DS1820 and the microcontroller over RE6 or RB7 pins. The selecti on of either
of those two lines is done using J3 jumper. When placing the sensor in the socket
make sure that half-circle on the board’s silkscreen markings matches the rounded
part of the DS1820 sensor. If you accidently connect the sensor the other way, it
may be permanently damaged and you might need to replace it with another one.
During the readings of the sensor, make sure that no other device (except those in
1-wire network) uses the selected line, because it may interfere with the data.
