No sé desde hace cuanto que el IDE Energia soporta la placa LM4F120, pero el caso es que ya lo hace!
Energia es un fork del IDE de Arduino, tiene la misma interfaz pero en vez de ser para placas de Arduino con microcontroladores Atmel, es para placas con chip de Texas Instruments, las mismas que prácticamente regalaban hace poco mas de un año y que apenas use por lo «engorroso/complejo» que eran de usar en comparación con Arduino.
Se usa igual que el IDE de Arduino, desde Tools > Boards, se puede seleccionar la placa que se quiera programar, y desde Tools > Serial Port, se elige el puerto de la placa.
Después solo queda cargar el código y darle a grabar. Con el siguiente código de ejemplo se hace un Blink RGB

void setup() { pinMode(RED_LED, OUTPUT); pinMode(GREEN_LED, OUTPUT); pinMode(BLUE_LED, OUTPUT); } void loop() { setColor( 255, 0, 0 ); // Red setColor( 0, 255, 0 ); // Green setColor( 0, 0, 255 ); // Blue setColor( 255, 255, 0 ); // Yellow setColor( 80, 0, 80 ); // Purple setColor( 0, 255, 255 ); // Aqua } void setColor(int red, int green, int blue) { analogWrite(RED_LED, red); analogWrite(GREEN_LED, green); analogWrite(BLUE_LED, blue); delay(1000); } |
Este otro código además de cambiar el color del led RGB lo hace con efecto PWM subiendo y bajando el brillo.

/* Fade RGB LED Smoothly through 4 colours Fades an RGB LED using PWM smoothly through 4 different colours pausing for 1.5 seconds on each colour. Connect an common Cathode RGB LED with appropriate resistors on each anode to your Arduino Uno; Red to pin 11, Green to pin 10, Blue to pin 9, Cathode to GND.
