  1. You'll need to modify your startup_gcc.c under "(...)\hardware\lm4f\cores\lm4f\". I'll attach mine, already modified with SysTick interrupts enabled. After that, you'll need to declare in your main program another function besides setup() and loop, called "SysTickIntHandler()". Inside that function, put the code you desire, and voilà. //***************************************************************************** // // startup_gcc.c - Startup code for use with GNU tools. // // Copyright (c) 2009-2012 Texas Instruments Incorporated.

  2. I've had the same problem using the PWM outputs. My solution was, instead of including the TI microcontroller header (wich causes many crashes under Energia), to search in the original TI header for the pin and name used and #define it manually. Worked as a charm!
  3. Yes. gpio.h uses pin_map.h, which has no declaration of these pins for StellarisPad (at least in energia). I took those #defines directly from TivaWare C Series 1.1 pin_map.h. It seems to work for Tiva pads.

  6. Hello, everyone! I'm from Rio Grande do Sul, extreme south of Brazil, and came here searching about Energia and Tiva C. I have a large experience using PIC microcontrollers, but I'm a fresh new student to TI/ARM hardware. Will be around here, reading every topic. It will take a while
