1.3. RP6V2– Setup
1.3.1. Signals to be connected to the mainboard
The following signals need to be wired from the main board if you want to use the signals.
a. ADC0 -> PIN_1 USRBUS1 (Sharp front)
b. ADC1 -> PIN_2 USRBUS1 (Gyro)
c. ADC4 -> PIN_5 USRBUS1 (Sharp rear)
d. PWRON -> PIN_3 USRBUS1
The following options are possible:
i. Connecting the Sharp Front & Rear sensor to ADC0 – in this case you have to switch the
Sharps sensors alternately on (time –multiplex) and read out ADC0. The Gyro sensors will be
read from ADC1.
ii. The RP6V2 provides two connectors to connect analog signals ADC0 and ADC1 to the main
board (see picture below).
Make the wire connection from the USRBUS1 PIN_1 (SHARP_Front) and USRBUS1
PIN_5 (SHARP_Rear) to ADC0 header and the USRBUS1 PIN_2 (Gyro) to ADC1 header.
HINT: To connect both ADC signals from the Sharp sensors will only work, if they
are not powered on at the same time! If you want to use the Sharp sensors in a
different application mode then they should be connected to ADC inputs of the
control board.
iii. Alternatively you can solder wires on the back of the mainboard PCB from USRBUS1 to the
signal of the header – which looks more professional.
Hint: The changes requiring average soldering skills!
Do some soldering test before, if you doesn’t feel well enough with such changes.
It is important to use a soldering iron with a slim tip.
