  1. I've been looking for a while and can't find a good example showing how I can play any sort of music or speech files (mp3, au, wav, etc.). I've got a configuration setup that allows me to read files for things like LCD screens, I'm looking to read a music or speech file and play it through an amplified speaker. I'm not looking to make just tones, rather to play full music or speech files. I've found projects for Arduino such as (http://hlt.media.mit.edu/?p=1963), but nothing that works with MSP430 and Energia. Has anyone done something similar to this with Energia?
  2. Hello, I am trying to measure voltage across a voltage diviter with a Tiva-C series boards, and I am consistently getting mis results. I get 0-4096 for 0 to 3.3V. I also have a seperate battery, that goes in to a 100K + 15K voltage divider network and PE_2 is connected to the middle of the voltage divider. It measures 1.1V approximately, when it should be measuring 0.77V. But here is the interesting part. When I use a multimeter to measure the same middle point in the voltage divider, it reads 0.77, and the value from the analog read also converges to 0.77 - then i disconnect the m
  3. 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
  4. 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 .
  5. I was wondering if the SensorTag (the current Bluetooth one) is going to have Energia support at any stage?
  6. Hello, I have been programming my Tiva boards with JTAG which works well for development but not for production. I did a bit of research to come up with a versatile system to load code into my Tiva boards. JTAG is very important for code debugging but a serial download or boot loader is also indispensable for production or in field firmware upgrades. Another indispensable tool is Energia. For fast and simple code generation, nothing works as well as Energia. I have come up with the following interface: a header on my boards with the JTAG pins, reset and TX0, RX0, and power. This header goes
  7. Uploading a very basic sketch 48488 bytes to the LaunchPad MSP432 requires up to 30 seconds. Is there a way to speed-up the process? Sketch size Upload log
  8. Hi, I wonder if it is possible to cause a interrupt when receiving serial data. This would have the big advantage to be able to wake up from sleep mode if new serial data is available. By now, serial data is written in the rx buffer even in sleep mode, but afaik it's not possible to notice that in Energia. I found lots of code for CCS for exactly this application, but i'm not able to port it for Energia. Does anybody already has some example code or may help me to make the CCS code working in Energia? Thanks!
  9. Hello, I want to design and make Cubesat OBC(On board computer) using MSP 432 & energia for eash coding and RTOS. But i am student and begginer. if i design like schematic for MSP432-Lunchpad, could i use energia without any other processes? if not, How can i use energia for my DIY board? and I want to connect SRAM to MSP432 using SPI communcation and control SPI using energia is it possible? Could i use fully functionality of RTOS using energia ? and if you any other advice, please let me know. I'd appreciated if you reply these questions. Thank you much.
  10. Hi guys, do you know if there is a way to set different priorities to different threads of a sketch? For example, if we had a slow thread which senses a thermomenter and another one which sends data serially bit-banging a pin, and another one which senses an emergency stop (whatever, just imagine they are all pretty fast processes) I would like to set a list of priorities for the underlying TI/RTOS to handle possible needs. Is there a way to implement this? Also... if we set interrupts to handle certain events... how does Energia signal the RTOS the priority for this (like in don't
  11. hello all! why are energia wire lib don't work? I have connected my launchpad 430g2553 to PCF8576 LCD 10. P1_6 to SDL and P1_7 to SDA . I try to write some code to use Software I2C Library but it did't work in energia . But EAR lib for software i2c work correct way. what i can to do to connect LCD with energia ? no software no hardware energia code don't work what 's the reason?
  12. I am trying to upload a sketch but am unable to, as there is no way to set the port, as the Serial Port option is greyed out in the Tools menu. I am running OSX 10.9.5, my device (CC3200 LaunchPad) is being recognised on the USB bus (see details below). USB <-> JTAG/SWD: Product ID: 0xc32a Vendor ID: 0x0451 (Texas Instruments) Version: 5.00 Serial Number: cc3200 Speed: Up to 12 Mb/sec Manufacturer: FTDI Location ID: 0xfa130000 / 6 Current Availab
  13. Hi, I am working with TEA5767 FM module to receive FM Audio. I have noticed a peculiar issue. When the launchpad is powered by my Laptop the communication works (only MSP430 <-> TEA5767 on I2C ) and I am not using the Serial which will anyway require my laptop. But when i power the Launchpad using a wall wart phone charger which is also @ 5V . It doesnt work at all. Since i am not using Serial. Laptop should not be required. The code is given below: #include <Wire.h> unsigned char frequencyH = 0; unsigned char frequencyL = 0; unsigned int frequencyB; double frequency
  14. Hello , I have used Energia for the Launchpad before with MSP430F5529. I am now designing my own board with MSP430F5528 . I was wondering if I can use Energia for it?When I try to program from Energia it has limited devices in its list. Is there any way?
  15. Hi, I am trying to get the ADC sample timestamp on Energia, but I can not figure it out how it works. From the TI API I know that the ADC data saved on the register is made by two parts. bits [13:0] : ADC sample bits [31:14]: time stamp per ADC sample So I took the Energia library. From <driverlib/adc.h> and I found a method that returns only the time stamp. //***************************************************************************** // //! Gets the current value of ADC internal timer //! //! \param ulBase is the base address of the ADC //! //! This function the c
  16. Hello i have seen article about reading the supply voltage from MSP430 http://www.elevendroids.com/2013/06/code-recipe-reading-msp430-power-supply-voltage-level/ It can be usefull when running on batteries however i am not able to find anything suitable to use for TM4C123. The system DEFINES carries another names and the code can not be used. I have only used Energia for programming my LM4F120. If anyone have some experience in reading the internall VCC a and Voltage Reference to compute supply voltage level on TM4C123 I would be thankfull.
  17. Hi Guys, My name is Nathan. I've lurked around here on 43oh a bit, but this is my first official post. I've been working with the MSP430FR5969 for several months now and I've quickly grown to really like it. It seems to me TI's FRAM processors should really be getting more exposure for battery powered development in both professional and maker communities. To that end - I was hoping to get some feedback on a product idea. We've packaged the FR5969 into a tiny coin-cell powered module. The module can operate as a stand-alone processor or it can plug into an UNO-form-factor breakout
  18. Greetings, I'm almost at the end of my project with my CC3200 sensor board, and I want to thank again people who helped me here, for the SFLS lib and my printf issues. From the begining with energia, I had (minor) issues of bricking my board with no real understanding of WHAT was causing it. I finally took (had) the time to narrow it down to a very specific scheme, so I'd like to pick your brains about it. background : - started with a launchpad (of the first revisions), tried different service pack, never got issues. That's only when I started with my own board and the CC3200 mod
  19. hello, i'm new here, and i want to know how to use PLL to change the tiva C systeme clock frequency? thanks
  20. I'm posting in the RedBearLab support as well - but I wanted to post the error I'm getting from Energia in the forums to see if anyone can help. I got the software from RedBearLab installed as well as the MBED serial driver. When I try to upload - I just get "upload failed" with no other detail. I tried Energia 0014 and 0015. OS is Windows 7 Professional, x64. This is the error I get when I try to send something via Serial Monitor. I'm hoping this might be helpful as to why my uploads fail. java.io.IOException: Bad file descriptor in nativeDrain at gnu.io.RXTXPort.nativeDrain(Nat
  21. Hello dear developers, I am currently working on an automated rover project working on multiple MSP430 the board in charge of the electrical power management embbeds a MSP430G2744 model. As I quite used to work with arduino IDE I tried to port it to Energia. Unfortunately I got stuck at some point editing my variant of pins_energia.h : The timers for the ported microcontrollers appears something like T0A0 T0A1 T1A0 ... etc On the MSP430G2744 however they only appear as TA0, TA1 etc. The Energia.h file in cores does not allow in its enumaration list for TA0, TB0 simple notations I
  22. Hi everybody, People might have read the hackaday post describing the ESP8266. The ESP8266 is a really low price Wifi chip, which uses serial communication (just like the Wifly etc.) to connect to wifi. Although the CC3100 and CC3200 are the better chips, the ESP8266 main differentiating point is its ridiculous low price. I've ordered 8 for $3.50 each (aliexpress). It doesn't seem to support IPv6 out of the box, but there is an SDK, which might open future possibilities. I was thinking to make a library for energia to support the ESP8266. Anyone interested? Are there specific starting
  23. Hi everyone, I wanted some strategic advice from the Forum on an MSP event I'm organizing in Rome next week (everyone is invited, the link is at the end of the post). I'm trying to introduce the MSP hardware/software platform to an arduinocentric audience who is unaware of other - better in my opinion - options such as ours. For the hands-on part, I'm basically going to open up a sketch in Energia - which they will recognize as an "Arduino in red" - and then I want to migrate it into Code Composer Studio, in order to show them what a professional IDE is all about and what it offers. My idea
  24. Hello, Today around 3~4 hours I have been trying to program my MSP-EXP430G2 launchpad using Energia. It looks like the FET in the board got bricked or something. When I connect the board to my Windows 8.1x64 machine it gets enumerated as the 'MSP430 Application UART (COM5)' which is good. But then when I use Energia to download a simple 'Blinky' example to the board it fails. It says, tilib: MSP430_Initialize: Could not find MSP-FET430UIF on specified COM port (error = 57) tilib: device initialization failed Also the device becomes 'Unknown USB Device (Device Descriptor Requ
