Re: Range Finder Issue
After further investigation it would appear that if I connect or disconnect the HDMI cable to the Rpi with any power on the Rover mother board it locks up the Rangefinder. To avoid this I have to disconnect USB and unplug the battery before connecting/disconnecting the HDMI cable. My head hurts, goi...

Range Finder Issue

Re: volts.py output problem
Hi
I ran volts.py, lightsense_ambient, lightsense_surface and rangefinder, all returned values and I was able to see the value change when I manipulated the sensor/s, all except rangefinder this returned a steady value of 87. I put an obstacle at various distances but not change in the value.

If I edit the blacklist file and change the line to 'blacklist i2c_bcm2708, so i12c_bcm2835 is loaded, i2cdetect now works but the Volts.py modu...
