Size of the ring buffer for the STM32 TSC touch library. The size of this
|
|
buffer together with the sampling-interval property in the tsc-keys
|
|
device tree node determines the time window of interest. A slope value is
|
|
calculated between the oldest and the newest value in the buffer to
|
|
generate a press or release input event.
