8-bit signed Touch Delta
|
|
|
|
Description
|
|
===========
|
|
|
|
This format represents delta data from a touch controller.
|
|
|
|
Delta values may range from -128 to 127. Typically the values will vary through
|
|
a small range depending on whether the sensor is touched or not. The full value
|
|
may be seen if one of the touchscreen nodes has a fault or the line is not
|
|
connected.
|
|
|
|
**Byte Order.**
|
|
Each cell is one byte.
