Function description (Using Touch library) 

 

31 

4.1.1.21  

#define BASE_TRACE_SPEED_CHXX      [n] 

━

 

Sets the ratio between the existing data and the current data when updating the baseline. 

━

 

Previous value : Current value = N : 1 

━

 

If it is too high or too low, it may affect touch behavior. 

━
