  1. I'm assuming all energia needs is the library for this board to work correctly, right? Sent from my SGH-T889 using Tapatalk
  2. I was incorrectly connecting the positive lead of the load to the source rather than the drain. I realize a 60 watt MOSFET is overkill. I purchased that specific one by recommendation since I wasn't familiar with semiconductors yet to know one way or another. Anyways, next week this is being launched in a rocket to go a couple thousand feet! I'm excited! Thanks for helping me understand! @rocket4kids I had to do what you said as part of my troubleshooting because I was thinking the same thing. Thanks for the suggestion.

  3. http://www.mouser.com/Search/m_ProductDetail.aspx?Fairchild-Semiconductor/RFP70N06/&qs=taDQNAOcNDFJEU9z22sxLw== I am using this MOSFET to switch a 9v 50 mA circuit to light an e-match and some gunpowder. I'm using the msp430 as a timer after a couple seconds to send the signal to the MOSFET to drive the ematch circuit. The msp430 doesn't seem to be flipping the switch. Any ideas on how I could ignite an e-match with a signal from the msp430? These ematches are rated to burn at 40 mA. I'm using Windows 7, ccs 6.0, msp430 2553 and a 9v to power msp430 and light the match. I
  4. Well, I'm not sure that I copied it into the correct folder then. The bmp085_t.h file I copied into the "libraries" folder and tried to call it but it didn't like that. I'll go over adding files correctly to energia again. Sent from my SGH-T889 using Tapatalk
  5. I used the ReadSensor.ino file included in the github zip file for this library. /* ReadSensor - Basic example of using I2C-based template library for Bosch BMP085 digital pressure sensor. Created by Adrian Studer, April 2013. Distributed under MIT License, see license.txt for details. */ #include <Wire.h> // required by BMP085 library #include <C:/Users/Pat\Desktop/rocket stuff/energia-0101E0011-windows/energia-0101E0011/libraries/BMP085_t.h> // import BMP085 template library BMP085<0> PSensor; // instantiate sensor, 0 = low precision pre
  6. Launchpad 1.5 msp430G2 2553 Bosch BMP085 from sparkfun (no links provided since this is Energia lib problem I think using latest Energia 0101E0011 Windows 7 code provided by OP I tried searching for this error and nothing came up. Did I miss something? I downloaded the files, uploaded them to the Energia folder "libraries" folder I created, copied the libraries from the Arduino software, and uploaded the example file. This is the error code I get: c:/users/pat/desktop/rocket stuff/energia-0101e0011-windows/energia-0101e0011/hardware/tools/msp430/bin/../lib/gcc/msp430/4.6.3/../../../..
  7. I love this forum! Sent from my SGH-T889 using Tapatalk
  8. Hey guys. I'm an EE student at BYU-Idaho located in Rexburg, Idaho. I just finished a microprocessor based systems design course that used the 430 with the 2553 chipset to build a little gameboy with a joystick, LCD, and a few buttons. It was a lot of fun! I was working on a flight computer during the same semester and was using the BeagleBone Black but fried it. I decided the msp430 would be much more appropriate for use in my application, although I've been using 2 due to lack of program space to handle all 3 sensors. I have a BMP085, ITG-3200, and an accelerometer as sensor data in
  9. I must have been doing something wrong because it is working for me now. The TX and RX interrupts were what I was looking for. You commented: // interrupt pragma is defined in grace If grace only sets up hardware, what is the interrupt handling that is defined in grace? (line 329 of the mian.c file) I appreciate you answering! This is great! I'm so excited to wrap my head around this stuff!!
  10. CCS was complaining about the Grace file. Was there any special configurations I needed to see the Grace set up? Specifically I wanted to see the TX interrupt functions. I'm using the same MSP430 2553 chip and BMP085 for a project of mine and was using your code to compare against what I thought I understood. I've downloaded your files but couldn't configure the Grace files correctly so that it would compile for me. Thanks for your help!
