  1. @Aunullah I can't help with the Wifi portion of your question, but last year I was able to plug-in the TinyGPS++ library to work with an Adafruit Ultimate GPS unit (currently out of stock) and an MSP430F5529. I was only interested in capturing current location on an hourly basis for a backpacking trip, but the Tiny GPS library was pretty easy to work with. Bob
  2. @BinaryA , This is from the user docs: "The jumper J5 VCC also must be opened if the LaunchPad development kit is powered with an external power supply over J6 Table 1 or the eZ430 interface J4." Take look at: slau318.pdf (I'd provide a direct link but my holiday park wifi seems a bit challened here in Australia) HTH, Bob
  3. FWIW, I still find myself referring back to sections in MSP430 Microcontroller Basics. One of the benefits I find working with the MSP430 line is the general code compatibility across many of the devices. I also make extensive use of the code examples available in the MSP430Ware toolset. Often those examples provide a reasonable starting point when working with the different peripherals or devices. One of the real benefits with the '430 line is power management. With that in mind, take a look at the code examples using the interrupt (ISR) models rather than polling. An example of such would be msp430g2xx3_P1_02.c Which would be useful for a pushbutton activated LED. FWIW, you'll find good code analogs for the Davies book examples in the MSP430Ware peripheral examples. Have fun, Bob
  4. Are you referring to the Sparkfun GPS Logger Shield? If so, double check pinouts; they will not be the same for the '5529 I've been running TinyGPS++ with an msp430F5529 connected to an adafruit ultimate GPS breakout board without problem for the last year. And, don't forget that the Tx from the GPS goes to the Rx for the '5529... Easy to cross-up.
  5. I stand corrected. I was not thinking in terms of I/O but Vcc. Unclear communication on my part.
  6. > Also, I'd like to get a MSP-FET while it's on sale, do you have any thoughts on the device? I have a pair of the older FET-430UIF devices and one of the new FETs that allows power consumption evaluation. The two things they all share in common: 1) 14-pin JTAG interface (you can jumper to the LP devices, but they lack the JTAG connectors), and they are $100+ devices. That being said, I have at times liked being able to separate the programming access and the USB port when working with the F5529. Whether they are worth the expense is going to be a personal determination.
  7. @makiyang614 Glad to see your level of excitement. I've used the F2013 extensively, and have also worked with the FG4618. You won't find launchpads version for either of these devices, though you can find the eZ430-F2013, which preceeded the launchpads as an inexpensive introductory development tool. The FG4618 was/is intended to be a one-stop LCD driver chip, with multiple peripherals to allow interaction with the "real world." The F2013 has significantly less capability, but it does feature a 16-bit SigmaDelta ADC (you'll find some inexpensive IR motion detector projects built around this chip). I agree with @Rei Vilo regarding the F5529 launchpad - it's very versatile, and includes a built-in USB capability. I suspect the first major difference you'll see between the Arduino and the '430 is the interrupt-driven approach used to attain very low power requirements. (Oh, almost forgot, the '430 is NOT 5V tolerant... - 3.3V) Traditional programming approach is the devices are normally "asleep" and wake in response to either timer events or external inputs. You'll find many, many code examples where main() code appears to stop at a low power mode entry point with no further main->executable code, nor a return statement. Others will feature a while(true) "forever" loop, but which also halts at a low power mode statement, and only executes subsequent statement in response to an interrupt event. FWIW, the LP line is inexpensive, very capable, and Energia allows an entry point for programming. As you progress you may find yourself moving to more traditional, programmer-oriented tools such as the IAR, CCS and GCC compilers, assemblers, and related linkers. This is a good forum is a good place to seek answers, as is https://e2e.ti.com/ Have fun! Bob
  8. Sigh... Rei: Thank you for the information.
  9. I've been developing a 'F5529 USB device and have a Java-based USB UI to control operating parameters. The intent with the java app is to allow "easy" access on both PCs and Macs (and of course, Linux too...). However, while I've got Windows and Linux machines here, I don't have any Mac devices. I'm seeing these older Mac notebooks for around $150.00, which doesn't break the bank. For those of you who are Mac literate, would one of these be a reasonable machine to test installation of both the HID aspects of the 'F5529 and functionality of the Java app? TIA! Bob
  10. @Biza It's not clear which devices you are actually using. Is it the '432 launchpad? And how are you connecting to the SD card? Is it a BoosterPack version? A simple schematic would allow a means to compare code with wiring...
  11. I'd like to know what comes of your testing when you get to it.
  12. Well, there's magical thinking... And then there's magic! While looking for a file I noticed my server had booted and was back online. Checked the logs and discovered the driver for my 8-drive 24TB JOBD external SATA enclosure had failed to load. This is a Highpoint Rocket Raid system. It's junk. Has been from the outset, but I purchased everything while relatively ignorant. And, as @yyrkoon has noted, enterprise hardware is mind-bendingly pricey. So, I use the system as not a backup, but as a secondary copy location for video, images and audio. Maybe after I win the lottery I can put a proper system in place.
  13. @yyrkoon I've thought about restoring my centos server - I took it out of service when I stopped writing my own websites; easier to use wordpress to manage blogs. Though, as you've noted, nothing is immune from some type of corruption, including my own thought processes...
  14. Interesting coincidence: My Windows R2 2008 server won't boot this morning - according to the diagnostics - bad driver due to recent update... This machine is set up with a failover shadow boot drive, and of course there are a month's worth (if I remember correctly) of system images. However, I'm REALLY BUSY right now. So, I'll limp along without fixing it today, maybe Sunday, or not... Who has time for this junk. Sigh Superstition ON Talking about backup strategies triggered this failure... Superstition OFF
