Name ---- saa10*** Overview -------- Proprietary kernel module used to control the front panel LED display Associated Device(s) -------------------- /dev/saa10*** Parameters ---------- debug : Enable additional debug output [default 0] scroll_enable : Enable scrolling (0-1) [default 0] scroll_forwards : Scroll forwards (0-1) [default 1] scroll_delay : Scroll delay in milliseconds [default 500] display_brightness : Display brightness (0 - 7) [default 4] Description ----------- This module is used to control the output of the front panel LED display. The display consists of four 7-segment displays each with a dot. The LEDs can display alpha numeric character strings (up to 256 characters) which can be scrolled at variable speeds through the display. Updated display strings can be sent to the display by writing to the device. All of the device control is achieved using IOCTL commands listed below. Note : Due to the limitations of a 7 segment display some characters cannot be displayed. For a worked example see exStbLED IOCTLs ------ SAA10***_IOCTL_SET_SCROLLING_ENABLE : Enable / disable scrolling SAA10***_IOCTL_GET_SCROLLING_ENABLE : Get the scrolling mode SAA10***_IOCTL_SET_SCROLLING_DIRECTION : Set the scrolling direction SAA10***_IOCTL_GET_SCROLLING_DIRECTION : Get the scrolling direction SAA10***_IOCTL_SET_SCROLLING_DELAY : Set the scrolling delay SAA10***_IOCTL_GET_SCROLLING_DELAY : Get the scrolling delay SAA10***_IOCTL_SET_DISPLAY_BRIGHTNESS : Set the display brightness SAA10***_IOCTL_GET_DISPLAY_BRIGHTNESS : Get the display brightness Associated files ---------------- comps/saa10***/inc/saa10***.h apps/exStbLED/src/exStbLED.c
