G'day Peter,
Once again can I pass on my thanks for the time and effort yourself and everyone else involved in making the PicoMite what it has become. Like others have mentioned it is a great ride trying to keep up and try out all the new functions.
Can you please advise if the DS1822 (DS18B20) "Parasitic Power Mode" as shown on page 50 of the latest (06.00.01) manual is still supported, I decided to use it for the first time recently and found the following:
With MicroMite 5.05.05:
TEMPR() works in powered and parasitic modes
OneWire routine works in powered and parasitic modes
With PicoMite 5.08.00:
TEMPR() works in powered mode only
OneWire routine works in powered and parasitic modes
With PicoMite 6.00.01 / 6.00.02b8
TEMPR() works in powered mode only
OneWire routine works in powered mode only
This was on a PicoMite RP2040 blank chip with no options etc set
The scope shows the strong pull-up is not enabled when the sensor fails, this is also true on the OneWire routines in 6.00.01 / 6.00.02
I only have two sensors from the same batch but the fact they both work with the earlier versions indicates they should be ok.
Can anyone else confirm this?
Regards,
Lyle.
