Change resolution on daytona borad.

Post by YongSung Yoon » Sat Feb 08, 2003 7:46 am

Guys,

I'm using QNX 6.1.0A on Daytona Board(XScale).
There is 'devg-cotulla.so' for graphics drivers.
Our daytona has 640 X 350 LCD screen.
And 'cotulla.conf' describe our screen properties like below.

I want to know how I can change screen to other resolution mode. (ex more
smaller resolution.)
Can I do it though changing contulla.conf ?
If so, is there anyone who teach me how I can ?

If not, Should I change 'devg-cotulla' driver ?
'devg-cotulla.so' is included in Xcale BSP on prebuilt binary.
Where I get the source code of 'devg-cotulla.so' ?

Any idea ?

File 'cotulla.conf'.
# devg-cotulla.so parameters for tailoring to specific boards and display
modes.

# hsw Horizontal Sync Width
# elw End-of-line pixel clock wait
# blw Beginning-of-line pixel clock wait
# vsw Vertical sync pulse width
# efw End-of-frame line clock wait count
# bfw Beginning-of-frame line clock wait count
# vsp Vertical Sync Polarity (0 = active high, 1 = active low)
# hsp Horizontal Sync Polarity (0 = active high, 1 = active low)
# pcp Pixel Clock Polarity (0 = data sampled on rising edge of L_PCLK, 1
=data sampled on falling edge)
# oep Output enable polarity (0 - L_BIAS pin is active high in display mode
and parallel data input mode)
# acb AC bias pin frequency
# pcd Pixel Clock Divisor
# type 1 = Active Display 0 = Passive Display
# num 0 = Single Panel 1 = Dual Panel
# board 0 = Daytona 1 = Lubbock
# x width of panel

# The driver will use the first un-commented entry.
