  1. Problems with Energia on MSP430 LaunchPad

    There is no problem today to find any IC from any semiconductor company in tiny package. Problem is to find something new in PDIP. MSP430G2553, and other TI MSP devices can be found in TSSOP and QFN package.
  2. Problems with Energia on MSP430 LaunchPad

    We are on Energia topic, so I guess that if you want to use Energia for developement, there is limited number of boards or MSP430 devices with pin mapping, by default supported by Energia (MSP430G2553, MSP430F5529, MSP430FR4133, MSP430FR5739, MSP430FR5969, MSP430FR6989). All FRAM devices are with 20-bit CPU Xv2, same as 5xx/6xx flash family, but they are limited by FRAM wait states. However, it is easier to write to FRAM (same as RAM), than to flash, during runtime. For TI, flash 2xx/5xx/6xx family is finished story, and today they are pushing FRAM family. eZ-FET on G2 LP is limited with not updatable firmware and to some of 2xx SBW target, with 9600 bps USB-UART bridge. New LP's are with updatable eZ-FET Lite on board (open software and hardware) that can program all TI MSP430 SBW devices, 115200 bps USB-UART bridge and Energy trace. I guess that you can develop your project on Energia with G2 LP (that you already have), and than later (if there is need for this) port it to some other device.
  3. Problems with Energia on MSP430 LaunchPad

    I guess that LPM3 with ACLK active should work fine in your case. It takes about 2uA.
  4. An extra USB for MSP430

    MSP430 can be only USB device, not host. For MSP430 USB device, there is open source TI USB dev pack with examples. http://www.ti.com/tool/MSP430USBDEVPACK
  5. Upload firmware code using Energia

    This is device without SBW support, so firmware can be uploaded only by master device that support full JTAG connection (TI MSP-FET or MSP-FET430UIF), not by Launchpads. This device is with UART BSL, but AFAIK Energia (by default) doesn't support this. However, if you are fine with using BSL, than customized command line for flashing, for TI BSL_Scripter can be inserted inside Energia, and firmware can be uploaded by IDE button. I explained similar thing here... https://forum.43oh.com/topic/9337-where-do-i-find-the-script-that-runs-after-clicking-upload/
  6. Unfortunately, this things must be analyzed with scope and on board modification until (almost) perfect signal shape is found. https://electronics.stackexchange.com/questions/33372/spi-bus-termination-considerations
  7. No, 5529 is not 16-bit device. It is with CPUvX2 that have 20-bit registers and 20-bit assembler instructions. Some of this instructions (so called address instructions) can be executed in one cycle. BTW, also, all FRAM devices are with 20-bit registers and 20-bit assembler instructions.
  8. Problems with Energia on MSP430 LaunchPad

    Maybe this f432 is somehow related to MSP432? Because I can find any VID / PID in Energia (boards.txt file) related to MSP-EXP430F5529LP, MSP-EXP430FR4133LP, MSP-EXP430FR5969LP, MSP-EXP430FR6989LP, MSP-EXP430G2553LP or MSP-EXP430FR5739LP and identical to this numbers (0451, f432). Edit: I was wrong, it is not related to MSP432. Solution is here... https://e2e.ti.com/support/microcontrollers/msp430/f/166/t/539487
  9. RFC: CNC BoosterPack

    I put IC's on the board center position without breaking (too much) ground layer with other lines. Better heating dispersion and easier connection / layout with other components.
  10. MSP430F5529 USB HID Example for Energia

    There is C open source TI USB stack with examples (with one that you need is included)... http://software-dl.ti.com/msp430/msp430_public_sw/mcu/msp430/MSP430_USB_Developers_Package/latest/index_FDS.html Supported by CCS or IAR, not Energia.
  11. MSP432E4

    I already commented here... http://forum.43oh.com/topic/10502-msp432p4111-what-do-we-know-about-it-so-far/?do=findComment&comment=78452 that don't see link with MSP430 family anymore.
  12. MSP432P4111: What do we know about it so far?

    MSP432P401/4111 is without USB, with 1.6 - 3.7V VCC range, similar to MSP430. MSP432E is with USB, but VCC is 3 - 3.6V, nothing for me here. EDIT: Also noticed that 432P401/4111 still have ports (some with mapping option) similar to MSP430, 432E don't.
  13. Does Energia support JTAG?

    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.
  14. Does Energia support JTAG?

    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.
  15. Does Energia support JTAG?

    There is low-cost (14$) FR2311 LP with open (software / hardware) source and updatable eZ-FET Lite on board, with FR2311 as target. However, on-board eZ-FET Lite can program / debug also other off-board devices, by SBW, with removed jumpers between LP master and target section. http://www.ti.com/tool/MSP-EXP430FR2311 If you don't want LP (because of some special reason), and to use a TI FET, that is not supported inside Energia, there is CLI tool MSP430-Flasher that can be called by Energia (on any OS), for downloading firmware. It is up to date and and support all TI tools. http://www.ti.com/tool/MSP430-Flasher I done this for my flasher without any problems, and MSP430-Flasher can be integrated on the similar way. http://forum.43oh.com/topic/9337-where-do-i-find-the-script-that-runs-after-clicking-upload/ However, I don't know if your device (FR2311) is by default supported in Energia. This is not related to downloading firmware, that should work just fine.
