Hello all! I've got three new libraries to share with you! They are: An Arduino "Servo" library clone (StellarPad): Duplicates all of the functionality of the Arduino "Servo" library. Fully compatible with all existing sketches that use the Arduino "Servo" library. Based upon the Eigendreams servo library posted here a while back. Supports 8 servos as-is. Can be modified to do a heck of a lot more, but that is up to you to incorporate (at least for now -- update to come soon). An ultrasonic rangefinder library (StellarPad, easily modifiable to work with other Energia devices): Designed for the HC-SR04 rangefinder, about $5 on e-bay. Should also work with some other rangefinders, but I have not tested any others. That is, again, up to you (for now). Supports as many of them as you can fit on your I/O. A data smoother library (All Energia/Arduino supported devices): Inspired by the Arduino "smoothing" example by Tom Igoe. Allows the creation of "Smoother" objects that calculate running averages of raw data. "Smoother" is a template class and can be instantiated to work with int's, float's, long's, etc. All three libraries have their own examples, and the following is an example that incorporates the functionality of all of them (No comments, sorry! This one is pretty self-explanatory. See the library-specific examples for more details): #include <SonicRanger.h> #include <Smoother.h> #include <Servo.h> SonicRanger sr; Servo servo; Smoother<int, 10> ssmoother; boolean smoothing = false; void setup () { sr.attach(PE_1, PE_2); servo.attach(PF_1); pinMode(BLUE_LED, OUTPUT); digitalWrite(BLUE_LED, LOW); pinMode(PUSH2, INPUT); attachInterrupt(PUSH2, buttonISR, FALLING); } void loop () { float distance = sr.getDistance(INCHES); int processedDistance; if(distance > 0) { processedDistance = (int)(distance * 1000); processedDistance = constrain(processedDistance, 2000, 12000); if(smoothing) { ssmoother.pushValue(processedDistance); processedDistance = ssmoother.pullValue(); } servo.write(map(processedDistance, 2000, 12000, 0, 180)); } delay(50); } void buttonISR () { smoothing = !smoothing; digitalWrite(BLUE_LED, smoothing); } Video demonstration of the above example sketch: http://youtu.be/IViqIa4Rl9Y Enjoy! -K/Fughilli SonicRanger.zip Smoother.zip Servo.zip -
Scheduler/Chron library -- experimental!
fughilli posted a topic in TivaC / CC3XXX Energia Libraries
Hello all! I've been on a sort of coding binge lately... and so a new library has been born! This one will come with basically no manual and no explanation, other than: It lets you schedule things to happen at specific times. It is timer interrupt-driven. It works with the StellarPad. It requires that you make some modifications to startup_gcc.c and (at least, in my case) to Energia.h, main.c, and lm4fcpp.ld. All the files are attached below. Be warned that this is an early prototype, and that though it works (as far as I can tell) now, it will probably undergo some pretty significant changes in the future. Three examples are included. Have fun! -K/fughilli Chronos.zip modified_things.zip -
I tried the ASCII Table demo with Launchpad and it seems to work flawlessly. When I recompile for Stellaris and run on the StellarPad at 9600 baud, it works MOST of the time, but occasionally the serial monitor receives garbled text. I thought it might be a problem with the serial monitor, so I also tried using teraterm with the same results. I am using Energia 0101E0009 under Win7.

I don't have one of these yet, I am still waiting for mine to arrive. My question is this: How many "individual" pins on this board are capable of doing analogWrite? I say individual as on the 2553 while there are 6 pins available, certain pins share the same timer, so you can only use 1 pin out of a "pair" which share a timer. So, that said, does anyone have an answer to this? Thank you! Also, I read somewhere that the pins on this board are 5 volt tolerant, however while reading the datasheet, it looks like that isn't the case. Would be great if I could use this board with 5v logic (even if it is being powered by 3.3v). Can anybody weigh in on that?

I've followed the cdcacm directions and have the MSP430 working with Energia! Well, I can upload Blinky example anyway. But, I can't get the Stellarpad to work. Upon upload I get "No ICDI device with USB VID:PID 1cbe:00fd found! Failed!" error. Linux Mint 3.2.0-23 kernel, fresh install yesterday Energia latest version downloaded and installed today Any suggestions?
