Add VM support for OneWire

[John Maloney]

The one-wire protocol is used by some peripherals such as the DS18B20 temperature sensor. It can also be used for communication between microcontrollers. It would be a useful addition to MicroBlocks.

OneWire support has been added to the databot VM to enable use of Dallas temperature probes. It is working well, so the next step will be to deploy for other boards.

That is a great feature, would you please add it to ESP32 too?

Thanks for the up-vote! Since it works well in the databot (an ESP32 board), it should be quick to add to other ESP32 boards.

[John Maloney]

One-Wire support (used by the Dallas DS18B20 temperature probe) is now built into all ESP32 VMs,

Thank you very much, it’s working fine
