===== Full Name =====

Control_Blinds

===== Library =====

LIB\Unipi

===== Version =====

V1.0

===== Description =====

!! Without time setting, the block is down!! 

The block is used to control the blinds either with the up/down command or with the percentage of position and rotation. For the proper functionality of the block, it is necessary to define times of the variables. 
  * The STOP button works by pressing both command buttons at the same time. 
  * **perc_rot** is inactive when leaving the top position for a period of **rotation_time**. 
  * **calib_time** it is the time that serves to calibrate the position. Calibration runs from the angle of the direction to the starting position at the top (0%). Ideally, set it up slightly longer than the full rollout time. 
  * **rotation_time** is the transition time between the minimum and the maximum of the blinds opening. For the proper functionality of the block, it is important to correctly set this value together with **rolling_time**. 
  * **time_delay** is the protection period that is triggered by the falling edge of the command up (down), During which the command down (up) is blocked. (Does not apply to the STOP button)
