6.2. Buzzer for KS8695 based Devices

The OnRISC provides a buzzer for acoustic signaling. You can manipulate it via the IOCTL-calls

or via the Proc-Filesystem. Following IOCTL commands are deﬁned in the onrisc.h to control the

buzzer:

• GPIO_CMD_GET_BUZZER/GPIO_CMD_SET_BUZZER - turn on/oﬀ the buzzer

(reﬂected in /proc/vscom/buzzer)

• GPIO_CMD_GET_BUZZER_FRQ/GPIO_CMD_SET_BUZZER_FRQ - get/set the modulated signal de-

lay. So that the buzzer will be turned on for the delay speciﬁed and the it will be turned oﬀ

for the same delay and so on till this mode will be turned oﬀ

(reﬂected in /proc/vscom/buzzer_frq)

6.3. LEDs for KS8695 based Devices

The OnRISC provides three conﬁgurable LEDs:

• red LED (power LED)

• blue LED (can be used to signal WLAN link)

• green LED (user LED)

• WLAN button LED (OnRISC Alekto LAN only)

Following IOCTL commands are deﬁned in the onrisc.h to control the LEDs:

• GPIO_CMD_GET_LEDS/GPIO_CMD_SET_LEDS - get/set LED combination

(reﬂected in /proc/vscom/leds)

• GPIO_CMD_SET_LED_POWER - turn on/oﬀ the power LED

• GPIO_CMD_SET_LED_BLUE - turn on/oﬀ the blue LED

• GPIO_CMD_SET_LED_GREEN - turn on/oﬀ the green LED

• GPIO_CMD_SET_LED_BTN_WLAN - turn on/oﬀ the WLAN button LED (OnRISC Alekto LAN

only)
