Hi, I am not familiar with CCS and a novice in TI Launchpads. I have written an Energia code and would like to burn it into CC3220SF launchpad Flash memory so I could execute the code while disconnected from PC USB. I looked at e2e.ti.com/.../2495478, but did not work for me. Could you please guide me achieve this? Thanks, Sam

Hi all, I need to import/upload data to my MSP432P401R to call upon in future programs. Since I want this data to exist and be saved when my MSP432 is offline/powered-off, I decided that saving it to flash is the way to go. However, I don't know how to do this. Can anyone offer guidance or suggestions? Or does anyone have a better way of doing this? I'm using Energia v18.

Good morning (or good evening)! First of all, if these questions are stupid, don't spare my feelings. I know better than anyone that I'm still new at this and I have thick skin. I've had a great deal of success writing my own sketches with Energia. It's fun, simple-to-use, and easy to explain to others, but I have a few questions: 1) is Energia suitable for firmware in a small commercial product or is it intended more as a rapid prototyping framework, with "permanent" firmware written in CC7? 2) When working with a PCB using the CC3200MOD, how would I flash my Energia sketc

Hello guys i wrote a simple code with a intrerupt on button 2 on MSP430F5529 when i hit the button 2 int should save in flash but when i disconect my microcontroler the variable reset please help me. #include <Wire.h> #include "LiquidCrystal_I2C.h" #include "MspFlash.h" #define flash SEGMENT_D #define flash1 SEGMENT_C byte address = 0x27; // LCD I2C address int columns = 20; // number of columns on LCD int rows = 2; // number of rows on LCD LiquidCrystal_I2C lcd(address, columns, rows); int i1=20; int *pi1=&i1; int i2=0; int *pi2=&i2; int i11=30;

Hello guys i'm working on an application where i need to save 2 float numbers in flash memory (i need them when the msp lose power) ,i have the hardware part done but i can't figure out the coding i'm very new to programing. I need to do something like this. int sensorPin = 23; int sensorValue = 0; float volt; // loop part sensorValue = analogRead(sensorPin); unsigned long currentMillis = millis(); timp=currentMillis/1000; if(currentMillis - previousMillis > interval) { previousMillis = currentMillis; volt=sensorValue; volt=(volt*3.3)/4096; volt=vol

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

Does anyone have any code examples, experience, or can point me to the right direction when it comes to reading/writing to the internal flash that comes with these boards in Energia? I'm wanting to store up to a maximum of a days worth of non-volatile 3x32 bit 5 minute samples (3,456 bytes), before sending as packets when the Rx is in range. Thanks in advance!

Hi, I am currently working on a code in Energia that will allow me to upload and send a binary file wirelessly from a client site to the CC3200. So far, the code has successfully accomplished the following: -the board establishes a Wi-Fi network -commands from a laptop can interact with the board (the Energia Simple Wi-Fi Server example (LED ON/OFF) code was tested to ensure this was working) -a 9 byte binary file is sent through Wi-Fi to the board's volatile memory, saved from volatile memory into an on-baord flash memory file, and confirmed by sending it back to the laptop through a -
Hello! I am using Energia to program TM4C123GXL board. The program performs a primitive data acquisition with low frequency and stores it (together with timestamps) as an array in RAM. I would like to store data in EEPROM or, preferebly in FLASH. Micro-controller has 256kB flash. How can I save data there? There is flash API (flash.h and flash.c) in lm4f/driverlib/ though I am not sure even at which address range I can write/erase data? Can anybody point out to a working example? thanks for help!

Hi, I'm currently developing a software for the MSP430F5510. It worked fine with my development PCB for months, but as soon as I tried it on another one, I got very strange issues. My software is writing text to a display with a built-in font, and I'd sometimes get missing pixels, or the text "dEbug" or "debuf" instead of "debug". I then simplified my code until I arrived at this: #include <msp430.h> #include <string.h> #include "driverlib/MSP430F5xx_6xx/ucs.h" static const uint16_t flash_data[] = { 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF

Can anybody tell me what is importance of EEPROM,Flash,Rom memories in tiva c launchpad ??Other is that we can write EEPROM,Flash in tiva c launchpad so what is use of this means we can write where we can use it?

Hello All, I am trying to write data into flash which i need to copy it to the SRAM later. I am doing this in assembly and this is part of the code i am trying to use. I have provided the addresses of the FMD, FMA and FMC registers needed for flash programming and then I am copying those addresses into the registers r8,r9 and r10. My question is how do i now load data values into the addresses pointed by the registers r8,r9 and r10? As you can see, I am clearly wrong somewhere and need assistance!! FMD EQU 0x000000AB FMA EQU 0x000000DC FMC EQU 0x000000FF . . . . . . LDR

Hi, I'm using the Stellaris Launchpad as part of sequencer/sampler musical instrument that I'm working on right now. I use the internal flash to record and store a couple of short 1-sec clips of audio, sampled at 21kHz - 12 bit. With the FlashProgram() function of the peripheral driver library, I store two words or four samples consecutively, so: record 4 samples - write to flash - record 4 samples - write to flash - etc. The recording happens on a timer interrupt, however the program skips an interrupt every 4 times, exactly when FlashProgram() is doing its thing. So I dove in the FlashProg

I do have a developer working with me, but he is away for a while, and I have been trying to resolved a flash issue we have been having. I am completely stumped. Any thoughts would be welcomed. All values being stored are integers. Using a 430g2553; I can read flash just fine (we had loaded flash data onto the mcu much much earlier in the development path) - here is an example: int *pflash = ( int *) 0x1000; // pointer into data flash settings.checkPumpTurnedOnDelay = *pflash++; settings.pumpOnTestDelay = *pflash++; settings.longSleepDelay = *pflash++; settings.pressure

To know the FLASH and an estimate of the RAM used, find the location of the size utility /Applications/Energia.app/Contents/Resources/Java/hardware/tools/msp430/bin/msp430-size compile a sketch and find the location of the elf file
