    msp430fr2355 serial monitor

    a clarification: - if you use energia : just wire up an async FTDI module to the LP 'backchannel' then use your favourite async sw (putty) - if you use CCS : as above; plus write your own async driver. ccs printf() can be made to send characters to the async port -or- write a 'tiny printf()' - there's a good one somewhere on this forum as I recall (by opossum).

    msp430fr2355 serial monitor

    this is a known problem with the 2355 launchpad emulator section. (FR2433 as well). The output from the emulator to the PC is delayed many seconds in time , OR, comes out quickly when the emulator buffer contains 64 characters. TI will not fix it any time soon. It has been reported on the e2e forum as well. A workaround is to either wait that time for the characters, or write your own async driver, then wire the launchpad async port directly to an off-board module like an FTDI-type. This may be a bit complex if you've never done it before. I wish there were better news, but that's it !!

    MSPflash do not work on MSP4305969

    As I'm just learning about FRAM on Energia -- and referring to the example above: QUESTION --- does count need to be declared persistent ? (or other declared as other type?) cheers,

    Promotion of MSP430FR2433 MCU LaunchPad™ kit

    Yes, the new FR2433 LP is a nice one; and good value-for-money. The I/O is generous and handy. I'm curious why TI configured it's internals the way they did. What is the end-user application(s)? Why the HW 32 bit MPY (yes 32), only a 10 bit ADC, CRC, small FRAM, large SRAM; etcetera. Thoughts?

    Suggestions on MCU/Chip Selection

    Like the old saying goes" "Better never than late".... or was that the other way around ?!?

    NRF25L01 MSP430 to Arduino

    I have used the nRF24L01 Spirilis library both on Energia and CCS; both worked well. I used it point-to-point. My target was '2553. My only wish is that I would have more time to dig into this library and this excellent, low cost nRF further; alas, not to happen soon. cheers,
  8. Hi all, Something called 'Pythagoras Week' means free shipping and a few discounts at the TI Store ... http://www.ti.com/lsds/ti/store/pythagorean-week-august.page?HQS=rtp-tistore-promo-pythagweek17-bitpp-lp-null-wwe
  9. Ah, OK. I see you are not using the SPI however. I don't have a CC3200 - I'll try this on a 2553 / 5529, E17 for interest, this weekend, just to see what happens. I use the SPI / I2C / etc on Energia to quickly try things, so your observation is of interest to me. Maybe someone else on this forum has more experience with your exact configuration....
  10. Which processor are you using? I'm wondering about SRAM memory limitations / buffers breaking. FWIW, I generally use Energia 17 for my non-CCS 6.3 projects; mainly using CCS however. mvg,

    My Stupid Question Space

    Yes, that's the logic analyser. Good price, too. I have 4 of these units attached to various projects / breadboards. And using two laptops the odd time. Cheers.

    Solar power display

    Yep, a great application. May I inquire : are you muxing the LED array one digit -or- one SEGMENT per digit at a time ? Any the 'ON' time ? Just curious how much current the IO pins can supply, it sounds like there's no series limiting resistance, which is perfectly OK. Cheers.

    My Stupid Question Space

    May I recommend that you consider buying a cheap (sub $10), 8-bit, low speed (eg 24 MHz), logic analyser sooner than later ? That, plus experience with the MSP430 'register page' of the CCS IDE 'Debugger' will be good friends to help you sort out the programming of MSP430 family peripherals. Welcome to the forum!
  14. Its definitely possible to program the 2553 / 28 pin device with the Launchpad - especially with CCS. So, likely there's a PCB / wiring issue on your proto. Looking at your schematic.... the capacitor C2 / 0.1 uF -- not needed. Reset needs a +- 30K pullup / 1nF to ground but this may already be provided - depending on where exactly you wired your jumper onto the Launchpad. Can we assume that you've got +3volt / GND connected? Anything else on the schematic we should know about? And I would start with the CCS 'blink' example (toggles P1.0 - often connected to an LED), just to check the communication via Spy By Wire. Keep going - it'll work !!

    I hate it when I forget...

    would those have been rev 1.4 -or- rev 1.5 ? just curious as I have both. Thanks
