Controls for the microcontroller LEDs on satellite boards.
Requires SCHED_SPEED to be accurately defined in khz.
Example Hardware and Register setup for the LEDs:
// *********************************************** // Heartbeat Init Section // *********************************************** //On-board LED initialization PINSEL2 &= ~(1<<3); // set trace port for GPIO use (bit 3 = 0) FIO1DIR |= (1<<23); // set P1.23 to be output (Green LED) FIO1DIR |= (1<<24); // set P1.24 to be output (Red LED) FIO1DIR |= (1<<25); // set P1.25 to be output (Blue LED) MCU_LED_ALL_OFF;
