Function:
unsigned int ultrasound_read(long Address, unsigned char settings)
Description:
// This function receives one Byte via the corresponding UART from the Address
Precondition:
Call ultrasound_init(long Address) prior to use this function
Parameters:
long Address - Address of the UART (and therefore of the Ultrasound)
unsigned char settings - defines maximum distance to measure (1: 11m; 0: 5m)
Returns:
unsigned int - distance in mm
Remarks:
Distance in meter
