G'day Lizby,
Managed to find the RP2350-Zero purchased by mistake, GP29 does work with the DS18B20:

> option list
PicoMite MMBasic RP2350A V6.03.00RC4
OPTION FLASH SIZE 4194304
OPTION COLOURCODE ON
OPTION CPUSPEED (KHz) 200000
OPTION DISPLAY 40, 80

This is using the "Normal Power" option as shown in the manual, I had a heap of trouble with the "Parasitic Power" system as it seems to be quite dependent on device quality. Maybe this is causing what you are seeing.

Might also be worth trying TEMPR START with a long timeout, I think this helped with slow sensors. Strange it worked on the older version though  

Mick, the DS18B20 uses the one wire protocol so will work on any pin, the TMP37 etc is perhaps what you have in mind?

Regards, Lyle.
