    jazz reacted to Peabody in Modified BSL-Scripter for Windows now works with FTDI and other USB-to-UART adapters   
    A new WIN32 version of BSL-Scripter.exe has been compiled which allows BSL flashing using generic USB-to-UART adapters such as the FT232, CP2102 and CH430 as the hardware interface.  It can be used with MSP430 F5xx F6xx, and FRxx parts with UART BSL.
    This version has a new MODE line option "INVOKE", which causes Scripter to directly generate the BSL hardware invocation sequence on the adapter's DTR and RTS outputs, which in turn are connected to the /Reset and Test pins on the target device.  It produces the pattern shown in Figure 2 of slau319w.pdf and slau550s.pdf, which is normally generated by the Rocket or MSP-FET.  If the INVOKE option is used, you must include the PARITY option as well.
    I have successfully tested the new Scripter on an MSP430FR2311 using all three adapter types.  It would be helpful if others could test other relevant MSP430 parts and report the results.
    This has finally come about as a result of the generous efforts nagaokanchi, also known as "drcrane" on Github, who not only got TI's source code to compile with new versions of all the dependencies, but also navigated the mysteries of BOOST to control the DTR and RTS lines.  The new Scripter and a related Instructions file are contained in "BSL-Scripter-v3.4.1.zip" in the Releases folder of his repository, which also contains the source code:
    https://github.com/drcrane/bslscripter-vs2017/releases
    For those who must run an official TI version of Scripter, I will leave on my Github the now-deprecated kludge option for using these adapters with the official Scripter, but of course it requires either manual intervention or an additional circuit:
    https://github.com/gbhug5a/CP2102-with-BSL-Scripter-for-MSP430
    And finally, a reminder that the older MSP430 parts which use BSLDEMO2 for flashing, including the F1xx, F2xx, F4xx, and G2xx parts with BSL, can also be flashed with these adapters if a modified version of BSLDEMO is used, such as the "BSLDEMO-2.01C.exe" found in my other repo:
    https://github.com/gbhug5a/MSP430-BSL
    Texas Instruments has neither reviewed nor approved any of this. But I continue to hope TI will officially make similar changes to BSL-Scripter and BSLDEMO to support the use of these generic adapters.

    jazz reacted to Peabody in Multiplexing 7-segment displays by segment   
    In case it might be of use to someone, I've posted a Youtube video and created a Github repo dealing with an alternate way of multiplexing 7-segment displays that has a greatly reduced parts count.  It's multiplexing by segment instead of by digit.  The video shows this method implemented with an MSP430G2553.  The Github repo has demonstration Arduino Nano sketches, but they should work as-is with Energia except for the pin assignments.  The video is on my local OSH group's channel, and I can't respond to comments there, but will answer questions here if there are any.

    jazz reacted to Peabody in BSL for G2553 and G2231 using embedded USB-Serial adapter   
    I originally posted about this in October, but wanted to report that I've updated the G2553 special BSL entry code to fix a bug.  Everything is included in my Github repository:
    https://github.com/gbhug5a/MSP430-BSL
    To review,  this project deals with the MSP430G Value Line processors, and was prompted by the idea of embedding a CP2102 USB-to-Serial adapter in a project's circuit rather than hooking one up through a pin header, or using the Launchpad for JTAG flashing.  So all you would need to flash new firmware is a USB cable and the right software.  A detailed description of what's involved is in the long-winded PDF file.  The PDF deals with the much-despised BSL password in the G2553 ROM-based BSL, and offers a couple ways around it, including special boot code that fits entirely in the INFOA segment along with the existing calibration data, and lets you run BSL with INFOA protected from erasure, which means you can flash new firmware without knowing the password, and without erasing the calibration data.

    There's also a complete custom BSL system for the lowly G2231, which has no built-in BSL.  Included are installers for the chip and the PC software to drive the process.  And there's a discussion of circuit design for using embedded adapters or modules containing them.

    The installers for the chips use the Naken assembler, and the PC software uses the LCC compiler.  But the repo includes both the source code and the executables for everything, so assembler-phobes can just flash the hex files.

    There are two small bonuses - a VBScript for Windows that converts an IntelHex file to TI-TXT format, and as part of the BSL installation for the G2231, the calibration values for 8, 12 and 16 MHz are derived from the existing 1 MHz calibration value, with no crystal required, and saved in the usual places in INFOA (based on original work by Steve Gibson).

    I did the original work on this for a project, and decided I might as well write it up in case it might be useful to others at some point.  The Value Line processors are kinda old school now, but are still available in DIP, and are still pretty popular.  And the circuit design portion may be more generally useful.

    Of course I'd like to know about any bugs or errors anyone may find.  Hope this will be useful.

    You just need to edit configuration (text) files, and then Energia will call external CLI application (MSP430-Flasher) for downloading code. Interface between TI FET an target device will be handled by MSP430-Flasher that will automatically detect connected FET, not by Energia anymore. Downloading code will be done by upload button on original / unmodified Interface, simple as it is. It is all explained here, but instead my flasher, command line parameters for MSP430-Flasher should be used.

    AFAIK, any LP is with virtual com port, that is not needed by Energia. I didn't noticed any Energia popup with something like "missing virtual com port", when there was no virtual com port available. As I allready noted, I don't see any problems related to downloading code by SBW with MSP430-Flasher by any LP. Problem is in missing Energia header / library files for unsupported devices.

    Last summer I worked on the idea of embedding a USB-to-Serial adapter in Value Line projects so firmware revisions could be done with only a USB cable and the right software, without needing a Launchpad.  The adapter chips and modules containing them are now so inexpensive that this makes sense.  On the chance that it might be useful to someone, I've written it all up and posted it to Github:

    The project is summarized in the README, and explained in detail, with needed software and hardware, in the PDF.

    TI is working right now on hardware revision of MSP-FET, so if you want to buy one, be sure that this one is with new hardware revision.
    For low cost entry to MSP430 world, my advice is always for MSP430F5529 LP with updatable and open software / hardware design. Never for old and slow, closed and not updatable G2 LP (or any other board version with integrated this old FET).

    Weekend-project:
    Autoranging microvoltmeter based on the MSP430FR4133 launchpad.
    ADC used: MIcrochip MCP3422, an 18bit, 3.75 sample/second Sigma Delta with 2 differential inputs. I2C interface
    This nice little chip contains a programmable amplifier (x2,x4,x8) and a not-too-bad internal reference of 2.048V.
    Max input range is +/-2.048V, resolution (8x amplified) is 2uV.
     
    Hand-etched a single layer PCB which goes on top of Launchpad.
     
     

    Type K cable in hot water: 2.93mV, 73Kelvin temp difference to ambient
     
     

    compare with my Fluke 289, 0.06% (datasheet says 0.05% typical, 0.35% max)
    Not too shabby for a chip that costs 3 bucks.
     
     

    Current consumption: on average <40uA, the whole setup would run 5000hours from a CR2032
    The ADC does 1 sample/second and sleeps the rest of the time, the MSP430 does what it likes the most: sleep in LPM3
