  1. Hello all! So, this is happening on BOTH my Ubuntu 16.04 AND Windows 8.1 systems. This is for a TM4C1294NCPDT. To reduce potential variables, I've reverted to using the EK-TM4C1294XL Development Board. To reproduce: Fresh install of CCSv7.1, Fresh install of Energia 18. Open CCSv7, Create a new workspace, select 'Project > New Energia Sketch', Energia Version set to 18, select 'Built-in Examples > 01.Basics > Blink.ino', selected device: 'LaunchPad (Tiva C) w/ tm4c129 (120MHz), select 'Finish'. Right Click 'Blink" project in the Project Explorer, select "Build Project'. Project builds fine. Push F11 (or select 'Debug Blink' from the toolbar). Code is uploaded, but the debug 'Resume' button is grayed out. LED does not blink. Note: 'Blink' runs fine in the Energia IDE itself. What happened in the update to CCSv7? I'm taking a shot in the dark here, but I think the memory map is b0rked. If I disable "On a program load or restart" in the 'Debug > Auto Run and Launch Options' and then attempt to debug, CCS starts the debugger at "void ResetISR(void) {" in startup_gcc.c. See attached image for disassembly view. I think (IIRC) that the two ldr calls in assembly are usually right below that 'push', but my memory ain't what it used to be. Anyhow, if I try to 'Step Into' with F5, I immediately get a dreaded "No source available for "0xfffffffe" ... So, any idea what the hell happened? This shoots me dead until this is resolved... I figured TI would at least test Energia GCC debugging before releasing v7, though I do tend to err with my assumptions quite often. If you need anything, just holler. EDIT: For posterity, here's my TI E2E forum post on the same: https://e2e.ti.com/support/development_tools/code_composer_studio/f/81/t/586137
  2. Hello I hope you can understand my english I have a texas instruments tm4c123gxl with a SainSmart IIC/I2C/TWI Serial 2004 20x4 LCD Module. I will connect this Display over I²C. For the 5V Supply voltage i have use the VBus on the tm4c... For the SDA/SCL i have use the pin PA6 and PA7. Does it work like this? or need a Logic Level Converter - Bi-Directional for the SDA/SCL Line? from 3,3V to 5V. I have use a Pullup resistor for the Line SDA/SCL, how in the datasheet from the tm4c. And i have use this Code: #include <Wire.h> #include <LiquidCrystal_I2C.h> LiquidCrystal_I2C lcd(0x3F, 20, 4); // set the LCD address to 0x20 for a 16 chars and 2 line display void setup() { lcd.init(); // initialize the lcd // Print a message to the LCD. lcd.backlight(); lcd.print("Hello, world!"); } void loop() { } But my display show nothing only LED backlight.
  3. Is there a way to use the SoftwareSerial library on the Stellaris Launchpad TM4C123GXL board? I am trying to connect a Sparkfun serial enabled LCD screen to the board but the SoftwareSerial library is only compatible with 20, 16, and 8 MHz processors, and the TM4C123GXL is an 80 MHz chip. How can I use this LCD screen with the Stellaris Launchpad over a UART connection? Do I need to use SoftwareSerial or can I do without it? I am programming in Energia 0101E0017 on Windows 7 64 bit. Any help is greatly appreciated, thanks!
  4. Hi to all out there, I've started development on the Tiva TM4C platform using the very nice LaunchPad two years ago. Since then I had so much fun to create cool applications and even complete systems based on that awesome low cost Ecosystem . During my projects I realized that there is not really a BoosterPack that turns the LaunchPad into a modern audio player/recorder. Because of that I've started to develop a BoosterPack named BoostMP3 that will enable any LaunchPad to work as a cool multipurpose audio device. For that I've created the following little lading website that gives a short introduction on that. http://labvenue.jimdo.com/ Since I'm not so good in Sales or advertisement I was thinking that the best way to get any kind of feedback would be to ask all you people out there. Is there any kind of interest to buy this? Is the offered functionality ok or would you like to have more or less? What do you think about the price?? I would appreciate any kind of feedback! Thanks a million!
  5. Got an email today about a new LaunchPad supporting hardware cryptography - mainly aimed at supporting HTTPS for your IoT projects. Promo pricing $16.99, normally $24.99. http://www.ti.com/tool/ek-tm4c129exl
  6. I am confused about the compatibility of BoosterPacks. According to the TM4C123 pub spmu296.pdf: * The TM4C123 is compatible with the "TIVA C Series LaunchPad BoosterPack XL" * The outer column of pins are also compatible with MSP430 "LaunchPad-Compatible BoosterPacks" In the TM4C129 pub spmu365a.pdf it describes the first and second BoosterPack XL. "‘A’ and ‘D’ make up the outer BoosterPack standard pins, ‘B’ and ‘C’ make up the inner BoosterPack XL standard pins." On examining the pinouts between the 123 and 1294 for these 2x10 pins, none of the pin functions match. How do I identify which boards a BoosterPack will be compatible with? Some BP descriptions say " for the MSP430." Most do not mention compatibility.
