Hi, 1 wire family is communication that sensitive with the timing. so you can't interrupt while execute the device. That's not entirely true: The timing within a timeslot is critical, but the timing between timeslots is entirely uncritical. In other words, you must not interrupt reading/writing a single bit, but you can do whatever you like between bits. I put some subroutine and example for DS1820, but I skip reading & check CRC. it is an extremely bad idea to omit checking the CRC! |
