  1. I still don't have a new F5529 Launchpad but wanted to tinker a bit more with Energia. Added another variant to use the MSP-EXP430F5529 http://www.ti.com/tool/msp-exp430f5529 It is not complete but the leds, buttons, i2c, and debug uart are all working. Next is wrapping up the timers then adding drivers for the on-board LCD, SD and Accelerometer. Add this to /energia/hardware/msp430/boards.txt lpmsp430f5529_25.name=exp-msp430f5529 (25MHz) lpmsp430f5529_25.upload.protocol=tilib lpmsp430f5529_25.upload.maximum_size=131072 lpmsp430f5529_25.build.mcu=msp430f5529 lpmsp430f5529_25.build.f_cp
  2. As an electrical engineering student at John Brown University, we were tasked with creating a useful product or service using the combined skills gained through our embedded systems class. As someone who likes interior decorating and hates mismatched paint, I came up with the idea to make an RGB color sensor attachment for a camera. Of course converting RGB data to paint colors is not conventional, it is something that could potentially be viable. To make things interesting and for the experience of working with a Raspberry Pi, I used a raspberry Pi camera to act as the base for the project. A
  3. Hello guys i have a project at my school were i need to make an energy metter with a msp430f5529 and a hardware part i did all the code myself and the hardware part (current metters,voltage divider etc), (i know is rudimental and ineffective) , the code and the montage works well and does everything i need it to do.Now my professor asked me to save "energie1" and "energie2" so when my microcontroler runs out of battery this 2 variables are saved , i read a lot of threds but i can't figure it out.Here is the code if it helps ( i can provide you with hardware montage if needed). #include
  4. I've been playing with Adafruit's ADXL345 accelerometer BOB and was able to import and run the Adafruit library code without any edits. Sweet...
  5. 2 years ago I had a small project using a F5529 LP with TMP006 sensor booster pack, connecting to an OpenWRT router using serial to send data to ti.exosite.com, and also a 16x2 LCD readout. Last month it suddenly stopped sending data. Trouble shooting confirmed the problem is at the serial part on the LP. The LP also refused being re-programmed during the trouble shooting tests. The F5529, TMP006, and OpenWRT are all confirmed working flawlessly. Another lost feature is the ability to show time on the LCD which it retrieves from exosite everytime data is sent successfully. A nice clock als
  6. Hi, I have an MSP430 F5529 LaunchPad, R1.6. I am trying to use the Wire library to access I2C BoosterPacks. The problem is that the Wire library is accessing the I2C0 interface on pins 14 and 15, while the BoosterPack is connected to I2C1, on pins 9 and 10. How do I select which I2C interface the Wire library uses? I tried using Wire0 and Wire1, but these result in a compiler error -- Wire is the only object defined. Aren't pins 9 and 10 preferred for the I2C interface according to the suggested pinout? If so, then shouldn't the Wire library default to using this interface?
  7. Hello everyone! Just wanted to say thank you for all the support and guidance everyone in this forum has towards beginners, you guys have been of so much help!! Now, here is a question: I am trying to interface 2 microcontrollers, a MSP430F5529 with a C2000 F28335 I was told the MSP doesnt support CAN, I would have to convert SPI to CAN and go from there. What do you guys suggest? I have never successfully used communication protocols. Any good examples of send and receive out there? Thanks in advance!
  8. I've got an F5229LP app that sets SMCLK to XT2 with a divider of 4. (XT2 = 25Mhz crystal, which is also the source for MCLK) When I initialize the clocks, HardwareSerial no longer produces an accurate Baud Rate, and it breaks terminal communication. I see that HardwareSerial.cpp contains: #define SMCLK F_CPU //SMCLK = F_CPU for now I've tried changing it to F_CPU / 4 but the situation did not improve. Here is my recreation code: (Uncomment initClocks(25000000l); and change HardwareSerial.cpp to see it fail) #include <WString.h> void initClocks(uint32_t mclkFreq); void SerialT
  9. This piece of code was made possible by Trey German, Robert Wessels, and Cathy Wicks of Texas Instruments. Without Trey's knowledge and Cathy's encouragement, I wouldn't have been able to make this program. Robert is the one who told me about this project. When creating 430AlarmClock, I adhered to my usual procedure for designing programs: 0. Make a general outline 1. Get the hardware 2. Write the basic stuff 3. Tweak, test, repeat until it works 4. Add/remove/tweak more advanced features until you are satisfied 5. Publish, add license, do whatever else you need to do I made the outli
  10. Hello, I want to connect my MSP-EXP430F5529LP ("MSP430") LaunchPad to an external device via I2C. Which I2C port should I use? (1) The MSP430 Quick Start Guide (slau536.pdf) includes a diagram of the BoosterPack connector showing two sets of I2C ports: -set#1- I2C - SCL - PM_UCB1SOMI - PM_UCB1SCL - P4.2 I2C - SDA - PM_UCB1SIMO - PM_UCB1SDA - P4.1 -set#2- UCB0SDA - UCB0SIMO - P3.0 UCB0SCL - UCB0SOMI - P3.1 (2) I am using the sample project, usci_b_i2c_ex3_masterTxSingle.c.

  11. According to the docs, it takes ~100 microseconds: http://energia.nu/AnalogRead.html. I measured this and it seems to be almost exactly 100 microseconds. Why does it take so long? This limits me to 10kHz sample speed. By the way, how fast have any of you guys sampled on the ADC12 of F5529?
  12. I'm trying to create an interface to collect data from some sensors using MSP-EXP430F5529LP. The sensor setup is powered with 3.3V and draws about 10mA. I noticed J10 on the LP has 3.3V and GND. When powered with USB, can this provide enough power? If not, I'll need to hook up VREF+ and VREF-. According to the data sheets these are pins P5.0 and P5.1. How can I hook up to these, as they don't seem to have a place on the 40-pin headers?
  13. Everyone knows my obsession with building an ECU for my motorcycle. I think I'm far enough along with it, so here's where I'm at. It's based on the 40 pin BP headers and I believe should be compatible with the F5529 and TM4C123 LP's and maybe more. I still have to code for it but that will come when I'm satisfied with the hardware. The BP will sit on top of this board with its USB plug facing away from the 25 pin plug, and has the I2C and SPI ports left unused which would provide for a display, data logging or other devices to interface with it. Eagle files attached as well. 4 low-i
  14. From the recent email received from TI announcing their new Connected LaunchPad line, I noticed the free partner service offered to Exosite. It is really cool to have the services of this kind, easy to configure for such a sophisticated communication platform. My only problem is I don't have one of those new shinny Connected LP.. actually TI won't sell those to where I live. But that doesn't stop my drive to test out this new exciting cloud! Firstly, an F5529LP with TI TMP006 temperature booster pack was selected as the test rig. This was a small project from last month that also w
  15. Anyone experimenting with this or have any thoughts on how this could be done in Energia? I'd like to do something like this with my MAP pressure sensor thing, where the user could drag and drop (or software on the computer could save) 'tuning' files to the device and that the unit would use for mapping its pressure sensor to the DAC. If possible, I'd also like to extend this to applying firmware updates in a similar fashion.
