  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
  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.
  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
  5. 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
