  1. Hello! I am using Energia to program TM4C123GXL board. The program performs a primitive data acquisition with low frequency and stores it (together with timestamps) as an array in RAM. I would like to store data in EEPROM or, preferebly in FLASH. Micro-controller has 256kB flash. How can I save data there? There is flash API (flash.h and flash.c) in lm4f/driverlib/ though I am not sure even at which address range I can write/erase data? Can anybody point out to a working example? thanks for help!
  2. Buy: The 43oh Store or Rob's Tindie Store. The newest version of the Ethernet BoosterPack is based on the newest chip from WIZnet, W5500. P1.5 - SCLK P1.6 - MISO P1.7 - MOSI P2.3 - /CS P2.4 - /INT P2.5 - /RST Configuration jumpers are on the bottom, PMODE1-PMODE3, LINK LED, and ACT LED. LED jumpers control which LEDs are used, on board or socket. Available on Tindie.
  3. Hi folks, sorry that I have so many questions in the moment, but I do not find to many other sources for help. I got a bunch of G2252IN20 for under 50cents a piece. Because of the pinout, that is quiet similar to the G2452 I thought I can program it with my launchpad. But when I put the chip into the launchpad, start mspdebug and try to download my code, I get the following error: Writing 818 bytes to 0xc000 fet: FET returned error code 7 (Could not write device memory) fet: failed to write to 0xc000 On an Energia site I found that this happens when you have choosen the wrong target, b
  4. I am uploading the fade example of energia to the tiva t4mc1294 connected launchpad but the LED is not fading. It is just blinking. I have also connected the pwm output to motor drivers but the speed of the motors are not changing. When I check the voltage of the pin with my multimeter, I get 0.66v. I have tried the fade example on different pins like PF2, PF3(pins marked for analogWrite in launchpad reference) but the results are same. Here is the code for the fade example, given as reference. int brightness = 0; // how bright the LED is int fadeAmount = 5; // how many points to f
  5. I want to implement wireless sensor network programmed with my own protocol suite. The memory size of Launchpad should be: RAM size 4 KB FLASH or FRAM 64 KB I plan to use MSP-EXP430FR5969 with CC1120. The resulted hardware is operated as standalone so it powered by energy harvesting circuit or battery. I'm not sure that I chose the right product for my project. Thanks in advance for any help or suggestion.
  6. Hi Guys; Recently time, I am using energia to programming microcontrollers. Especially, G2553 and TivaC. But I have some tackles when I change the launchpad which is C2000 F28027. I read all messages in this forum. I cannot manage with problem. First of all : I remove 0101E0016 version, because it has a cpp code problem for C2000. Secondly: I can compile with 0101E0014 version. But no Upload. Always same fault " JAVA Problem." All stiationm can be show the below images.

  8. Got an email today about a new LaunchPad supporting hardware cryptography - mainly aimed at supporting HTTPS for your IoT projects. Promo pricing $16.99, normally $24.99. http://www.ti.com/tool/ek-tm4c129exl
  9. I am using LauncPad MSP430G2 revision 1.5, MSP430G2553, Grove base boosterpack, Energia 0016, Windows 7 64-bit My project will need to start in the sleep mode. When I press the button P1.3, it will display on the LCD. And after 10sec, it will go back to sleep mode. Can somebody help me with the coding. PS : I am new to Energia and have never touched programming before. Sorry if i didnt make it clear enough.
  10. I have a CC3200 LAUNCHPAD and I'm using Code Composer Studio v6.1 with an Energia example. I try to build the WifiWebClient example and the lpcc3200_core library keeps giving me grief. It says that it can't find some header files but they're clearly in the project tree. Any thoughts on why this might be happening?
  11. Hello all! If anyone else is interested in devops tools like ansible/vagrant/docker or linux administration this project might interest you. I recently started learning about ansible a tool used to configure/orchestrate servers. So I thought I would try and use that to push firmware updates out to MSP430s. I came up with a solution that allows me to run a command on my machine which then copies the firmware to Rapsberry Pis and then flashes any MSP430 LaunchPads connected to them. I first had to compile the msp430 dll and the latest version of mspdebug for the ARM architecture (rat
  12. I have just published another blog post about the flight controller I have been working on recently and thought you guys might be interested: http://blog.tkjelectronics.dk/2015/08/bachelors-thesis-launchpad-flight-controller The source code is available on Github: https://github.com/Lauszus/LaunchPadFlightController. A PCB for a BoosterPack has been ordered and should arrive in a few weeks. In case anyone of you want to try it out yourself you can order the PCB yourself: https://www.oshpark.com/shared_projects/9DC5cp8eor simply wire it up on a prototyping board. The video below s
  13. Hi everyone, Just wanted to share my flight controller I wrote some time ago Here is a video of it: The code is available here: https://github.com/Lauszus/LaunchPadFlightController. You can read more about it at my blog: http://blog.tkjelectronics.dk/2015/01/launchpad-flight-controller/. Regards Kristian Sloth Lauszus
  14. Hi, Is it possible to add a custom board/ circuit to energia? If yes, please guide me with the procedure for the same. Thanks
  15. Hello! I recently bought a MetaWatch FRAME, with the intention of messing around with it as an inexpensive, portable MSP development platform. Meta open-sourced the watch's firmware and *used* to sell JTAG programming clips for the watch. Now, however, they've discontinued both my model of watch and its programming clips, and I'm out some cash on a less-than-fully-functional smartwatch. The watch uses an MSP430F5438A microcontroller and is programmable using the Spy-Bi-Wire protocol, according to this SparkFun teardown. I found the sticky post about programming MSPs with Launchpads, bu
  16. Hello all. I'm new to CC3200 and trying to develop an application for the launchpad using a Timer. Energia has the timer.h module, and I've found TI's documentation for the General Purpose Timer module, along with a few code snippets. My code dies when calling TimerConfigure(base, type). I think that this is because the timer peripherals need need to be enabled as a system peripheral before they can be manipulated. It looks like SysCtlPeripheralEnable(SYSCTL_PERIPH_TIMERx) is what you'd call before calling the TimerXxx functions. However, the cc3200 driverlib doesn't have a s
  17. Basic analogRead function doesn't seem working.. I am using Energia as a compiler. I am trying the minimum configuration. I am getting a value but this value doesn't change with potentiometer. I have even tried to ground the signal (to see if it is Zero) but nothing has changed.. What might be wrong? thanks .
  18. Hi all, Over at Temboo, we've just released a new feature called Streaming. It short, Streaming makes it simple to connect your MSP430 LaunchPad to cloud data storage and visualization services. You can learn all about it at the link below, and let me know if you have any questions! https://temboo.com/streaming
  19. I want to update the code for my MSP430F5529 but want an easy way to re-flash the old code if I mess something up. Does Energia (or some other utility) provide a way to download and save the ROM contents, and restore them from an image file?
  20. Hello All, I am a beginner to MSP430G2553, however all I am trying to do is get the MSP430 to execute the blink code while on 1.8V power supply. I have tried it on the launchpad board and it seems to stop working around 2.1V power supply. I then tried the barebones method by only using a bypass capacitor, pull up resistor for reset, and LED/current limiting resistor on a breadboard, but it seems that again the circuit only works down to around 2.0V. I measured the output pin while at 1.8V and it is in 10's of mV so it is not a problem of the LED getting degraded voltage levels but the
  21. Here I summarize the hardware connections (schematic given below) and source code (attached) to build a Distance meter using MSP430 Launchpad and Ultrasonic Sensor HC-SR04. Project: Ultrasonice based Distance Meter with LCD Display Microcontroller: MSP430G2231 on MSP-EXP430G2 Launchpad Ultrasonic Ranging Module: HC-SR04 16 msp_dist.c
  22. Hello, my plan is to use the built in serial flash memory of the CC3200 launchpad board (it holds 8 mbit, its a 25PE80VP from ST) for storing multiple GIF files. Can anyone give me a hint how to save/load from the serial flash and what is the type of file system? Sorry if its a nonsense question, i am quite new to CC3200... Cheers, Max
  23. I'm using CC110L Boosterpack with TIva C. I tried example codes provided in Energia. I want to use this boosterpack for my project. And I'm using Keil for programming. So any one can provide CC110L and SPI libraries for Keil???????
  24. Hi, I have a Mac desktop app that connects to a Connected Launchpad via USB serial. I decided to try to add ethernet port connection. I got tantalizing close but no cigar! I've been stuck on this for a week now so I need help. I had no problems adding the Ethernet.h library except for something very weird trying to do a conditional import. I have been using directives to compile for either the LaunchPad or the Connected LaunchPad: #ifdef PART_TM4C1294NCPDT // Connected LaunchPad #include "Ethernet.h" #elif defined( PART_LM4F120H5QR ) // LaunchPad #endif This seems to have bee
  25. Hello All! This is my first post on this forum. So kindly excuse me if i do any faux pas! I am planning to shift to MSP430 after using arduino for long time. I have written a small code to read ADC value and when i press a button adc value gets stored in a variable. Now want I want is to make available this value even after microcontroller restarts. Can anyone tell me how to store variable in Non volatile FRAM? I am using MSP430FR5969 launchpad. I have looked into following examples but they are of not helping me. I am using Energia to program my launchpad. http:
