    bluehash got a reaction from chicken in Forum flooded with spam   
    Hi All,
    I cleaned up the site last week. This year has not been the greatest for me(and for alot). Pardon the neglect. True that the blog has not been update, but I have not seen much content on the MSP430/432. Also TI's E2E has been vastly popular.
    There was no "commercial" side. I still pay for server and forum licenses out of pocket.
    I've kept it up since there is alot of useful info and people benefit from it.

    And with J7 removed, everything works just fine. Note to the future: if trying to do I2C on EXP430G2ET, remove J7. It probably says that somewhere in the user guide.

    bluehash reacted to Norwoodd in Web Controlled Outlets: Using an MSP430 to Remotely Control Wireless Outlets   
    The goal of this project is to utilize an MSP430 to allow existing remote-controlled outlets to by controlled over Wi-Fi. As purchased, the outlets can be controlled with a provided remote control which uses 434 MHz radio signals. By programing the MSP430 to replicate the signals from this remote and hosting a web page with controls on the MSP430, the outlets can be able to be controlled from anywhere on the same Wi-Fi network. The completed project provides a web page that can both control each of three outlets individually or all three at once. This is done using an MSP430 as a controller with a 434MHz transmitter sending commands to the outlets, and an ESP 8266 Wi-Fi module connecting to the network. A schematic of the completed project is shown in Fig. 1, and a photo of the completed project is shown in Fig. 2. With this set up the outlets can be reliably controlled from anywhere on the same Wi-Fi network.  The components required for this project, along with the equipment necessary are listed below. All the components can be purchased for less than $30.
    I was able to write an interface to control the outlets, as well as serve a webpage to control the outlets. This was the final project for my Embedded Systems class at John Brown University. more details are avalible in the attached file.

    To follow up with @Rei Vilo the actual errors are important here, as is the processor (though I would presume G2553 given where you put the question).  Also, the interface module you are trying to use (I2C I would hope, since the MMA8452Q only communicates with I2C), what header files you included, what processor you selected in CCS project setup, and so on.

    bluehash reacted to Peabody in Using a CP2102 with BSL-Scripter   
    I don't know if this has any application for Energia, but might be of use to someone at some point.
    I've been working on a way to embed a generic USB-to-UART adapter like the CP2102, FT232 or CH340 in an MSP340 project so firmware can be updated without having to buy a Launchpad.  The newer MSP430 parts presented a problem because BSL-Scripter, TI's software for BSL flashing for those parts, doesn't transmit the special invoke pattern on /Reset and Test.  Instead, it just brings both lines low, which messes things up.
    I gave up on trying to recompile Scripter, but I've written a Windows program that generates the pattern, and developed  methods to disconnect DTR from /Reset after the pattern has invoked BSL, but before BSL-Scripter is run, which allows flashing to proceed with /Reset high.  A full explanation, source code, executable, and schematic are in my Github repo.  It all seems to work, at least with an FR2311 under Windows 7.

    bluehash reacted to mph in Sensirion SHTC3 temperature-humidity sensor   
    Sensirion has recently introduced an inexpensive, low-power temperature humidity sensor SHTC3 designed for operation in the range 1.62--3.6V .  It should be a useful peripheral for MSP430 battery-powered applications.  I have tested 3 sensors with the F5529 Launchpad and they exhibit reliable, consistent behavior.  For reference, I have written some demo code for I2C communication that is available on github:
    https://github.com/microphonon/SHTC3
    The SHTC3 comes in a small DFN package, so to do breadboard testing I had to build my own breakout boards and use reflow soldering (see photo).

    You can combine the LaunchPad with LCD with a second LCD. 
    The MSP-EXP430FR4133 with LCD goes for USD14 while the MSP-EXP430FR2433 is USD10.
    The larger MSP-EXP430FR6989 with LCD is USD18 vs. USD16 for the MSP-EXP430FR5969.
    If power consumption is critical, why not consider an e-ink screen? Pervasive Displays have a wide range of displays, B&W and also tri-colours with red. All are supported with an Energia library.

    At this state, we need to know more about your project.
    And no need to double post your question at Which MSP430 to pick? Advice please. This is against netiquette: see Netiquette for Newbies.

    I've had intermittent problems with various versions of CCS and Energia in the past.  After seeing your post I updated my CCS to 7.4.0.00015 with no issues.  However, based on your reported error message, it's worth taking a moment to go to Window->Preferences->Code Composer Studio->Products to see if Energia is still installed.
