  1. So I'm working on a fingerprint scanner project with this repo written for arduino for the scanner I'm using. When I try using this library in Energia, it's been giving me a ram error and refuses to compile. I know that pin assignments and certain things are different between using Arduino to program an atmega microprocessor and using Energia to program an MSP430G2452 with a launchpad, but just compiling it without uploading shouldn't change anything. Here are the errors I'm getting when I try to compile the enroll sketch (attached below) -enroll.cpp.elf section `.bss' will not fit in region `ram' -`ram' overflowed by 50 bytes I've already had to fix a bunch of errors and file imports switching this over to Energia, but now I've hit a brick wall and I have no idea how to fix a problem like this. If anyone could help me with this, I would greatly appreciate it!!! enroll.ino

    Energia for Cubesat OBC board

    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.
  3. While I was reading through the MSP430's User's guide, I came to know that its stack pointer is alligned to even address. (Read Pg.189 of http://www.ti.com/lit/ug/slau208m/slau208m.pdf) Question 1: Why is it so ? Why is the stack pointer alligned to even address? Using msp430-gcc, I wrote a C program which contained a global 'char'(8 bits) array and which will print on UART the address location of each array element. What I found was that each array element was at '+1' from the previous address i.e Address of a[0] is 2400 Address of a[1] is 2401 Address of a[2] is 2402 Address of a[3] is 2403 Question 2: Here I can see that all array element's are not alligned to even address i.e a[1], a[3] are at odd address. Arrays are stored in RAM and are accessed via stack pointer. How did the stack pointer store an odd address ? As per my understanding, each address location in RAM can store 16bits of data(since MSP430) irrespective of even or odd address location. If I write the same above program with 'int'(16 bits) instead of 'char'(8 bits), then I get the array address '+2' i.e Address of a[0] is 3400 Address of a[1] is 3402 Address of a[2] is 3404 Address of a[3] is 3406 Question 3: But my above experimentes showed that each address can store only 8 bits instead of 16. Why ?
  4. the ir library included in energia when compiled gives the following errors : c:/users/chirag/downloads/compressed/energia-0101e0011-windows/energia-0101e0011/hardware/tools/msp430/bin/../lib/gcc/msp430/4.6.3/../../../../msp430/bin/ld.exe: IRtest.cpp.elf section `.bss' will not fit in region `ram' c:/users/chirag/downloads/compressed/energia-0101e0011-windows/energia-0101e0011/hardware/tools/msp430/bin/../lib/gcc/msp430/4.6.3/../../../../msp430/bin/ld.exe: region `ram' overflowed by 62 bytes collect2: ld returned 1 exit status i have updated energia tried changes in the cpp files as well Still the same error occurs >please help me resolve this error its urgent

    FLASH and Estimated RAM Usage

    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
