Hello Luc,
long time no hear, my old friend!
The API is a system only one called SysLCDBrightness. PLEASE in the name of
god try out the values for the UInt8 - 0 means off, 1 means full and then
its 2 to 255 for higher brightnesses!
I have tested this on all kinds of HPC ranging from the humble IIIc to the
cutting edge Centros. Here is some sample code:
//Brightness module
if(local.modifyscreen)
{
err = FtrGet(sysFtrCreator, sysFtrNumHwrMiscFlags, &flags);
if (!err)
{
if ((flags & hwrMiscFlagHasSWContrast))
{
if(local.wirelessscreen.snoopcontrast)
local.wirelessscreen.contrast=SysLCDContrast(true,1);
SysLCDContrast(true,local.dockedscreen.contrast);
}
}
err = FtrGet(sysFtrCreator, sysFtrNumHwrMiscFlagsExt,
&flags);
if (!err)
{
if ((flags & hwrMiscFlagExtHasSWBright))
{
int realbrightness;
if(local.wirelessscreen.snoopbrightness)
{
realbrightness=SysLCDBrightness(false,2);
switch(realbrightness)
{
case 0:
local.wirelessscreen.brightness=0;
break;
case 1:
local.wirelessscreen.brightness=254;
break;
default:
realbrightness--;
local.wirelessscreen.brightness=realbrightness;
break;
}
}
switch(local.dockedscreen.brightness)
{
case 0:
SysLCDBrightness(true,0);
break;
case 1:
SysLCDBrightness(true,2);
break;
default:
realbrightness=local.dockedscreen.brightness + 1;
SysLCDBrightness(true,realbrightness);
break;
}
}
}
}
All the best
Tam Hanna
