  1. 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:
  2. Hey, when I try to upload the program through Energia, it shows "no unused fet found" what should i do.?
  3. Hi, I've made a very simple RTC library using the RTC method in the PRCM library. It is intended for the CC3200 Launchpad and has only been tested on the CC3200 Launchpad so far. Overview: Uses the PRCM library It follows UNIX Time It was made with the "Time" library of the Sparkcore in mind. It has the following methods:ccRTC.zone() ccRTC.now() ccRTC.year() ccRTC.month() ccRTC.day() ccRTC.weekday() ccRTC.hour() ccRTC.minute() ** ccRTC.begin() Limitations: (Unfortunately there are a few actual limitations) It is accurate to only about 4 seconds an hour. (That is pretty bad, but
  4. In the Energia port for the CC3200, will there be an avr/pgmspace.h replacement to help manage access to the program memory? If it is not already in the works, would such a thing be workable? As I understand it, the CC3200 stores program in an external memory, and loads it into RAM for execution. The AVR has two memory spaces (program and data), and on Arduino, avr/pgmspace.h defines various macros, etc. for using data in program space. Seems like it might be possible to create a pgmspace.h (and accompanying library) which would allow use of data stored in the CC3200 external memory
  5. I have been attempting to work with serial communication between the board and other devices, but cannot get them to communicate while on connected to the booster pack rails. The only time I have ever gotten any Serial communication to work is by connecting a UART device to J6 & J7 in the middle. Is there a different Pin configuration I need to get those to work? I switched the jumpers on J6 & J7 down after downloading my code to the CC3200.
  6. I am trying to run an Arduino program on MSP-430G2452 using Energia. My code is sending data to PROCESSING(I.D.E.) on my computer via usb, to change the colour of a box(made using processing) when a switch is pressed. But it seems that the processing is not receiving anything from the board. Can anybody please tell me what wrong I am doing ? The same code is running properly with the Arduino! CODE FOR ENERGIA:- int switchPin = 7; int LEDPin = 13; void setup() { pinMode (switchPin, INPUT); pinMode (LEDPin, OUTPUT); Serial.begin(9600); } void loop() { if (digitalRead(swi
  7. Tutorial maybe should mention the term Larson Scanner, which seems to be a general term for the bouncing back and forth light effect, used in Cylons in Battlestar Galactica, and then re-used in Knight Rider (as mentioned in the item). http://energia.nu/Tutorial_ForLoop.html Are there earlier uses of/terms for this effect?
  8. Hi, I know Energia today and tried the example code "Blink" of Energia, but it shows "Upload failed.". More output is like below.

  9. Hi! I tried to connect GPRS Shield from Arduino to msp430g2553 with SoftwareSerial library. But I faced with the problem. When the size of sketch exceeds 5590 bytes, global variables do not work. I just add one variable (global string) and the program stops executed correctly. Here is the code: /* When new serial data arrives, this sketch adds it to a String. When a '!' character is received, the loop prints the string "Hello world!" */ #include <SoftwareSerial.h> SoftwareSerial mySerial(P2_0, P1_5); String inputString = ""; // a string to hold incoming data boolean st
  10. TI has launched a PRU cape for the BeagleBone dedicated to the PRUs. Has someone tried to adapt Energia to program those PRUs on the BeagleBone?
  11. Hello , I have been trying to play with the recently bartered CC3000 BP with my TIVA C 123 LP using Energia. I noticed the following things: Has the support for CC3000 been depreciated in x13 Update as the information mentions : " Circuit: * CC3200 WiFi LaunchPad or CC3100 WiFi BoosterPack with TM4C or MSP430 LaunchPad" ? When flashing the code to the LP(TIVA C123) with CC3000 BP for "ScanNetworks". The serial data hangs after showing:SimpleLink SDK 0.52 I then tried with the older version (x12) I updated the firmware and it kind of started to talk. Until it stuck at the IP. After r
  12. I posted four New LaunchPads and BoosterPacks Pins Maps at the 43oh forum.
  13. Two problems with delayMicroseconds on Tiva (and I believe on CC3200) 1) The delay interval is erratic, appearently because delayMicroseconds does not handle rollovers of the systick counter correctly. 2) delayMicroseconds can not work for dealys longer that 10,000 microseconds. (Even though the documentation says that it works up to 16383, and even includes an example.) Details: Issue 1) Code to demonstrate problem: #define DELAY_FOR 5000 void setup() { Serial.begin(9600); Serial.print("Delay"); Serial.println(DELAY_FOR); Serial.print("elapsed tics should be: "); Se
  14. Hello world, If your project has outgrown the capabilities of the Energia IDE, why not try Gnu Make? I've put together a set of Makefile fragments which support Energia (msp430 and lm4f) and Arduino 1.0, here: https://github.com/jscrane/uC-Makefile. For most projects, a Makefile as simple as this suffices: Followed by: Cheers, Steve
  15. What is the preferred way to stop doing analogWrite (PWM) on a pin in Energia? For instance how should I change a pin to digitalWrite, or change it to input, or to just prepare to stop using the pin? In particular, how do you stop the timer (which is used to generate the PWM)? Studying the code for analogWrite, digitalWrite and pinMode I do not see where PWM timers are ever stopped once they are started. (I looked at the code on MSP430, Stellaris, and CC3200). To confirm my impression, I ran a little test on an MSP430. While I can change mode to output and/or do a digitalWrite
  16. I am happy to announce that release 0101E0012 just went up on energia.nu. I want to thank everybody for their support and contributions. Energia would not have been possible without such an awesome community! Details of the release can be found on http://energia.nu
  17. Tiva/Stellaris programs were compiled with optimization -Os in Energia E0012. (Optimize for size). In Energia E0013 optimization is turned off for Tiva/Stellaris and CC3200. (-O0) How do I turn optimization back on in Energia E0013? I have been working on a Arduino/Energia library which has a timing critical interrupt handler. Of course there is the #pragma route to controlling optimization. But is there a way in the IDE, or in preferences.txt, is #pragma the preferred method. On a somewhat related note, are there any release notes for the new version (which might cove
  18. @@energia @@bluehash As far as the maintainers of Energia are concerned, what is the relation between the Energia forums on Stellarisiti and those here on 43oh? As far as I can see, the energia website and documentation only point people to the 43oh forums for posting questions (regardless of which launchpad they are using Energia with). "The Energia discussion forum is hosted on 43oh.com courtesy of bluehash." http://energia.nu/help.html https://github.com/energia/Energia/blob/master/www/help.html and in the page footers for documentation corrections suggestions, e.g. http://energia
  19. Hi all, I have downloaded the energia sdk(version 13) for CC3200 launch pad, I have configured the jumper wire for J8 and SOP2 also the rest jumpers. Apart from that , I updates the firmware , so I have tries all possible ways, but still my serial monitor is not working. The platform is windows.

  21. I received my MSP-FET yesterday-- thank you TI! I was so excited to try out everything. I was deflated to find out that my package only contained the programmer-- hopefully the target board and MSP430FR6989s will arrive soon. It almost felt like Christmas morning-- only to find out the batteries were not included! I wanted to test out my new toy so I hooked up the MSP-FET to some MSP430 chips I hand nearby. I hooked up the MSP-FET to a MSP430G2231 and started Energia on Mac OS X 10.9.4. Although the MSP-FET is seen by the OS, I can't seem to connect to it. On System Info, the vendor/produc
  22. Hi, I used the search box but I didn't find what I need. I have a Macbook Pro retina display, bought on february.It has MacOS X 10.9.4 and I downloaded Energia to make a work for the university. I tried to upload the Basic example of Blinking the leds BUT I get the following error messages: rf2500: can't claim interface: permission denied rf2500 : failed to open RF2500 device. Just to let you know, I followed all the instructions from Energia website to install the SW but I get this error. Can someone help me to find out what's wrong? Thank you
  23. How can I add a switch to the g++/gcc command line (or do something equivalent) in Energia? I am importing a library (FastLED) which generates a bunch of warnings about needing -std=c++11 Example warning message: FeatureDemo.ino:655:98: warning: extended initializer lists only available with -std=c++11 or -std=gnu++11 [enabled by default] I would like to make those warnings go away (both for me, and be able to tell anyone else using the library how to make them go away). I have hunted through the menus, through the customization file and looked at the gcc documentation (for
  24. Hello to everyone, I am new to this forum after playing around happily with TI MSP 430 and also a bit with Stellaris Board. Mostly with Getting Started with the MSP430 Launchpad from Fernandez/Dang as my reference. So far so good anything did work well but I am just wondering if someone thought about porting Energia in a way that it would run on a Raspberry Pi Bramble( clust er of RPi) And by doing that also being able to run DEV on RPi only connected to USB hubs for power. The HDMI monitor excluded. Thanks in advance for any feedback Regards Gottfried
  25. In at least two places the Energia documentation claims that LaunchPad pins can source or sink up to 40 mA. Is that true of all (or any) of the launchpads supported by Energia? (i.e., Stellaris/Tiva, Tiva Connected, MSP430, Fraunchpad, C2000, CC3200) For the Stellaris launchpad, the documentation for the LM4F120 gives drive strength options of 2, 4, or 8 mA, and says up to 4 pins can sink 18 mA. So where does the 40mA come from (or go to)? Yet energia.nu says: "LaunchPad pins can source (provide positive current) or sink (provide negative current) up to 40 mA (milliamps) of current to
