Basically it's something like this:
 

 
In this way you can "switch" the pins for HW or SW UART by just rotating the two jumpers.

Short answer: yes. You will notice the same behaviour if you tie the pin to vcc. Just do some averaging of lets say 10 values and you will get much smoother results.
 
Long answer please see here: http://www.st.com/web/en/resource/technical/document/application_note/CD00004444.pdf

You could just format your serial output as comma separated values (or semicolon or tab or ...) and copy/open these lines to/in excel . That's an easy way I use all the time to e.g. display sensor data in excel. Of course you have no "real time" processing and visualisation of your data - it is just post processing.


Edit: you could also use a VBA script inside Excel to read the COM Port ....

Edit2: PLX-DAQ should work with Launchpad too ... http://robottini.altervista.org/arduino-and-real-time-charts-in-excel
 ... just use the Sketch from there as a starting point

Hi
 
PLX-DAQ works as expected .... so just check your COM-Port settings. I only had to change the COM-Port to a lower number in the Device Manager for my Launchpad since the PLX-DAQ plugin only has Ports 1...15 available for selection.
Anyway ... nice piece of software, I think it could be helpful for future projects.
 
Maybe check this instructable, too - maybe you just missed a step? But I think it's just the wrong COM-Port or Baud-Rate. Launchpad only supports 9600 !!! (see my adapted sketch and PLX-DAQ-Settings)
 

The links and code provided are ment to be used in Energia. Place the library files as mentioned before and copy the sketch-code into Energias coding window ...

Thanks for the results @@reaper7 but credits for code and sketch go to someone else ;-) but good to know it is working as requested by the thread starter ...

@@yosh - Your code works OK with only one mod because my module have "hard" set address 0x76, so I change bme.begin() to bme.begin(0x76)
 

nice i useful, I got my bme yesterday, so first test today

Hi
 
have a look on datasheet pages 37..39 for the pinout (I2C or SPI) and
here https://ae-bst.resource.bosch.com/media/products/shuttleboards/BMP280_Shuttleboard_Flyer.pdf for the corresponding pins on the "shuttel board"
 
MSP432 Launchpad pin map here: http://energia.nu/wordpress/wp-content/uploads/2015/03/MSP432-LaunchPad-%E2%80%94-Pins-Maps.jpg
 
Arduino example + code here (if you plan to use Energia): http://www.seeedstudio.com/recipe/257-bosch-bme280-1-chip-temp-humidity-pressure.html(<- you don't need the level shifter!)
 
additional information, sketch, etc. here: http://cactus.io/hookups/sensors/barometric/bme280/hookup-arduino-to-bme280-barometric-pressure-sensor

Your debounce time would be 1000 ms.

Hi! - I don't know how to help You,
a good choice is to buy a simple logic analyzer.
 
Do You have any message on serial console?
Try to "enable" debug message from lib -> EtherEncLib.h change DEBUGLIB value from 0 to 1 (line 40)
 
You must know how to check process step by step,
simplest method is inserting something like this Serial.println("i'm here"); in different library places (like begin, available etc) called from sketch.
 
You must be like a Herlock Sholmes

Did you check if there is a short in your circuit?

@lessarlz - ENC28j60 is a spi device, so connection is very simple
for eg. if You are using MSP430G2553 board:
 
ENCpin   MSPpin
Vcc          PIN1    +3.3V
GND        PIN20  GROUND
CS           PIN10    P2_2  (you can change this pin in file enc28typedef.h - line 424, then also mandatory! in sketch pinMode(10,OUTPUT);
RESET    PIN16  RESET
SI             PIN15  P1_7 (MOSI)
SCK         PIN7    P1_5 (SCK)
SO           PIN14  P1_6 (MISO)
--
WOL, INT, CLKOUT -> not connected

@lessarlz - sorry...my mistake...wrong platform
for MSP CS pin is PIN10 P2_2...
try to change hardware connection(move wire from msp pin5 to pin10) and change uart speed to 9600 for msp430
