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

Hi all, I am new to the forum to MCUs and to energia. I have the TI Launchpad MSP430G2553 with a maximum of 16,384 bytes of available ram as far as I understand. The program below compiles at 3,061 bytes if I use the data type "byte" for my large array, but apparently I am missing 72 bytes of space if I use the data type "int" which if I understand things well is only twice the size of a byte. Can someone explain to me why I get this error? P.S: Some variables are not yet used I know, but they will be int dot = 0; int dash = 1; int empty = -1; int unit = 50; int dot_u

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

Hello all, I have few concepts which I need to clear! Please provide your important experience and knowledge. I keep on reading different controllers with different ratings of flash memory and SRAM. MSP has FRAM. Queries; 1. Usually flash memory is usually much larger than SRAM, because of cheaper price? 2. I know that prog is stored in flash and variables in SRAM. But the variable can be stored in flash also. right? 3. I know that FRAM is faster, less power consuming, longer life than flash.. Only MSP has this FRAM technology right? I know that most of the ARM controllers to

I am using embedXCode+ on a Launchpad MSP430 I am trying to use arduino-menusystem: https://github.com/jonblack/arduino-menusystem. The MenuSystem.cpp uses realloc(). While this works fine if the board is Arduino Uno, I get a "not declared in this scope" when building for the Launchpad. Is there a better dynamic memory allocation routine to use when writing for the Arduino IDE? OR advice on how to fix this? (thank you)

HI, i'm using MSP430FR5969. i would like to better understand how its 64KB memory is organized. From it's datasheet (http://www.ti.com/lit/ds/symlink/msp430fr5969.pdf - pg 23) : Memory (FRAM) Total Size 64KB interrupt vectors 00FFFFh

Hi people! Basically I'm writing a function to control a 16x16 RGB LED matrix with serial communication. The function I'm writing requires an array of size 16x16 ( hueBuffer[16][16] ) and of type 'short' since the max value of hue is 359. However, I keep getting an error: "program will not fit into available memory. run placement with alignment fails for section "DATA_GROUP" size 0x23d" but there is plenty of memory on the G2553. I need the values of hue to go up to 360 so i cant use unsigned chars. Anyone know of a solution to this problem? I'll post the code if you wa
