and the microcontroller via PB4 or PA7 microcontroller pins. The selection of either
of those two lines is done using J18 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 accidentally connect the sensor the other way, it
may be permanently damaged. Make sure to disconnect other peripherals (except
1-wire), LEDs and additional pull-up or pull-down resistors from the interface lines
in order not to interfere with signal/data integrity.

1-wire® serial communication enables
data to be transferred over a single
communication line, while the process
itself is under the control of the master
microcontroller. The advantage of
such communication is that only one
microcontroller pin is used. Multiple

a unique ID code, which enables the
master device to easily identify all
devices sharing the same interface.
