Q: What changes do I need to make to the ADSLOAD.REG and ADSLOAD.HWT files to use a new display?
When you hook up a new display, we send you the cable drawing, jumper settings and display drivers needed to use that display. The REG and HWT files we send may not match the memory configuration you have on your system. But don't worry: It's easy to update your existing configuration files.
Simply paste the sections of the REG and HWT files from the files we send you as illustrated below, and you've updated your system for a new display:
ADSLOAD.HWT:
;XScale PXA255
;SHARP LQ64D343 VGA 640x480 TFT LCD
0x44000000 0x003018F8 ;LCCR0
0x44000004 0x0F0E0E7F ;LCCR1
0x44000008 0x192121DF ;LCCR2
0x4400000C 0x03300001 ;LCCR3, 8 BPP
;0x4400000C 0x04300001 ;LCCR3, 16BPP
;StrongARM SA-1110
;SHARP LQ64D343 VGA 640x480 TFT LCD
0xB0100000 0x00000080 ; LCCR0
0xB0100020 0x2A2A1270 ; LCCR1
0xB0100024 0x182021DF ; LCCR2
0xB0100028 0x00300003 ; LCCR3
0xC0000F04 0x00000008 ; Color depth: [08=8bpp] 10=16bpp 0=not enabled
; Important: Must match panel driver
ADSLOAD.REG:
;XScale PXA255
[HKEY_LOCAL_MACHINE\Drivers\Display\Intel]
;SHARP LQ64D343 VGA 640x480 TFT LCD
"CxScreen"=dword:280 ; 640
"CyScreen"=dword:1E0 ; 480
"Bpp"=dword:08 ; 8 bpp
;StrongARM SA-1110
[HKEY_LOCAL_MACHINE\Drivers\Display]
;Sharp LQ64D343 VGA LCD
"BitsPerPixel"=dword:08 ; [08=8BPP] 10=16bpp (must match .HWT)

"VertSizeMillimeters"=dword:59
"PixelsPerLine"=dword:280
"PixelsPerColumn"=dword:1E0
"HorizPixelsPerInch"=dword:8A
"VertPixelsPerInch"=dword:8A
"PaletteReverse"=dword:0 ;0 = Normal Mono, 1 = Reverse Mono(Inverted)
"Rotate"=dword:00 ; software rotation of panel--allows portrait mode
; [00=0 degrees] 5A=90 deg, B4=180, 10E=270

IMPORTANT! Make sure that all board jumpers are properly configured before connecting your display. Incorrect voltages can permanently damage your panel.

If you want to configure a particular display listed on our supported displays list, email us with details about the LCD you want to configure for your ADS product.

Using the original supplied set of ADSLOAD values for a QVGA 16-bit color display, I was able to connect a custom built display and everything worked fine (sending signal through some custom circuitry). I'm now trying to adjust the output of the display controller to generate a 290x218 pixel output instead of 320x240. To do so I used the values below, and I can't get it to work. Basically, the display values looked shifted horizontally, dramatically, so that what should have been the upper left pixel was actually towards the center of the screen! Any thoughts on what I might be doing wrong? Do these values look right? I've tried tweeking things, and can't make any progress. Thanks for any help...
ADSLOAD.HWT:
;proto display 290x218
LCD0xB0100000 0x00000080 ; LCCR0
0xB0100020 0x10102112 ; LCCR1
0xB0100024 0x000114D9 ; LCCR2
0xB0100028 0x00300F0D ; LCCR3
0xC0000F04 0x00000010 ; Color depth: [08=8bpp] 10=16bpp 0=not enabled
; Important: Must match panel driver
ADSLOAD.REG:
[HKEY_LOCAL_MACHINE\Drivers\Display]; proto display
"BitsPerPixel"=dword:10 ; [08=8BPP] 10=16bpp (must match .HWT)
"HorizSizeMillimeters"=dword:76
"VertSizeMillimeters"=dword:59
"PixelsPerLine"=dword:122
"PixelsPerColumn"=dword:DA
"HorizPixelsPerInch"=dword:3D
"VertPixelsPerInch"=dword:3D
"PaletteReverse"=dword:0 ;0 = Normal Mono, 1 = Reverse Mono(Inverted)
"Rotate"=dword:00 ; software rotation of panel--allows portrait mode ; [00=0 degrees] 5A=90 deg, B4=180, 10E=270

| Ed, since this is a custom panel, we'll work with you off-forum to get it configured. Cheers, Drew |
