  1. Hi, I am trying to modify some of the core Energia files (main.c) so that I can initialize GPIO pins to LOW right away before Energia goes through its startup sequence. I have an LED driver connected to the MSP430FR5739 experimenter board (v1.1). The issue is, during the startup sequence (before my setup() code is running) the control pin from the experimenter board to the LED driver is active high for a few seconds thus turning the LED to full brightness. I would like to avoid using an external resistor if possible. My question is: 1. Is there a better way to initialize GPIO pins in Ener
  2. Hi, I want to use Energia to program my MSP430FR5739. I have used the 34 pin variant which has two pins that are not on the dev board - P2.3 and P2.4. I am using these as analogue inputs. I found another post which indicated that I could edit the pins_energia.h file with the following lines static const uint8_t P2_3 = 31; static const uint8_t A12 = 31; Which should, on the face of it, get P2.3 working, but no success... Any help would be appreciated!
  3. Has anyone experienced issues with the msp430FR5739 experimenter board with the latest energia v 18? I can't seem to program it using the latest version on my windows 10, 7 or mac. I get the following error message: usbutil: unable to find a device matching 0451:f432 An error occurred while uploading the sketch Thanks!
  4. Well Hi! I'm reasonably new to the MSP430 stuff, been working with Arduino's and started some Embedded systems unit at University that has really sparked an interest in this stuff. I've been working mainly in Energia but trying my best to explore whats under some of the abstraction. Currently exploring CCS environment. Looking forward to sucking up some of this communities knowledge and hopefully providing some of my own as well
  5. I'd like to write to FRAM on a MSP430FR5739 with Energia, Does anyone has an example? Thank you, Stephane
  6. Hey all, just wanted to share some code and a sweet picture of a QR code that was generated on an msp430fr5739: I'm working on a larger project that needed this functionality so I thought a proof of concept before I got too far into this was in order. While the pixels on the LCD I'm using (Nokia 5110 / PCD8544) aren't quite square, this code scans fine on my phone (Nexus 4). Anyways it uses the qrduino library to generate the code and some pcd8544 library for the lcd display. I briefly attempted to get this running on a g2553 but didn't quite manage it. The code is at https://
  7. I recently bought a Fram board and a CC3000 for a small project. I have Code Composer already but wanted to try somthing new and ran across Energia. So I installed it and fired it up. I selected CC3000FirwareUpdate project to get started. Selected the FraunchPad w/ msp430fr5739 board in the Tools menu. Then I hit the Verify button... "Error compiling." c:/energia-0101e0011/hardware/tools/msp430/bin/../lib/gcc/msp430/4.6.3/../../../../msp430/bin/ld.exe: CC3000FirwareUpdate.cpp.elf section `.rodata' will not fit in region `rom' Regards Ken
  8. Hi, I was trying to run simple web client code example in energia (MSP-EXP430FR5739 + CC3000). In the code, we have to set communication pins for CC3000 (CS, EN and IRQ pins). From the wiki page (http://processors.wi...-Fi_MSP430_FRAM), pins on FRAM associated with these functions through RF connector are pin 1.3, 4.1 and 2.3. So I tried to find out the pin numbers to use in the code for these pins. But in the default pin mapping for fraunchpad, pin2.3 is not defined (The pins defined in pin mapping seem to be correct). Is there a pin mapping specifically for MSP-EXP430FR5739 which would

  10. Hi all! I recently worked upon a weather station project where we were required to display the data on a website. I finally decided to create a web UI for MSP430FR5739 launchpad as well. The web UI is created using Node.js for the server end. The graphs update at every 100ms period. For testing online, i have used localtunnel which allowed me to convert the intranet to internet. The UI receives the data from a MSP430FR5739 launchpad and the data is then displayed on the website. Also, you can transmit data from UI to the launchpad as well.

  11. I finally did a breakout for the msp430 chips that use the tssop-38 pin layout. I made it generic so it can be used with various chips. The layout makes no assumption about power or the SBW pins. There are a couple of vias that could be used for a LFXTAL or decoupling caps. Just drag a wirewrap gauge wire to the right pin.

  12. hi all i have msp-exp430fr5739 kit and i learning i want an example code of module on kit Vietnam and I was struggling to learn the language line mcu.
  13. As of now I am getting a result, but I don't think I'm getting the right result. My pressure result is at 236055 in a lab room. I wondering if someone can check out my code to see if I'm doing something wrong. The following is the datasheet of the bmp085: http://dlnmh9ip6v2uc.cloudfront.net/datasheets/Sensors/Pressure/BST-BMP085-DS000-06.pdf #include <msp430.h> //unsigned char TXData[]= {0x07,0xB1,0xA1};// Pointer to TX data //unsigned char TXData[]= {0x00};// Pointer to TX data //unsigned char SlaveAddress[]= {0x5A,0x27,0x77}; //temp, humidty, pressure unsigned char SlaveAddre
