DrWizard 5 Posted March 23, 2014 Share Posted March 23, 2014 Hello, I am a long time Arduino user, and I was tempted by the $20 price on the newest "Connected" launchpad TM4C1294XL. Seemed mighty powerful for the price! So I am basicly a noob only when it comes to this platform, and I've been going thru the tutorials and 'getting started' videos and I'm still stuck. First of all, I am trying to get started and the "Blink" example does not work on this board. Apparently because whatever I/O pin that Energia maps as "RED_LED" is not the same as any of the I/O pins that drive the 4 LEDS on my TM4C1294XL board. According to the docs for my board, the LEDs are connected to GPIO pins PN0, PN1, PF4, and PF0. This board has a heckuva lot of I/O pins. How are they all numbered/named in Energia? I've tried all sorts of numbers and names and either it doesn't compile because it's not recognized, or it compiles but the lights don't actually blink. It apparently uploads as it seems to have overwritten the Exosite demo app that came pre-loaded on the board. Likewise, I can't get the "Hello" example to work either. No text is received in the terminal. Checked baud rate, com port, hit reset, etc. And likewise, I can't get "Blinky" or "Hello" to work in Code Composer either. No errors that appear fatal. At this point, I'm not sure if my board even works. I have not been able to get either the blinky or hello world sketches to work, either in Energia, or Code Composer. I'm not entirely sure the sketch is even being uploaded to the board. But the Exosite app worked before I apparently overwrote it. I don't see any fatal errors. Like I said, I'm a noob to this platform, but pretty good with Arduino, I've been working with it for years. (Stellaris virtual COM drivers are installed, Windows Device Manager sees my board as COM4) WizBlink.ino Quote Link to post Share on other sites
