I'm using a 8 bit controller to make a scanning LIDAR. When connected to my Arduino Uno, it works fine but when I try to use an Intel Galileo, I get no response from the gimbal. The output from the Arduino Uno's serial during a send command is from 5vdc down to 0vdc. The same signal from a Galileo is from 4.5vdc down to 1vdc!!

Any suggestions?

Thanks
