  1. Hello, I'm currently working on a project temperature data logger. Now I'm using mc: MSP430f5529 I integrated with sd card using the petit fatfs library. Due to some limitation, i cant use full functionality. so I'm planning to make it work on fatfs. but there is no footprint for that. can you help me to come out of this issue? Thank you, sir Limitations: 1. Cant create a file 2. while saving the data in the same file previous entries are all given garbage value at sometimes. because it is not an empty file filled with null.

  3. Hi , I am using MSP430FR4133LP , in energia the GPIO pins are predefined in the pins_energia.h for MSP430FR4133 LP based on the silkscreen on the board. I using this MSP430FR4133 chip for another project and in that i am not using a LCD so i thought that i can also use LCD pins as GPIO. For this purpose i need to add the pins in the pins_energia.h but i am not able to crack it. Can anyone help me with this ....? if i try to use any other pins other than the defined ones (say P2_2) ... it throws an error as " P2_2 not defined in the scope" // Pin names based on the silkscreen
  4. I am currently testing the MSP430FR5994 launchpad. The available sram memory is 8Kbytes, but it is declared at 2 Kbytes in the boards.txt file. It is a mistake?
  5. The iMeter BoosterPack features the INA226, an iteration of the INA219 I've been using in various projects like the I²C Voltage-Current-Power INA219 Sensor and the Volt-Amp-Watt-Meter for Grove.Compared to the INA219, the INA226 operates on the same I²C bus but can now perform the measures on the high- or low-side, when the INA219 could only measure on the high-side. The library for Energia was then easy to develop thanks to the prior experience with the INA219. I tested the iMeter BoosterPack on a MSP430FR4133 LaunchPad and a MSP430FR6989 LaunchPad with the built-in segmented LC
  6. Hi, I am trying to implement Modbus RTU slave over TCP/IP using TIVA Tm4c1294 connected launchpad. The code has been successfully tested using Arduino. However, when I use the same code in energia, the launchpad gets pinged, but Modbus RTU does not work . Is there any library, hardware configuration which I need to change while migrating fro Arduino to TIVA? MgsModbus_test_Slave.rar

  8. MSP-EXP432P401R Energia 1.6.10E18 Windows Education 10 x64 v1511 I am wondering if anyone has had experience or knows how I could make it so a board [RED LaunchPad /w msp432 EMT (48MHz)] will be available to all users in a domain environment. I originally tried using the CCS Cloud TI Agent but encountered some very odd registry issues with non admin users/domain users (Reference: https://e2e.ti.com/support/development_tools/code_composer_studio/f/81/t/650118#pi316318=2). We are able to install it fine for everyone with the local admin or administrative domain account, however wh
  9. Hi, I am trying to connect my MSP430FR2433 Launchpad to Energia. I do not see how to select this board in the "Tools -> Board" setting, and I do not see how to download the drivers for it in the board manager. Yet on the homepage of energia.nu, it states that support for this board is available. Does anyone have any suggestions on how to get this board to work in Energia? Thank you. -Grant
  10. Part Number: TM4C123GH6PM Tool/software: Energia 1.6.10E18 LaunchPad board name and version: TIVA TM4C123GH6PM IDE version: Energia 1.6.10E18 or CCS7.0 OS name and version: Windows7 While uploading a simple LED Blink code on Tiva TM4C123GH6PMevaluation board, I get an error "Failed: Unable to find an entry in the TPI ini file for "TMS470REX"", failing to upload to the device. Please help!
  11. while integrating GPS with my msp430. I'm getting these errors from the library. so please someone help me out. C:\Users\softdesigners\Desktop\energia-1.6.10E18\libraries\SoftwareSerial\SoftwareSerial.cpp:81:2: error: #error This version of SoftwareSerial supports only 16MHz processors C:\Users\softdesigners\Desktop\energia-1.6.10E18\libraries\SoftwareSerial\SoftwareSerial.cpp: In member function 'void SoftwareSerial::begin(long int)': C:\Users\softdesigners\Desktop\energia-1.6.10E18\libraries\SoftwareSerial\SoftwareSerial.cpp:251:31: error: 'table' was not declared in th
  12. I am trying to read a .wav file from sd card and play it using I2S on CC3200 audio booster in Energia. I have modified the Wifi audio example of CC3200 sdk for this. The dma is setup in ping pong mode and sd card loads data into the buffer but the tx dma interrupt fires only once in primary mode and once in alternate mode. I could not understand why its firing only once. I have configured I2S in stereo mode with 16KHz sampling frequency and 16 bit size. This is my tx dma handler .
  13. Hi all, I started writing a few "hybrid" code examples based on Energia projects. They're called hybrid because they're based on Energia examples but are written more of a compact form, using few header files. For example, they do not try to hide the main() routine like Arduino/Energia (this is great for beginners/prototypers, but not for understanding the microprocessor). Energia and CCS examples are somewhat complementary: Energia is easy to use/hard to follow, TI code is hard to use/easy to follow. Hi-level vs. low-level. So I wanted something in between. Hence, hybrid. They a
  14. Back in June, I wrote a very basic sketch that sent an email via my hosted SMTP server. Unfortunately, the USB drive I stored the sketch on is toast. I don't recall the source and after digging through the examples, libraries and the forum, I'm unable to find an example I might have drawn from. Does anyone have an idea of what code example I might have used? I know I didn't write anything from scratch. I also know I didn't use Temboo or SMTP2Go, as I still have the email in my gmail mailbox (and it came from my hosted domain).
  15. Hi, I am looking to interface CC3200 Launchpad with Kentec K350QVG 3.5" LCD Booster pack using Energia. I can't find any library suits for CC3200. Does anyone interfaced this display with CC3200? If so, can any one guide me? Thanks
  16. hi, I am using a MSP430FR4133 launchpad, i am trying to get a float value and send it via sim800. for that i hve to convert the float value to char* or char array. I have tried many conversions but i am not able to get the conversion properly. Even if i get it properly while printing it on the serial. The data is not transmitted in the right format through sim800. for example if i use dtostrf( buff , "%f" , flaotVal); function in serial monitor only "%f" is getting printed. and if i try other type of convertions , while transmitting through sim800 the right side part of the floa
  17. Is it possible to use asm in energia? I would like to see some short and simple example of how to use it and compile it. I found THIS very nice and useful guide to make it work in code composer studio, but unfortunalley I could not put this code it to work in Energia, and I dont have CCS.. (I downloaded the version 7, but for some reason it did not install, just give errors, tried in 2 pcs) In the other hand, I found something about asm in Energia here in the forum, but is was intended for a more complex stuff, and I could not put it to work, too.. Could someone give me a light?
  18. Hello, I want to design a datalogger and to create USB Mass Storage when I connect board. I did not find Examples related to MSP430F5529 for Energia. So, please suggest me Energia example/SDK related to "MSP430F5529". Thank you. Regards, Pratik Panchal
  19. Hello, Just getting back into the microcontroller development aren. In the nineties I got very familiar with the Intel 8751 all programming in assembly. Times have changed! A lot is easier now, but learning the new IDE and knocking the rust off my C programming. We picked the MSP430 for the low power consumption. Like others I had a little trouble getting Energia running but now no problems. First project completed was a remote oxygen pressure monitor for the airplane. We have also connected the LIS3DH accelerometer and have it working well. I haven't figured out exactly how to im
  20. Check the usual suspects: Is the I²C bus initialised? Wire.begin(); Does the I²C device run at 3.3V? Otherwise, use a logic-level converter. Are pull-ups installed? Try 10, 4.7 or 2.2 kΩ for the SDA and SCL lines. In case the LaunchPad provides multiple I²C ports, is the correct port selected? Try Wire.setModule(0); // or other port number Wire.begin(); Still nothing? Use a logic analyser to trace the signals on the I²C port. (To be continued...)
  21. Model of LaunchPad: MSP430G2553/G2403 and revision number: 1.5 Model of the MCU used: I am not sure, but the box is MSP-EXP430G2 Name and version of the IDE used : Energia version 0101E0017 (I tried the newer one, but it threw a bunch of errors which resolved when downgrading) OS the IDE is running on Ubuntu 16.04 LTS I am completely new to this type of programming, so I apologize if I need extra clarification or am missing something. Issues faced: The blinking code I have used all work just fine, but no print statements work. My cur
  22. Is there a full energia porting for msp430fr5969, i.e. all the ports and full mcu functionality (timer, spi, i2c etc) rather than limited as per the launchpad? I have msp430fr5969, custom board connected to bunch of sensors and radio and would like to use energia for this. Any directions or suggestions will be most welcome. Thanks
  23. Hi everyone, I am using a Black Launchpad and this does not work in the latest version of Energia which is 1.6.10E18. So I switched back to the version 0101E0017 to make use of the Black Launchpad. My code is below and tried in Arduino IDE and working fine: float a = 3.5; float b = 2.0; float result = 0.00; void setup() { // put your setup code here, to run once: Serial.begin(9600); } void loop() { // put your main code here, to run repeatedly: result = max(a,b); Serial.println(result); delay(1000); } Using the same code
  24. I'm using the latest version of Energia and I'm facing some problems with it. I'm a beginner and I tried running an example program on the MSP430G2553. I get this error which says: Energia: 1.6.10E18 (Windows 8.1), Board: "MSP_EXP430G2553LP" In file included from C:\energia-1.6.10E18\hardware\energia\msp430\cores\msp430/Arduino.h:3:0, from sketch\Blink.ino.cpp:1: C:\energia-1.6.10E18\hardware\energia\msp430\cores\msp430/Energia.h:339:26: fatal error: pins_energia.h: No such file or directory compilation terminated. exit status 1 Error com
