yes hehe my is the second, i connect 5v, 0v and owbus does ds18b20 have a crc or another feature that shows the reset status or something else? i could check for example.... read 85 degree read the crc value (or another reset value) start of infinite loop: read 85 degree again read the crc value (or another reset value) if crc value = reset value, loop, else good read
i don't know if exists a reset counter or something like it in ds18b20, does anyone know?
