  1. I have an issue when using the Capacitive Sensing Library from Arduino. I used the ver. 5 that allows non-AVR boards to use the library. My problem is when I complied it in Energia, I get these errors: /Users/apple/Documents/Energia/libraries/CapacitiveSensor/CapacitiveSensor.h:94:2: error: 'IO_REG_TYPE' does not name a type /Users/apple/Documents/Energia/libraries/CapacitiveSensor/CapacitiveSensor.h:95:11: error: 'IO_REG_TYPE' does not name a type /Users/apple/Documents/Energia/libraries/CapacitiveSensor/CapacitiveSensor.h:96:2: error: 'IO_REG_TYPE' does not name a type /Users/apple/Docum
  2. Hi All, I am trying to connect MQ-6 LPG Gas sensor to MSP430G2553 launchpad. I am having trouble to interface the sensor to launchpad. From the inernet forums i understood that we can use launchpad TP1/TP3 pins for 5v supply but i am still not clear about the other pins. Can someone help me on the connections and wiring? MQ 6 sensor: https://www.fabtolab.com/MQ6-LPG-propane-butane-sensor Thanks in advance.
  3. Hi all, I've been lurking for a while but I finally joined up! I recently received the MSP430FR5969 FRAM Launchpad with EnergyTrace, and I'm trying to upload code to it with OS X 10.9.4 and mspdebug. I am successfully able to upload code to the standard Launchpad with the MSP430G2553 but I cannot upload to the FRAM Launchpad. Looking at this makes me think that a work around has not been found yet, is this true? Or has someone gotten the new FRAM Launchpads working with OS X? Thanks in advance for any help!
  4. This code example works with Anaren and CC2500 BoosterPacks, (and of course with many other CCxxxx boards, like eZ430-RF2500,) and with G2553 LaunchPad. The code was based on slaa325 from TI (I am using same RF configs.) To use it, just un-comment one of the following lines in msp.h: //#define HARDWARE 2500 // CC2500 BoosterPack SPI1 G2553 LP //#define HARDWARE 915 // Anaren (915MHz) G2553 LP //#define HARDWARE 4302500 // EZ430-RF2500 CCxxxx.zip
  5. Programming a microcontroller for the first time can be a daunting task. What if you can remotely control your microcontroller by simply clicking few buttons on a PC GUI? With Energia support, I was able to port existing Firmata code used for Arduino onto LaunchPads. Firmata is a serial communication protocol that allows a host (PC) sending commands to the microcontrollers (MSP430). You can use it to toggle pins and LEDs, or read digital and analog inputs without writing any C code. This makes it super easy to test out your new sensor or debug your circuit. Bluetooth simply creates a
  6. Hai I'm a complete newbie to Energia and MSP430. I would like to get some help on a problem that I'm facing while interfacing MSP430 launchpad using I2C(it's not "a" problem, rather it is "THE" problem). As mentioned above I'm using a MSP430-g2553 launchpad ver1.5 and currently I'm working on a project that requires interfacing two MSP430s with a Raspberry Pi. The protocol that I've chose is I2C due to it's simple hardware requirement and it's support for many devices at the same time. But then till now interfacing two MSP430s has been a faliture. I tried interfacing two MSPs on two launchpad
  7. 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)
  8. Hi everyone, it is probably a very stupid question. But i'm simply trying to toggle a LED(P1.0) by using the button S2(P1.1) which is on the launch pad of FR5969. but it is not wotking at all... #include <msp430.h> void main(void) { WDTCTL = WDTPW + WDTHOLD; // Stop watchdog timer P1DIR |= 0x01; // Set P1.0 to output direction P1REN = 0x02; ? P1OUT= 0x02; ? P1IE |= 0x02; // P1.1 interrupt enabled P1IES |= 0x02; // P1.1 Hi/lo edge P1IFG &= ~0x02; // P1.1 IFG cleared _BIS_SR(LPM3_bits + GIE); // Enter LPM4 w/interrupt } // Port 1 interrupt service routine #pragma
  9. hi all, i'm using lauchpad v1.5 G2553 chip on it. I'm reading an anolog signal (150 Hz, 0-1.5Volts). The default sampling frequency for example potentiometer reading codes seems too slow. How can i set the sampling frequency to 1kHz using Energia (0101E0012 version) ? Any sample code would be appreciated thanks...
  10. Hi All, I am trying to use the AIR430BoostFCC library using the MSP430G2452 uC on the Launchpad. It appears that the library does not play well with this particular uC. The code will run until I call the Radio.begin() function, at which point it stops. Perhaps this is because the G2452 has a USI SPI interface and not a USCI? The MSP430G2553 seems to work correctly (with USCI), but not the G2452. Previously I had a problem compiling code using the AIR430BoostFcc library, which was fixed but the problem had something to do with the defines for USI SPI. That post is here. Perhaps there ar
  11. Hi, I am just learning to use TM4C123G launchpad with energia. I wanted to use one of my old codes (which used MSP430G2553) on it. The only problem is that the compiler doesnt allow me to use analogReference. The datasheet of the controller doesnt mention any internal voltage reference. Will it be fine if i generate required VREFP on any other GPIO via analogWrite and then connect it with VREFP pin externally? Help!
  12. Hello everyone, FIrst - its not the permission issue of not having a proper udev rule. I am on Debian Wheezy with all the msp related packages installed from the official repos - including mspdebug. But after I connect the launchpad and give: mspdebug rf2500 I get usbutil: unable to find a device matching 0451:f432 My computer is not detecting the board. The output of lsusb is: Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 002: ID 8087:0020 Intel Corp.

  13. I am happy to announce that release 0101E0012 just went up on energia.nu. I want to thank everybody for their support and contributions. Energia would not have been possible without such an awesome community! Details of the release can be found on http://energia.nu
  14. Hi, Quite new to this forum and the Stellaris launchpad. I've faced a problem and not found any answers after hours of searching. I feel pretty stupid about this one, since it should be very basic. I've set up gcc on my linux desktop and have been able to run several examples and tested some of my own code without any problems. I want to do some temperature readings using a DS18B20 temperature sensor. I soldered a temperature sensor to PE4. The problem I face is that everything seems to hang once I set PE4 as GPIO input. I've stripped down my code to make it easier to debug, please
  15. Hi all, I need to make a display with wireless interface. In this case, i use Anaren AIR CC2530, MSP430 Launchpad Value Line, and BCD Display I have succesfully connected my MSP430 Launchpad with ANAREN AIR. It is less problematic there. The problem is when i try to stack the BCD Display to launchpad (without Anaren AIR). It took me 1 week to notice that i need to remove jumper J5 to make the BCD display work. (The BCD display need P1.6 connector to be connected to the pin, not to the LED). After i make that jumper open, the display is now showing the graphics. Now, i need to stac
  16. I got an email about this today - you can order up to 2 Tiva Connected LPs at $19.99 each. Very tempting! https://estore.ti.com/tiva-connected-launchpad.aspx?DCMP=mcu-tivc-ek-tm4c129xl-en&HQS=mcu-tivc-ek-tm4c129xl-em-es-en
  17. This library allows you to quickly and easily connect your LaunchPad project to Exosite's Data Platform in the cloud. It connects your project using a MSP430F5529 LaunchPad and CC3000 BoosterPack. Two software packages are available: the Exosite barebones-template solution and a real-world example in the form of the Exosite BBQ Companion Combination. Both of these use-cases have code available for the Energia and Code Composer Studio IDEs. Present Support: MSP430F5529 LaunchPad Future Support: Tiva C Series TM4C123G LaunchPad Required: CC3000 Wi-Fi Transceiver BoosterPack Optional: ADS1118 B
  18. I created a quick project to start learning nodejs. To those that are unfamiliar nodejs allows you to write javascript for the server side. So I decided to write a small gui that plots serial data. The GUI itself is written in javscript/html and uses node-webkit to package it into a .exe file (or the correct package for your os). This could easily be extended to visualize a lot more I/O from the launchpad, and given that the GUI is written in html/javascript it is really easy to create new elements. Here is the source: https://github.com/zlalanne/node-serial-gui The repositor
  19. .. finally made the switch and flashed OpenWrt to a TP-Link WR703N router, added a 16G memory flash stick, and connected to my first F5529 LaunchPad. Here is a picture of the setup. The version of OpenWrt is 12.09. To connect with the MSP Launchpad, need to install the acm driver by opkg install kmod-usb-acm And also installed "screen" for serial client by opkg install screen Apart from the missing bridge library that come with the Yun, i'm quite satisfied with this setup, especailly the tiny form factor of the whole package. The LaunchPad seems to enjoy running with her new I
  20. Hello everyone. I am a beginner with the MSP430 and need help. I am using MSP430G2452 launchpad and another MSP430G2452 which is on a breadboard. I really just need help getting started. I hooked UART between the two and supplied both with voltages, is this the correct way to set it up or am I missing something? How is the J3 configuration supposed to be? Also, I do not know where to go with the coding. How do I program a simple LED on the breadboard from the second MSP430? Thank you so much in advance!!
  21. Hi! I am new to here. Several months ago I got a Launchpad with two chips 2553 & 2452 inside the box. I am really enjoying it except one thing: They have no LCD driver. Considering an external LCD module will bring terrible power consumption, I wonder if I can drive a simple 3 1/2 digits 7 segments LCD with very little power consumption. After searching the internet I found Maxim's 4 digits decoder ICM7211 might be a choice, but it is hard to access and so expensive that I cannot accept. Another choice is to use BCD to 7 segments decoder, finally I found 4543 BCD to 7 segments decoder
  22. Hi guys! I'm trying to use energia for a simple TX/RX with cc1101 and launchpad + msp430g2452, but i don't know how to use spi to comunicate cc1101 with msp430 in energia interface... can sombody help me? I'am using: Energia 0101E0011 windows 7 (64 bits)
  23. Hello, I tried to use my MSP430G2553 launchpad with a keypad (https://www.sparkfun.com/products/8653) using http://www.pjrc.com/teensy/td_libs_Keypad.html http://bildr.org/2011/05/arduino-keypad/ http://www.instructables.com/id/Using-the-sparkfun-12-Button-keypad-with-the-ardu/ http://www.ti.com/lit/an/slaa139/slaa139.pdf (i just tried schematic with Energia code) http://little-scale.blogspot.com/2011/10/how-to-connect-keypad-to-arduino-simple.html (prints blank lines in same row , buttons doesn't work except 2,5,8,0 and they print "y") #include <Keypad.h> const byte ROWS = 4; //
  24. Hello, I am trying to interface my MSP430G2553 launchpad with an LCD (http://www.winstar.com.tw/UserFiles/ProductImages/12523136510757108108.jpg) but my characters look weird. I am using http://www.fibidi.com/arduino-lcd-16x2-characters/ with one potentiometer , with changing ports like this: #include <LiquidCrystal.h> // initialize the library with the numbers of the interface pins //LiquidCrystal lcd(8,9,4,5,6,7); LiquidCrystal lcd(P2_4,P2_5,P2_0,P2_1,P2_2,P2_3); void setup() { lcd.begin(16,2); lcd.setCursor(0,0); lcd.print("Hel
  25. Hey guys. I recently got a Launch pad -- MSP430G2 board ( Rev B ) [only the board and the USB cable from a friend]. I downloaded Energia for my Mac running OS X 10.9. [maverics]. Though the Power LED lights up, the board is not recognised by the IDE. I don't know if the problem is with the board, the cable or the IDE. Though the board was detected for a short period of time and I was able to just uplaod the Blink sketch into it. Now when I connect to a USB power or my MAC, led1 just keeps blinking. I am unable to program it. I hope you guys can help me spot the problem so that I ca
