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

I'm exploring TI-RTOS and developing easy-to-use libraries for Energia MT. The idea is to encapsulate each RTOS element into a class. Up to now, I've implemented the following libraries: Event library with choice of event number Event_Id_00 ... Event_Id_31 Semaphore library Mailbox library Timer library- 29 replies

Hello everyone, I have trouble with i2c on FR5969 launchpad. I wanted to interface a BMP180. As it didn't work, I tested my module on my TivaC launchpad and Arduino and it was OK. So I connected my oscilloscope and my logic analyzer on pin P1.6 and P1.7 and there was strictly no activity ... Searching on the internet I couldn't find any person using i2c on this launchpad, so has anyone tried to play with i2c on it ? Problem detected on Energia v15, v14 doesn't work too. I looked at pins_energia.h, it seems ok ...

Hi, I am using Energia ethernet library for Ti Tiva c 129 Launchpad. I wrote a simple program in Energia that gets a byte from stream and sends back two bytes. It seems there is lag when I send bytes back from Ti board. Here is my code. byte mac[] = {0x00, 0x0A, 0xB7, 0x52, 0xBA, 0x16 }; IPAddress ip(192,168,1,192); IPAddress gateway(192,168,1,1); IPAddress subnet(255,255,255,0); EthernetServer server(80); EthernetClient client; void setup() { Ethernet.begin(mac, ip, gateway, subnet); server.begin(); Serial.begin(9600); } void loop() { byte buf[2]

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.

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

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!

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 -
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

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.

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?

Hello everybody, 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 under

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

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

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

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 -
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?

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? -
It appears that tone() and noTone() were left out in the port of Energia to MSP432.

greetings, my wireless sensor project using the CC3200(mod) is coming up great and progressing fast. As I'm porting some code from my previous platform (pic + CC3000), I'm having trouble with the usual suspect printf. on the one hand, I've used simplified variants of printf in some arduino programs but I would definitely have the use of the full versatility of the stock printf as I'm far from the code size limit. In my previous platform / compiler, I just needed to provide the low level function that maps the output of printf to the UART, like putc or putchar. I've also read a
