DS18B20-Resolution change. How?

How can we change the resolution of the DS18B20?

I tried this in vein:

Code:

---

OWOut DQ, 0, [$CC,$4E, $00,$00,$3F]' set to 10bits
owout DQ,0,[$BE]
OWIN DQ, 0, [STR ID\9]

---

It returns only $FF, like there is no device connected.

The DS18B20 is confirmed to work OK.

The command to set the resolution is OK, as long as you're not using the alarms.

But you need to do a SkipROM before the Read_Scratchpad.
And the reset modes should be different.

Code:

---

OWOut DQ, 1, [$CC, $4E, $00,$00,$3F]' set to 10bits
; Convert and wait here
owout DQ, 1, [$CC, $BE]
OWIN  DQ, 2, [STR ID\9]

I mis-understood the reset pulse. Thought that if the device was set, say for 10 bits, and then a reset pulse was sent, it would set it again at the default 12 bit state.

Thanks Darrel, is OK now.
