  1. I plan on going ahead and fitting it all together - it is the quickest way for me to put something together that won't fall apart and demonstrate the concept.
  2. Receiver Prototype Working After some stop and start I am back on this project and making progress. Here is the latest iteration: The wearable IR receiver and WS2812 controller at bottom runs off of a single 2032 battery. With only one LED lit at a time it is capable of easily running for an hour since current is down in the 10-15 mA range. It also transmits and receives with high reliability at 10 meters with two IR LEDs as shown. The transmitter is battery driven at the moment. I have a large number of IR LEDs on order so as to build a transmitter with a larger array of L
  3. Mine is Rev 1.6 but I should point out that RX,TX only ceased working when I accidently applied 5 volts to a pin - it worked fine before that. I have several F5529 LaunchPads and all were working on receipt Why use a F5529? The LaunchPad itself Costs $3 more but it is faster, has more memory, more and better peripherals (eg faster UART and higher resolution ADC), has USB, etc. It is easy to use if you are familiar with the G2553 and need the features.
  4. A while back I damaged two pins on this board and dutifully marked it on the back. Unfortunately it was only visible from the back. Some time later I picked it up and was trying to use it unsuccessfully. After tearing my hair out for a while I eventually turned it over and noticed the markings. Now it is marked front and back.
  5. PUSH is not a variable in the example / library that I suggested above so you must not be following the suggestion. In your first post it is not defined. It needs something like #define PUSH xxx where xxx is a pin number / designation. Doing a search for "DHT does not name a type" on the internet will give multiple hits and solutions to the problem so you apparently did not do the search as suggested. The library is probably installed incorrectly.
  6. As stated above, I tried the library that I linked above with a TM4C123 / DHT22 the same day I made the post and it worked. Use the example code that comes with the library. I was probably using Energia V17. Do a search with google with the error message text if you want to understand what it means.
  7. @Rickta59 I would not have caught that It works for me in V17 but not in V18. When I move it in V18, it works. What is happening?
  8. @energia I just tried compiling the nRF24L01 library in V18 and got the following error: In file included from C:\Users\Frank\Documents\Energia\MSP-EXP430F5529\Enrf24_RXdemo\Enrf24_RXdemo.ino:16:0: C:\Users\Frank\Documents\Energia\libraries\Enrf24/Enrf24.h:32:17: fatal error: SPI.h: No such file or directory compilation terminated. exit status 1 Error compiling for board MSP-EXP430G2553LP. @ghjkl67 You should not have to add SPI. Try using Energia V17 as I suggested above. You will find it here under previous releases: http://energia.nu/download/ Energia V18 still seems
  9. How do you know it works as a receiver if you don't have anything working as a transmitter - what are you receiving without a transmission? Have you gone back and double checked that one of my suggestions isn't the cause? I can assure you that the library works when connected properly with the nRF24L01+ modules I have and a G2553 LaunchPad. The datasheet for the nRF24L01+ has all the details and can be found with a google search - it uses SPI. SPI keeps the chip select pin high until it is ready to transmit and then pulls it low. It then returns to high following transmission. The co
  10. I have used this library with both custom MSP430G2553 boards and the LaunchPad. Hardware setup is the same whether receiver or transmitter. Among the possible problems and solutions are the following: Bad nRF24 - the very first one I bought was bad damaged pin on MSP430 - don't apply 5V to a pin - this is a 3V3 device nRF24 wired wrong or wrong pin in software - easy to do poor transmission between modules - too far apart, object in between, or even too close together. modules set on different channel or other incompatibility in way software is set up In gen
  11. You haven't provided enough information to get help.... Most importantly you have not stated what about the code is not working. Is it failing to compile? Is it giving bad results? Is it failing to print? You haven't stated which library you are using, etc... So, anyone attempting to answer your problem would just be guessing. Try using the Adafruit library without changing anything and have it print directly to the serial monitor: https://github.com/adafruit/DHT-sensor-library Use pin 2 (PB5) on the LaunchPad. I just tried it on my TM4C123 and it worked. Once that is working, tr

  13. Hi iKlepto and welcome to 43oh... You can get jumpers M-M, M-F, F-F. For example.... https://www.addicore.com/Jumpers-and-Cables-s/1837.htm and many other places
  14. Hi @jBrizzle and welcome to 43oh... Maybe use a little module? Depending on your needs in terms of recording length and number of recordings that might work. I have used these although not from this vendor: https://www.amazon.com/Sound-Voice-Recording-Playback-module/dp/B018Q6TAEQ/ref=sr_1_2?ie=UTF8&qid=1489447073&sr=8-2&keywords=isd1820 They are cheap and work for a single recording but the amplification and quality isn't great. They can be controlled with a microcontroller. Maybe this: http://processors.wiki.ti.com/index.php/Audio_Capacitive_Touch_BoosterP
  15. You appear to have taken on a project which is beyond your current capabilities. If you are a student, consider going to your professor/instructor for help or getting a simpler project. There are too many problems with your code as it stands to offer help in this forum - at least for me to offer help.
  16. Hi @@devdibyo and welcome to 43oh Try using the hardware, i.e. Serial1 as described here: http://energia.nu/reference/serial/ Take out the following: #include <SoftwareSerial.h> SoftwareSerial mySerial(P3_4, P3_3); Replace all instances of mySerial with Serial1.
  17. Hi @@osmanfish and welcome to 43oh, Irritating isn't it? It can be caused by several things. It can happen with the MSP430G2 and Energia if you are using serial print and close the serial monitor down while the sketch is printing. This does not seem to happen with other LaunchPads. Try unplugging the LaunchPad at the computer and then plug it back in. You may have to try uploading one or more times to get it working again. Also, avoid shutting down the serial window. Flash (upload) the target chip without shutting the serial monitor. If this does not seem to be your problem then
  18. Hi @@SheldonMaciel, I don't have a working CC3200, but I do have a CC3100. I tried it just now with a F5529 using Energia V18 and the SimpleWebServerWifi example - it worked fine. You can try the following: make sure the jumper is in place as shown on the pin map for Energia revert back to the former version of Energia and/or CCS and try what worked before
  19. I suppose this is asking for quite a bit . But for those who really are interested in learning and getting a response to questions the following is a good link that also applies here: https://e2e.ti.com/group/helpcentral/b/weblog/archive/2015/07/17/5-tips-for-getting-quick-help-on-e2e It might be this can only be accessed if you are a member of e2e - not sure.
  20. I modified the TI DriverLib example for the RTC_A on the F5529 to demonstrate the same thing as the Energia library for my own educational purposes and placed it here: https://github.com/fmilburn3/MSP430F5529_driverlib_examples/blob/master/11A_RTC_A_calendar_mode
  21. I modified the code in the link above a bit and wrote a new example to demonstrate retrieval of the date and time as well as a few other features. It was not extensively tested. To use, post all of the files into a folder called RTC_F5529 where Energia can reach it. It is posted here: https://github.com/fmilburn3/RTC_F5529 Real credit for the work belongs to the original author.
  22. Have a look at this post: http://forum.43oh.com/topic/5421-energia-library-rtc-a/ I haven't used it in a project, but the post states that it runs with the F5529. It is not clear what your final objective is and whether you are trying any of this code yourself - try to get it working yourself first. If you have specific problems then post your objective, the code and the issue / error message you are getting. The original author may be willing to help and I will help as time permits. I may try running it myself this evening.
  23. Hi @@Neetee, Don't double post - it is bad etiquette. Your original post was not ignored.
  24. I seem to remember someone posting a RTC example for the F5529 in Energia on 43oh a while back. In any event, as Terje says, the F5529 has a RTC module and there is driverlib support which can also be included in Energia. See these examples, one of which has the RTC module: https://github.com/fmilburn3/MSP430F5529_driverlib_examples The advantage of an external clock like the one Terje linked to is that they have a coin cell. Arduino code is usually easily ported. For that matter, MSP430 code like that linked by chicken is pretty easy to port between variants.
  25. Yes, of course. When you ask for advice, always specify the compiler/version you are using as well as the LaunchPad. Also, describe or post a photo of the circuit where it makes sense. Fully describe the problem and where possible give sufficient information for others to duplicate the problem. There is a button below posts in 43oh where you can thank others when you get help. The following was done in Energia V17. First, set up a source for Serial1. I used a F5529. TX for Serial1 is on pin 4. Here is the code, it outputs the 255 characters on one line and then starts over: void
