Hi I wanted to connect the LV-EZ1 ultrasonic range finder (sensor) to the de2 board. How do i connect this to the board this sensor gives a voltage depending on how far the object is located? ...

14 years agoWhen the *BW is open or held low, the TX output delivers
asynchronous serial with an RS232 format, except voltages are 0- Vcc. The output is an ASCII capital “R”, followed by three ASCII character digits representing the range in inches up to a maximum of 255, followed by a carriage return (ASCII 13). The baud rate is 9600, 8 bits, no parity, with one stop bit. Although the voltage of 0- Vcc is outside the RS232 standard, most RS232 devices have sufficient margin to read 0-Vcc serial data. If standard voltage level RS232 is desired, invert, and connect an RS232 converter such as a MAX232. Thats from the data sheet. I am not sure but i am thinking its the UART standard. How do i start with this implementation ?
