==Touch==
 +
Used for mapping touch ADC values to display pixel co-ordinates.
 +
 +
<code>
 +
[4096, 4096] --> [320, 240]
 +
 +
[RawX, RawY] --> [PointX, PointY]
 +
</code>
 +
 +
Usually [PointX0, PointY0] is placed around 25% from the top-left corner, and the same for [PointX1, PointY1] except 25% from the bottom-right corner.
 +
This offsetting is needed because the touch film starts to distort outside of that rectangle, which would skew the touch results near the center of the screen.

==ULCD delay==
 
==ULCD delay==
 +
 +
There is a delay between switching the parallax barrier, and adjusting the backlight.
 +
These delay values determine how many VBlank events to wait on before switching the backlight curves to the appropriate mode.
 +
 +
This is needed only to prevent epillepsy from analog jitter causing unwanted mode switches, and both values are usually always set to 1 or 2.

Data block formats

Touch

Used for mapping touch ADC values to display pixel co-ordinates.

[4096, 4096] --> [320, 240]

[RawX, RawY] --> [PointX, PointY]

Usually [PointX0, PointY0] is placed around 25% from the top-left corner, and the same for [PointX1, PointY1] except 25% from the bottom-right corner. This offsetting is needed because the touch film starts to distort outside of that rectangle, which would skew the touch results near the center of the screen.

Somewhat misleading, these values are actually used for clamping the MCU's raw slider readings to comprehensible values.


Offset Declaration Description
0x00 s16 SVR2_Min Raw 3D volume slider values <= this map to 3D slider value 0.0
0x02 s16 SVR2_Max Raw 3D volume slider values >= this map to 3D slider value 1.0
0x04 s16 VolumeSliderMin Written to MCU reg 0x58. Volume slider values <= this map to volume value 0x00
0x06 s16 VolumeSliderMax Written to MCU reg 0x59. Volume slider values >= this map to volume value 0x3F

ULCD delay

There is a delay between switching the parallax barrier, and adjusting the backlight. These delay values determine how many VBlank events to wait on before switching the backlight curves to the appropriate mode.

This is needed only to prevent epillepsy from analog jitter causing unwanted mode switches, and both values are usually always set to 1 or 2.

Reading

If 0x1FF81006 is 3 or 4 or 7 or 8 or 9 then the callibration data is read from the EEPROM using the i2c:EEP service command 0x001000C0, using offset 0x000 for HWCAL0, and offset 0x800 for HWCAL1. Otherwise attempt is made to read CTRNAND:/ro/sys/HWCAL(0|1).dat instead.
