Rei - have you used the Nokia 5110 with Energia and the Adafruit GFX library yet? Should this work?

Sounds like a plan. Or even use a small potentiometer to make the value adjustable by the user. I've got 5 of these displays and have found them all to need slightly different contrast values. Thanks again again Rei.

Rei, Thanks so much for your help - that's exactly what I needed. I've included before and after setContrast commands to show you what a big difference it made. (I've set the contrast to 60 in the photo on the right.) Also, I did make some minor changes to that code to get it to compile (just in case anyone else is trying to use it). I had to add a comma and a close parenthesis on each line of the .cpp code, so that it looked like: Again, thanks so much for your quick and accurate reply Rei - your contributions to the Energia and 43oh communities are tremendous.

Rei Vilo, Is there a way to set the contrast with this library? With the Adafruit version of this library, there is a command like: display.setContrast(50);

Yes, Windows. Sounds great!

If you need alpha testers let me know, Energia for Stellaris will be BIG

Are you serious? That would be amazing! :clap:

Is this boosterpack available for purchase anywhere?

Hello Stellarisiti! I'm coming from 43oh.com. Should be receiving my first Stellaris Launchpad in the mail tomorrow or the next day, and I'm looking forward to bugging you guys to show me how to use it. Thanks for starting this board!

Not offended at all - I do stupid stuff all the time, so your questions are relevant. I tried SDA and SCL connected to both 1.6 and 1.7. I have the display powered from the 5V test points near the USB connector on the launchpad. I was thinking of the display's logic being passive and not having to worry about 5V coming back to the Launchpad...but I didn't check. I just measured the voltage on SDA and SCL pins of the display while it's powered up and I'm measuring 150mV, but I don't know if that measurement is valid or not.

1. I have not confirmed this with the Launchpad. The display works fine with Arduino boards, though 2. 2553 3. 14 and 15, or P1.6,P1.7 4. 0x27 5. I am using the library found here (at the bottom of the page): http://www.dfrobot.com/index.php?route= ... GYpGk3A9TI I am just trying to upload the 'Hello World' sketch from that library which is: //YWROBOT //Compatible with the Arduino IDE 1.0 //Library version:1.1 #include #include LiquidCrystal_I2C lcd(0x27,16,2); // set the LCD address to 0x27 for a 16 chars and 2 line display void setup() { lcd.init();

Has anyone gotten this display to work with Energia? http://www.sainsmart.com/module/lcd-mod ... ga-r3.html I'm not having any luck so far with this.

I don't have a scope. I'm assuming the pulses are much to quick for me to capture accurately with my $30 multimeter. Would be nice if someone with an o-scope could check it out.

can you sticky this? I've referred back to this post about 8 times now.

I should have updated this post, but I was successful with getting the HC-SR04 to work with the MSP430/Energia a few weeks ago. http://www.meanpc.com/2012/09/using-hc- ... th-ti.html I did use the 5V pins near the USB connector, but I didn't even think about the voltage on the echo pin - good catch.

So, this makes it sound like you know the answer? On one hand, I figure TI is 100% behind Energia. It's hard for me to find the motivation for people that know how to write code for the MSP-430 to open the microcontroller up to 'non-engineers' for seemingly no gain. So maybe Energia is funded and driven by TI? I don't know the developers of Energia, so this may be way off base. On the other hand, like SeuPay said, there really isn't any money in the hobby market. The money comes when an engineer brings a product to market and orders 1,000,000 micros to build the widgets. But, if y

Does TI support Energia?

Any of you see this at Kickstarter? http://www.kickstarter.com/projects/zacinaction/kicksat-your-personal-spacecraft-in-space?ref=category I saw several mentions of Energia and screenshots in the updates of the Kickstarter.

I'm very appreciative of the work you guys have done on Energia. Has anyone done anything with the HC-SR04 sensor using Energia?

I will definitely learn to program microcontrollers directly without the training wheels some day. For now, I need the training wheels. I'm not an engineer or a programmer, so a spoonfed approach is best for me. I installed and tried out Energia - success! It is good to actually be able to program an MSP430 chip, however convoluted my approach is. That team is doing what TI should have already done, if they want the student/hobbyist market at all. We have to start somewhere right? I find it strange how TI comes out with this awesome Launchpad dev board that seems to be geared to

Just checked out Energia and it is exactly what I was looking for. Last time I tried this, I went looking at EasyMSP and it is apparently dead. I'll hopefully be bugging you guys in the Energia forum now.

Thanks for the replies, I did not even know about Energia. I can program in C, the code examples Ive looked at for the MSP430 ha e looked like gibberish compared to the Arduino sketches I'm used to. Going to give Energia a look, thanks for the advice.

What is the best way for someone that can develop projects for the Arduino to move to the MSP430, assuming that the person does not know Assembly.

I'll buy 3.

bluehash, Thanks for the welcome and yes, that is my blog post.
