB internals. Even if a commercial USB stack is employed, an appreciation of how it works enables it to be used optimally. In this session, the history and internal operation of USB will be reprised in detail. Then, the changes and enhancements that come along with USB 3 will be reviewed.
  • Beagleboard 101 ( Wednesday 8:00- 9:15) by Jason Kridner (Software Architect and Community Develop, Texas Instruments)
     Learn or refresh yourself on the basics of running Linux on the BeagleBoard, how to engage the BeagleBoard community, detail the boot process and survey the available community and commercial software that might be of greatest interest.  A short update on the Linaro and Yocto Project community oriented organizations will be given and everyone will make sure they can boot and navigate the software installed on the provided boards.
  • Embedded IPv6 Ready or Not, Here it Comes (Wednesday 8:00- 9:15) by Thomas Cantrell (Engineering Mgr, Networking, Green Hills Software) and Dave Kleidermacher (CTO, Green Hills Software)
     Embedded systems, such as home appliances and automobile electronics, are becoming new members of the Internet of Things adding features such as field upgrade, remote management, and application downloads. The growth of these new devices adding further pressure to the nearly exhausted IPv4 address space. In addition, new US Government initiatives are increasing the interest in IPv6 network connectivity not only in the government and the carrier market, but also even now in the enterprise and the home. Enterprise customers are increasingly demanding support for IPv6 from their vendors. This class starts by talking about the technical details of IPv6 in relation to traditional IPv4 networking. It talks about new requirements and standards. It then goes to explore how to add and support IPv6 at a system level and then at an application level. Finally, it offers suggestions on how to become more oriented with IPv6 networks.
  • Linux LCD Integration with the BeagleBoardToys ULCD-Lite ( Wednesday 14:00- 15:15)
    Learn how to interface a system-on-a-chip running Linux to an LCD panel by deriving new panel drivers from existing panel drivers.  The basics will be explained with the existing ULCD-Lite integration and some topics regarding system integration will be covered.  Students will be able to extend their Linux kernel driver to support additional display timings and modes.
  • More Embedded Linux Jumpstart (Wednesday 14:00- 16:45) by  William Gatliff (Consultant, Freelance).

  • Embedded Android Workshop (Thursday 8:00-12:15) by Karim Yaghmour (CEO, Opersys Inc.)
    Part of the Android Certificate Program. Bring a notebook with a minimum of 3 MB of memory and at least one of the following CPUs Intel Core2 Duo, Core i5, or Core i7 2.5 GHz or higher OR AMD Phenom or Phenom II.
  • Best Practices in Designing Low Power Embedded Systems (Thursday 9:30-10:45) by Bhanu Kapoor (Consultant, Mimasic)
    We focus on the power management architecture verification experiences of Wireless SoCs and specifically focus on the tasks for validating a power managed ARM Cortex A-8 core used in SoCs targeted for mobile segment. Power techniques used on the chip include clock gating, voltage scaling, and power gating. We focus on the verification challenges faced in designing the processor core including RTL modeling of power switches, isolation, and level-shifting cells, simulation of voltage ramps, and generation of appropriate control signals to put the device into various power states.
  • Device Drivers Demystified (Thursday 9:30-12:15) by Doug Abbott (Firmware/Software Engineer, Intellimetrix)
    Application programmers often view device drivers as some sort of black magic. All that bowing and scraping to the operating system. The objective of this class is to make the case that drivers really aren’t that mysterious.So what is a device driver? Fundamentally, it’s just a mechanism to abstract out the often messy details of hardware devices and present a uniform set of APIs to the application programmer, who can then deal with the device as a simple source and/or sink of data. We’ll develop an abstract model of a device driver independent of any specific operating system. We’ll explore issues such as: how the driver connects with the rest of the system, how to identify and connect to a specific device, what happens if the device has no data or can’t accept data.Then we’ll go on to look at how Linux treats device drivers.
