Hardware Access Functions

These functions allow you to directly control aspects of the Smart Multibox hardware

multibox_blink_led()

Turns the LED off for a short period of time (~50msec), then returns it to its previous color. This routine is regulated so that blinks are only allowed to happen at a certain rate. This prevents the LED from being off all the time when this routine is called frequently.

multibox_set_led(color)

Sets the LED to a specific color. Possible color values are LED_OFF, LED_GREEN, LED_ORANGE and LED_RED.

multibox_set_trs_mode(mode)

Sets the operating mode of the TRS port. Valid values are TRS_EXPPEDAL (enable expression pedal mode) and TRS_EXTSWITCH (enable external switch mode). The default at power on is TRS_EXPPEDAL mode.
