# About
|
||
|
|
|
||
|
|
This is a manual test application for gesture recognition for touch devices
|
||
|
|
that are using the generic touch device API.
|
||
|
|
|
||
|
|
# Usage
|
||
|
|
|
||
|
|
This test application initializes the touch device and then waits for touch events using interrupts by default. Once touch events are received, it calls the gesture recognition. The application generates an output like the following:
|
||
|
|
```
|
||
|
|
Single Tap X: 276, Y:185
|
||
|
|
Single Tap X: 271, Y:178
|
||
|
|
Double Tap X: 271, Y:182
|
||
|
|
Pressed X: 235, Y:168
|
||
|
|
Moving X: 246, Y:170

To use the touch device in polling mode, the environment variable
|
||
|
|
`TOUCH_DEV_POLLING_MODE` must be set to 1. The polling period in milliseconds
|
||
|
|
is defined by the environment variable `TOUCH_DEV_POLLING_PERIOD`. It is
|
||
|
|
50 ms by default and can be changed by setting the environment variable
|
||
|
|
`TOUCH_DEV_POLLING_PERIOD` in the make command, for example:
|
||
|
|
```
|
||
|
|
TOUCH_DEV_POLLING_MODE=1 TOUCH_DEV_POLLING_PERIOD=100 \
|
||
|
|
BOARD=... make -C tests/drivers/touch_dev_gestures flash term
|
||
|
|
```
