Hi,
DS18B20 works well in normal mode,
but I can't see anything to use parasited mode.

normal mode :
DS18B20
PIN 1 : VCC
PIN 2 : ONEWIRE DATA
PIN 3 : GND

parasited mode (see datasheet for differences in command sequences):
DS18B20
PIN 1 : GND
PIN 2 : ONEWIRE DATA
PIN 3 : GND

Parasite mode is not implement right now.

Do you have any example of parasite mode? I guest that there is an extra pulse to give power. I will check documentation on 1-wire.

[BUGFIX] - Broken Slave TWI Fixed (#1)
7e2f9f9 
* Add a testing program to test and burn slave and master.

Example command to upload slave using wio:
"wio run --target slave --upload --port /dev/ttyUSB0 --clean"

Example command to upload master using wio:
"wio run --target master --upload --port /dev/ttyUSB1 --clean"

* Add a README so anyone knows how to test using wio.

* Fix the commit where the twi broke at.

* Temporarily add the testing dummy program example to make it easier to
test.

* Fix the second bug, needed to power up the TWI::Slave::begin().

* Remove dummy testing "cosa-fix" stuff.

* Handle async case and sync case seperately.

* Fix spaces.
